Motorboating; what is it, 'why?', and how to fix it?

Jack of all trades, master of none!!

Mar 25, 2018

I just completed a build of a little Single Ended EL84 guitar amp. I tried to follow a schematic from a Fender Tweed Princeton amp as best I could, but this was a 'left-over' parts project and I really had to rather 'make due' in some cases. The Princeton schematic uses a 6V6 and is at a much higher voltage than my PT could produce. I have a schematic for a similar amp that Antique Electronic Supply sells as a 'kit'...there MOD102 kit. I also incorporated parts of it into this build as well; particularly the output section and PS supply. I did use a choke......a Hammond unit, a 156 I believe......1.5H, 200ma, 50 ohms. Anyway....... the amp is about 98% there! It's up and working, has 'acceptable' numbers in most places. I've got about 230V on my EL84 plate, about 190V on the screen, and about 125V on the two 12AX7 plates. I'm running a 150 ohm cathode resistor, bypassed with a 100uf/100V cap, and showing about 5V across that resistor which I believe calculates to about a 32ma current draw on the tube...which is a 'new' JJ 6BQ5. I say I'm at about 98% because I have one remaining issue, which is that the amp will 'motorboat' from about 3/4 volume level on up. If kept below this level, it sounds and plays fine. But, hit about 2/3 to 3/4 on the VC and it breaks into this oscillation........audible even with the guitar vc turned all the way down. So, just looking for some suggestions as to what to do about this? Any help would be appreciated. Many thanks!! Tom D.

Motorboating is a low frequency oscillation, often due to feedback though the power supply. Coupling caps shouldn't be too big, power supply filters may have to be larger if your supply has more droop than Fender's original. The original 5E2 circuit used 22K and 8 uF for the filter to the two 12AX7 stages - you may have reduced that resistor - if so (or even if not!), increase that filter cap and see if it helps. Also try a bigger filter cap after the choke.

Ultrasonic oscillation due to poor circuit layout can sometimes present as motorboating, if it pulses because of grid blocking. It's especially important to keep output stage anode wiring well away from the signal path in low-level stages. A scope would tell the story.

My PS filters are: 1 & 2, 47uf @ 350V, 3, 22uf @ 350. That should be more than ample to support the 'upgrades' from Fender's 8uf. Coupling caps: Actually this amp was built using the tone circuit from a 5E2 Princeton. That amp uses a 250K pot for it's tone control, with a .0005 on one side of it.....going to the plate of the 12AX7, and the other end to the input side of the tone pot. The other side of the tone pot goes to a .005 which goes to ground. There's still a .02 from the first plate connected 100K ohm resistor...then to the input side of a 1 meg VC pot, where the other side of the VC pot simply goes to ground. I should mention that the wiper of the tone control goes to the junction of the 100K resistor at the input side of the VC pot. MIke, I'm going to go back and look at layout issues...... but I'm thinking I should be OK. Hard to tell.......and I wish I had the 'scope' skills to figure it out that way. I'm wondering if the fact that this problem doesn't resent itself unit you get to 2/3 to 3/4 of the drive level on the VC doesn't mean something? If I were to cut the voltage by increasing the resistor......do you think that might change anything? TSD

Fish fingers and custard!

Does it motorboat with no input connected if you turn up the volume? If so check all ground connections and look for ground loops caused by multiple connections

Dr. a, yea, it does do it with nothing plugged in. I also have a 'grounding' input jack......so, the input grid on the first section of the 12AX7 is 'grounded' . I guess that means that the problem lies somewhere within the tone control part of the circuit, the Volume control, and the second stage 12AX7, yes? I didn't see any obvious 'grounding' issues, but I don't have any kind of 'star' ground with this......it's more of a 'chassis' ground much like the way the AES kit is designed and built.

The 6BQ5 screen shouldn't be connected to the same power supply node as the 12AX7s - it draws more current than they do, so variation in screen current makes the supply voltage change, which makes the plate voltage on the first stage change, which gets amplified by the following two stages.. and the screen current changes some more. So, move the 6BQ5 screen to the FIRST B+ point like Fender did, and increase your cathode resistor to get back to the previous bias point.

If you can post a high resolution schematic, such that we can zoom in on it and it doesn't look too small to read, that would be helpful.

Doc, posting a picture of the AES MOD schematic. That was what I used as the basis for both the power supply and output section. The tone section came from the 5f2 Princeton schematic. I used a 10K on the input (along with the 1 meg), and the both 1.5K 12AX cathodes are bypassed with 25uf/25v caps. Tom, my PS is a CT type PT with the CT to a chassis ground, and both HV outputs to a 1N4007 diode. The output of the diodes goes to a 47uf cap and the Hammond choke. The output of the choke is the B+.....along with another 47uf cap. The OT is connected here as well. From there I go to a 18K / 1W resistor, which feeds the screen, a 22uf cap, and a 1K resistor. This 1K feeds the 12AX7. What I'm now thinking is that I should have yet another filter cap in this section.......as at this point, I don't. I'll try putting something there and see what happens. Would be great if that's all it took!!

Are you saying you did not have a power supply cap for the 12ax7 preamp section? And do you have that 100k resistor there as well on the 5f2 schematic?

Yes, I came off the 22uf to the screen......and also a 1K that fed the two 100Ks that went to each 12AX plate. Tomorrow I'm going to see if I've got another 22 or a 20uf @ 350 or 300V and put that at the 1K and see what happens! Hopefully that'll fix it!! If not....back to the drawing board.....and the forum!! TSD Larry.... you know I've got one of each around here, plus a little Yamaha on the little John boat! TSD

junk junkie

Inclined to agree about splitting the screen and the driver stage power supply up. Honestly I'd run the output transformer from HV, the screens from B1 and the driver from B2 but thats me. Adjust the 200 ohm cathode resistor if needed to get the bias right, and/or increase the size of the 100 ohm resistor if you really need less screen voltage. As it is, the screen supply will sag horribly through a 22K resistor. I guess that might be on purpose, I can't get my head around guitar amps though. Stuff that is sometimes done on purpose there would be something you'd just cringe at in a hifi amp.

Thain, that's rather the idea behind me doing this. In having built about 20 of Mr. Gillespie's Magnavox 8600 amp, I think I understand that unit fairly well now. Not completely, but I think I've got the basic idea. I also built that MOD102+ kit from AES. Pretty simple, and it worked perfectly well. I ended up finding 3 power transformers, 2 of which were the 269EX and one that was about as close to the 269EX as I think you could get. I also had some SE 5K output transformers, so I decided to attempt to build another of the amps similar to the 102+ kit. If I haven't mentioned it already, the '+' version of the 102 Kit is rated at a slightly higher output wattage (8 vs 5), and comes with a few extra bells and whistles like having a 'pull' switch on each of the 3 controls; 1 for 'bright' on the treble control, pull for 'mid boost' on the bass control, and the VC pull switch adds some further gain to the amp.....or so it's supposed to do. The '+' also comes with a 3-way off/standby-on/run power switch vs just off/on. Anyway, I wanted to build just a simple SE EL84 version of something like the tween Princeton of Champ.......so using those diagrams as well as both the MOD102 and the '+' diagram, I set out to build the thing based on using the 3rd of my PTs as well as one of my existing OTs. The idea was to keep it as simple as possible, but have a 'tone' control vs no tone or Bass/Treble. So, I had to figure out how to run all these different aspects together into one amp....using my parts, and actually making it work. And, aside from the motor-boating problem, I'm 'almost' there! So, to address this motor-boating, the suggestion is to move my screen supply to the same place as the B+. Just another question before I do this, and I think Tom Bavis addressed it with his post above. But, in doing as suggested, the Plate and the Screen on the OT are going to be at 'about' the same voltage.....and in so doing, I'm going to experience a pretty significant increase in current draw from the tube. In looking at that MOD schematic (in my post #9), they're running both the 6BQ5 screen AND the 12AX7 from the same B+2 position and that amp doesn't have that problem. I also wonder if the difference in voltage between 6BQ5 Plate and Screen....if that's not part of what is producing some of the characteristic sound of the amp? I know that in many Hi-Fi amps the screen and plate are at about the same voltage level. I've seen some schematics where the plate is actually running at a lower voltage.....but I believe most of these diagrams are where a UL OT is used. But, in this MOD design, the difference is pretty great.....like 75+volts! In moving the plate and screen voltages to being nearly equal, will I loose some of the performance aspects of the amp that are actually rather appealing as a guitarist? Also, I think this is going to play hell with the Bias......and I'll be looking at using something like that 470 ohm resistor that Fender used on that Princeton as pictured above in post 9???

OK, after reading Tom Bavis's post above, I got to thinking about how I'd addressed my builds on Dave Gillespie's Maggie revisions.......and in that build, like the MOD102, both have only 3 stages to the PS. However, when I construct Dave's amp, I add a 4th stage because I add a dropping resistor after my 5AR4 rectifier. In this revised MOD build, I added a choke. So..... in effect I also had 4 stages, but had only put a PS cap in 3 of them. My 1 - 3 stages had 'capacity', but my 4th stage, after my 1K resistor and in feeding the plates on the 12AX...I had no cap. So.....I added one! I dug through my supply of filter caps, found a 20uf @ 350, and installed it at that 1K resistor. Problem fixed!!! Motor-boating is gone, and the amp plays great from just barely opening the VC all the way to full throttle! The ONLY symptom that it exhibits that I find a bit odd is that at about 3/4 volume there is a dip in the noise level. As you go from all the way 'down' to gradually turning 'up' the VC, you begin to hear some amplification coming from the speaker. Even with nothing plugged into the amp...which 'grounds' the input jack...there is still some audible noise as you turn it up. But, at about 3/4 to 7/8 of the way up...there's like a 'spot' where the noise level drops off. Yet, when I 'play' the amp......the sound increases throughout the sweep of the VC. So, no 'dead spot' in amplification......just in that background noise. I'm going to live with it for now! The amp sounds great and performs well, and should be easy to 'repeat'. My next step will be to attempt to draw up a diagram of the final product, post it, as well as do a little photo shoot of the thing and post that as well. To all above, MANY THANKS for the guidance and suggestions. I'm sure the other changes suggested might have worked equally well......but this 'final fix' seemed easiest to try, and having it solve the problem, I'm just glad I don't have to go through and mess around with trying to get the bias right again. Happy Soldering!! Tom D.

I don't know that I'd move the screens to the same place as the B+, I'd move both the screen and the plate "over one". Output transformer straight off the rectifier, screens after the 100 ohm, driver after the 22K. If the screen sag is integral to the sound of the amp, leave the screens where they are and add another branch off the supply with a 22K resistor to a cap. Feed the driver off that. I wouldn't tie the driver downstream of the screen just because they will still have some level of interaction that might cause you trouble. basically the idea is to not have the screens and the driver connected together so they can't interact with each other.

Thain, I get what you're saying, and I understand the idea. I may give a shot at trying your suggestion....just to see if it makes the amp sound any different/better. BUT...that said.....as it's working now, it's really pretty impressive for a little 'flea' guitar amp. I've heard a lot of these over the years, including OE Fender units......and a good number of them didn't sound nearly as good. This one is still a bit 'gainy'......in that it's into 'break-up' after about 1/4 to 1/3 on the VC. But......from a 'player' perspective, that's not necessary a bad thing. It becomes a matter of 'how' it breaks up.....if it's 'controllable'.....and not so compressed or 'faltering' that it just sounds bad. So, I'm really not all that disappointed with that aspect of it. The little 'noise' glitch rather confounds me.....but not to any level that I believe it's in need of further attention. Rather, I'm just going to consider it as a personality trait. But, if changing the PS leads around as you suggest can correct that....then perhaps it's worth a try. I just know that this change will 'initially' play hell with the bias......and that's another balancing act that takes time too. Anyway.......all good comments and thoughts......so, many thanks! Tom

Tom Click to expand...

I'd say the noise is VERY 'typical' of guitar amps! As my amp is built, I have a 10K resistor off the input jack and going directly to the input grid on the first stage of the 12AX7. The MOD amp uses just a straight wire, and the original Fender uses a 68K. I chose the 10K only to temper the input just a bit, without really bedding it down. I tried to build it such that all the passive parts made connections without needing any further leads or wires. But, where the VC connects to the input grid of the second stage of the 12AX, I DO have a shielded wire there! With the exception of the plate lead to the second stage, I don't think I have any 'wires' cut to make any connections. Even my input grid connection to the 6BQ5 is made directly with the resistor vs any leads. I just built one of the MojoTone Tweed 'Deluxe' kits......and this amp that I just build is, I believe, much quieter. 'Noise' isn't really a problem. You mention taking a class.......is this one of Gerry Weber's 'Amp Camp' deals? I know he does those pretty regularly! I have had many good conversations with him over the years. About 20 years ago (or so) I was DEEP into guitar amps! I not only owned a good number of them, but I had people in the area bringing them to me for 'repair'. I think over the course of about 6 to 8 years or so, I must have gone through well over 200 guitars amps for one reason or another. In 'collecting' them myself, I couldn't afford to have them professionally 'tuned up'.....or have hums fixed, or anything else for that matter! I was buying these things at junk stores, pawn shops, music stores, etc, all over the east coast as I traveled from town to town, state to state. Any 'deal' I could find on a guitar or amp.....I bought it! Single life and 'divorce recovery' will do that to you. I also got myself into a band......so I justified all this by 'playing' as well. Of course, I'm absolutely NO GOOD!!......lol. But....I had fun. Anyway, the need to fix all these things necessitated me learning how to do that myself....as I couldn't afford the professional costs of service. Luckily for me, I had a good Mentor in the form of Jeff Bober, formerly of Budda Amplification and now of 'East' amplifiers! Budda got sold to Hartley Peavey....but it was quite successful for a good long run. I think Hartley killed it! Anyway, to finish the story...... the band broke up....and I wanted to move......so I sold about 90% of all that I had, closed up the basement shop, and move from Annapolis to Baltimore. Along the way I discovered an old Dynaco ST-70. That was 20 years ago now.....and it's been 'home audio' ever since. But, this sticking my toe back into Guitar amps is kind of fun. I believe I was still very much in the early learning stages back then. While I could 'set a bias' or change coupling caps, or even make a broken amp work again.....I had no real understanding of what I was doing. That has come to some level over the past 20 years with the home audio stuff. But, even now, I struggle, as indicated here in this thread. Not putting a 4th cap into the PS filter section is rather a 'rookie' mistake IMHO! I hope you have fun with building the amp you're going to build. I think the Princeton schematic above is a pretty good choice if you want at least one tone control. I think some of the Champ amps had just a VC....which in retrospect is perhaps how I'd do it next time! The guitar already has a tone control....so why add one to the amp? (rhetorical question....not a conversation starter!!....lol) OK.....gotta run! TSD

Very cool! I would enjoy one of webers classes, I will be using one of his alnico speakers in my amp but no to it being his class. My circuit analysis teacher is really into building guitars so he has a guitar building class at the college that I don't need but just want to take for fun. I'm always showing him the stereos I'm working on and he is always working on his guitars, really cool electronics teacher. Thanks to getting into audio circuits about 5 years ago and audiokarma and youtube the electronic courses are a breeze.

Motorboating (electronics)

Motorboating (electronics) explained

In electronics , motorboating is a type of low frequency parasitic oscillation (unwanted cyclic variation of the output voltage) that sometimes occurs in audio and radio equipment and often manifests itself as a sound similar to an idling motorboat engine, a "put-put-put", in audio output from speakers or earphones. [1] [2] [3] [4] It is a problem encountered particularly in radio transceivers and older vacuum tube audio system s, guitar amplifier s, PA systems and is caused by some type of unwanted feedback in the circuit. The amplifying devices in audio and radio equipment are vulnerable to a variety of feedback problems, which can cause distinctive noise in the output. The term motorboating is applied to oscillations whose frequency is below the range of hearing, from 1 to 10 hertz , so the individual oscillations are heard as pulses. Sometimes the oscillations can even be seen visually as the woofer cones in speakers slowly moving in and out.

Besides sounding annoying, motorboating can cause clipping of the audio output waveform, and thus distortion in the output.

Although low frequency parasitic oscillations in audio equipment may be due to a range of causes, there are a few types of equipment in which it is frequently seen:

Older audio amplifiers with capacitive (RC) or inductive (transformer) coupling between stages. [5] [6] [7] [8] This design is mostly used in vacuum tube (valve) equipment. Motorboating was a problem throughout the era of vacuum tube electronics but became rare as vacuum tube gear was replaced in the 1970s with modern solid state designs, which are direct-coupled . The recent resurgence in popularity of traditional tube-type audio equipment in guitar amplifier s and home audio systems has led to a reappearance of motorboating problems. The problem is sometimes caused in older equipment by the evaporation of the electrolyte from old-style "wet" electrolytic capacitor s used in the power circuits of legacy equipment, or in equipment of any age where an amplifier stage is sensitive to feedback via power supply rails , and can be remedied by replacing/upgrading the capacitors.
In both old and new designs, even mostly directly-coupled operational amplifier circuits, feedback through the power supply rails can generate ultrasonic oscillations that vary in amplitude at a low frequency ( squegging ) due to the power supply voltage sagging as oscillations build up (the long time constant coming from the power supply reservoir capacitor) in such a way that the low frequency is audible even though the high frequency fundamental is not. Such problems can be difficult to diagnose. [9] [10]
Audio equipment associated with radio transmitters , particularly transceiver s in two way radio s, such as Citizens band , FRS , which have automatic gain control (AGC) or squelch noise control. Malfunctions in the AGC or squelch circuits, which have long time constant s, can cause low frequency oscillation. Another possible cause, sometimes in combination with the first, is leakage of the strong radio frequency (RF) signal from the transmitter into the receiver audio sections, which can cause quenching oscillations. This is a RFI problem, caused by inadequate shielding or filtering to keep the RF out.

As with all electronic oscillation , motorboating occurs when some of the output energy from an amplifying device like a transistor or vacuum tube gets coupled back into the input circuit of the device (or possibly into an earlier stage of the amplifier circuit) with the proper phase for positive feedback . This indicates there is an unwanted feedback path through the circuit from output to input of an amplifying stage. The technical conditions for oscillation, given by the Barkhausen stability criterion , are that the total gain around the feedback loop (comprising the amplifying device and the feedback path) at the oscillation frequency must be one (0 dB), and that the phase shift must be a multiple of 360° (2π radian s). Since most amplifying devices, transistors and tubes, are inverting, with the output signal 180° opposite in phase from the input, the feedback path must contribute the other 180° of shift.

Many types of parasitic oscillation are caused by small interelectrode capacitance s ( parasitic capacitance ) or mutual inductance between adjacent wires or electronic components on the circuit board, which create an inadvertent feedback path. However these usually cause oscillations of high frequency , at the upper end of or above the passband of the equipment. This is because the phase shift of the small reactances in the feedback path, which increases with frequency, only become significant at high frequencies. Low frequency oscillations like motorboating indicate that some device or circuit with a large time constant is involved, such as the interstage coupling capacitors or transformers, or the filter capacitors and supply transformer winding.

In vacuum tube circuits, a common cause is feedback through the plate power supply circuit. The power supply provides DC current to each tube's plate circuit, so the power supply wiring (power busses) can be an inadvertent feedback path between stages. The increasing impedance of the filter capacitors at low frequencies can mean that low frequency swings in the current drawn by output stages can cause voltage swings in the power supply voltage which feed back to earlier stages, making the system a subaudio oscillator. This is caused by inadequate power supply filtering or decoupling. The electrolytic capacitors used in equipment of 1960s vintage contained liquid electrolyte, which dried out over decades, decreasing the capacitance and increasing the leakage current, and these are often the cause.

One solution suggested is a "capacitor job", replacing all the old electrolytic capacitors. [11] A more radical but comprehensive solution is to add modern IC voltage regulator s, or replace the entire power supply with a modern regulated one.

In radio equipment

In equipment that includes radio transmitter s, motorboating can be caused by radio frequency interference (RFI), the strong radio signal from the transmitter getting into audio or receiver circuits. Receiver audio circuits with automatic gain control (AGC) have a long time constant feedback loop which adjusts the gain of the audio stage to compensate for differences in audio level from causes like different speaking voices. Squelch circuits used in two-way radio s to cut out noise similarly have a feedback loop which turns off the audio when high frequency noise is detected.

If the inaudible radio frequency (RF) transmitter signal is inadvertently coupled into the receiver's audio signal path, it can trigger the AGC or squelch circuit to reduce the gain. Then, after a delay time set by the circuit's time constant, the circuit increases the gain again until the amplitude of the radio signal triggers another gain reduction. This repetitive cycle is heard as motorboating.

An example might be a 27 MHz Citizen's band radio in a car, connected to the car's 12 volt DC supply. If the decoupling capacitor s which bypass radio noise from the power supply wires are missing or inadequate, or the long power leads pick up excessive RF from the antenna then it is possible for the RF transmitter signal to enter the radio's receiving circuits through the supply wires. This then causes the motorboating to occur.

From the Q&A

With TJ Byers

Motorboating Radio

I have an old Minerva radio — at least that's what it says on the little plate just below what used to be a glass dial that runs across the top of the radio.

I would like to get this up and running, but have no schematic or even a model number to give you. It is a tube-type radio with six tubes and two rectangular cans mounted on the chassis. The front of the radio has three knobs: it appears that one is for on/off/volume and one is for tuning. The third, I don't know what it does. I'm able to get the filaments to light, but instead of music, I get a loud hum. I am sure that the capacitors are dried out and need to be replaced. Any help you can provide about this relic would be appreciated.

It sounds like your antique is a typical AC/DC, superhet radio from the post WWII era. You can identify this breed by looking at the tube numbers, which should include a 35W4 and a 50C5. And you are quite right about the hum: the electrolytics are bad. However, the rectangular cans you see on top of the chassis are not electrolytics, but instead IF transformers. If you turn the chassis over, you'll probably find a paper electrolytic riveted to the chassis via a metal band. It may be a two- or three-section device (it contains more than one capacitor), which can be replaced with single electrolytics. However, you need to replace all the sections, even if only one is bad, because they share some parts in common and there is a good likelihood that the other sections will fail soon. The values typically range from 30uF to 80uF at 150 volts. However, finding an exact replacement isn't necessary. Any capacitance of equal or slightly larger value will work. Same for the voltage — equal or higher. Be sure to observe polarity and dress the leads with shrink tubing. A good source of tube-type replacement capacitors is Just Radios at www.justradios.com/capkits.html . By the way, your mystery knob is a tone control.

Rural municipality launches motorboat service

Post Report

Aanbookhaireni Rural Municipality in Tanahun district has launched a motorboat service in the reservoir of Marsyangdi Hydropower in a bid to promote tourism.

The service provider, Botebora, entered into an agreement with the rural municipality and commenced commercial operations on Sunday, according to Botebora Chairman Bishnu Dhakal.

Dhakal said the motorboat operation began immediately with an investment of Rs10 million. The company plans to expand its investment to construct facilities including a beach restaurant, floating deck, river viewpoint, restroom, and a motorboat service centre along the reservoir’s shore.

Different fees have been set according to the duration of the ride. According to the company, a motorboat ride costs Rs250 per person for 6 to 8 minutes, Rs500 for 10 to 12 minutes and Rs 1,000 for a 15 to 20-minute ride.

The motorboat station can be reached by travelling 14 km from Mugling towards Pokhara and 10 km from Dumre Bazar towards Kathmandu.

What Does Motorboating Sound Like?

What does it sound like? Anyone have a audio clip?

Sounds just like a short burst of digital audio being heard through an analog only radio.

Ryfly said: What does it sound like? Anyone have a audio clip? Click to expand...

2 cycle or 4 cycle?? :roll: :lol:

It's a low frequency oscillation that can sound like someone blowing rasperries, ir can even sound like a very low note played on a tuba. If the frequency is really low, it an sound like a small engine putting.

Silent Key (April 15th, 2023)

In reference to scanners and digital audio, it refers to hearing the digital noise that is a voice transmission, before it's been decoded back into voice. I never considered it to be a motorboat type sound until people on RR started calling it that - it was most often referred to as a diesel engine before the motorboating comment came around. There's a sample of digital Motorola IMBE audio (sometimes called P16) here .

US military rescued mariners stranded in the Pacific after they used palm leaves to spell 'HELP' on the beach

The US military this week rescued three men who had been stranded on a Pacific island for days.
The men were spotted by a Navy aircraft after they used leaves to write "HELP" in the sand.
An American officer hailed it as a crucial "act of ingenuity."

In an unusual scene seemingly out of a movie, the US military this week rescued three individuals who were stranded on an island in the middle of the Pacific Ocean after they used palm leaves to write "HELP" in big letters on the beach.

The lost mariners spent more than a week stuck alongside their damaged boat at Pikelot Atoll, a tiny island that's part of the Federated States of Micronesia, before an American military vessel recovered them on Tuesday, US Coast Guard Forces Micronesia, Sector Guam said in a Wednesday statement .

A US Navy reconnaissance aircraft spotted the men from above on Sunday, leading to a breakthrough moment in the rescue operation.

"In a remarkable testament to their will to be found, the mariners spelled out 'HELP' on the beach using palm leaves, a crucial factor in their discovery," Lt. Chelsea Garcia, the search and rescue mission coordinator, said in Tuesday's Coast Guard's statement.

"This act of ingenuity was pivotal in guiding rescue efforts directly to their location," Garcia added.

The three mariners initially set off on a March 31 voyage from Polowat Atoll, which is around 100 nautical miles southeast of Pikelot. Nearly a week later, on Saturday, a relative of the men reported them missing to the US military, which quickly mobilized the search and rescue operation, according to the Coast Guard.

cloudflare business plan support

What does Cloudflare do | How does it work | Business Model

Today, the Internet is the lifeblood of business and the primary vehicle of commerce and communication for people around the world. While it was brilliantly architected to deliver fault tolerance and robust connectivity, it was not designed to deliver the security, millisecond performance, and reliability required for businesses today.

For decades, several vendors have looked to address the core limitations and vulnerabilities of the Internet for businesses that operate online. These vendors built a range of standalone hardware boxes to address the emerging security, performance, and reliability requirements.

And then the cloud happened. In recent years, the technology industry has transitioned from on-premise hardware and software that customers buy to services in the cloud that they rent. Organizations find themselves at different points in this transition to the cloud.

But regardless of where a company falls on this spectrum, they all face a common set of challenges: they exist in a complex, heterogeneous infrastructure environment which exacerbates the fundamental problems of the Internet more than ever, and the on-premise band-aid boxes that they once relied upon to solve these problems were never designed to work in such an environment.

Cloudflare’s mission is to help build a better Internet. To understand how we analyzed the business model of Cloudflare. We understood what does Cloudflare do and how does it work.

What does Cloudflare do? How does Cloudflare work?

Cloudflare, founded in 2009, is a global cloud services provider that delivers a broad range of services to businesses of all sizes and in all geographies—making them more secure, enhancing the performance of their business-critical applications, and eliminating the cost and complexity of managing individual network hardware.

Cloudflare has built a global cloud platform that delivers a broad range of network services to businesses of all sizes around the world—making them more secure, enhancing the performance of their business-critical applications, and eliminating the cost and complexity of managing and integrating individual network hardware.

Cloudflare delivers a suite of deeply integrated products that serve as a unified control plane for Cloudflare’s customers. Customers can quickly and easily join Cloudflare by using just one of Cloudflare’s products and expand over time by adding most products with a single click. Cloudflare’s integrated suite of products consists of

solutions for an organization’s external-facing infrastructure (such as websites, apps, and APIs) to deliver security, performance, and reliability,
solutions to serve an organization’s internal resources (such as internal networks and devices),
developer-based solutions: By leveraging Cloudflare’s serverless platform, developers can build serverless applications that scale without needing to spend time and effort on infrastructure or operations.
Consumer offerings for individuals to have a performant and secure Internet experience

Cloudflare provides businesses with a scalable, easy-to-use, unified control plane to deliver security, performance, and reliability across their on-premise, hybrid, cloud, and SaaS applications. Cloudflare started building an efficient, scalable network. It forms the basis of Cloudflare’s platform for deploying products. Together, the development of Cloudflare’s network and products create the interconnected flywheels that drive Cloudflare.

Network Flywheel:

Cloudflare has created a network architecture that is flexible and scalable and gets more and more efficient as it expands. Cloudflare designed and built its network to grow capacity quickly and inexpensively; to allow every server in every city, to run every Cloudflare service; and to shift customers and traffic across Cloudflare’s network efficiently.

Cloudflare refers to this architecture as “serverless” because it means it can deploy standard, commodity hardware, and Cloudflare’s product developers and customers do not need to worry about the underlying servers.

As Cloudflare manages the execution and prioritization of code running across its network, it can optimize the highest-paying customers’ performance and effectively leverage idle capacity across Cloudflare’s network. Cloudflare has chosen to utilize this idle capacity to create a free tier of service—which has generated a substantial global scale for Cloudflare.

This scale makes Cloudflare an attractive partner for Internet Service Providers (ISPs) globally, reducing Cloudflare’s co-location and bandwidth costs. As Cloudflare’s network grows, these dynamics become even more powerful.

What does Samsara do | How does Samsara work | Business Model

Product Flywheel :

Cloudflare began with the idea of serving the broadest possible market. Cloudflare made its products affordable with its entry-level plan for free, in part because of the cost advantage of Cloudflare’s network.

Cloudflare’s machine learning systems improve Cloudflare’s products with every customer’s request, optimizing Cloudflare’s security, performance, and reliability globally. Cloudflare’s distributed and proprietary network is the core of Cloudflare’s technology and enables it to move data seamlessly from nearly any point on earth in a fast, efficient, and reliable manner.

What is the business model of Cloudflare?

Cloudflare’s business model benefits from Cloudflare’s ability to serve the needs of all customers ranging from individual developers to the largest enterprises, cost-effectively. Cloudflare focuses on the efficient onboarding of new customers and the expansion of its relationships with Cloudflare’s existing customers over time.

Cloudflare’s symbiotic relationship with ISPs and the efficiency of Cloudflare’s serverless network architecture allows it to introduce new products on Cloudflare’s network at low marginal cost.

The business model of Cloudflare generates revenue primarily from sales to Cloudflare’s customers of subscriptions to access Cloudflare’s network and products. Cloudflare made $656 Million in 2021 , a 52% increase from 2020. As of 2021, Cloudflare had over 140,000 paying customers across more than 170 countries.

Pay-as-you-go customers : Cloudflare’s pay-as-you-go product solutions are available in several configurations. Cloudflare offers Pro and Business subscription plans through Cloudflare’s website per registered domain, and it is common for customers to purchase subscriptions to cover multiple Internet properties (e.g., domains, websites, application programming interfaces (APIs), and mobile applications).

Cloudflare’s Pro plan provides basic functionality to improve applications’ security, performance, and reliability, such as enhanced web application firewalls and image and mobile optimization.
Cloudflare’s Business plan includes additional functionality often required by larger organizations, including service level agreements of up to 100% uptime, dynamic content acceleration, and enhanced customer support.

Contracted customers : Cloudflare’s contracted customers consist of customers that enter into contracts for Cloudflare’s Enterprise subscription plan. Cloudflare’s agreements with contracted customers are tailored and priced to meet their varying needs and requirements.

Key elements of Cloudflare’s business model include:

Free customer base : Free customers are an important part of Cloudflare’s business. These customers are typically individual developers, early-stage startups, hobbyists, and other users and, like Cloudflare’s pay-as-you-go customers, sign up for Cloudflare’s service through Cloudflare’s website.

Cloudflare’s free customers create scale, serve as efficient brand marketing, and help attract developers, customers, and potential employees. These free customers expose Cloudflare to diverse traffic, threats, and problems, often allowing Cloudflare to see potential security, performance, and reliability issues at the earliest stage.

Significant investment in ongoing product development : Cloudflare enhances the capabilities and functionality of Cloudflare’s global network with new products that are innovative and powerful and can be quickly adopted by Cloudflare’s customers and helps Cloudflare grow a free and paying customer base. That, in turn, provides Cloudflare with greater knowledge and insight into the daily challenges that Internet users face.

Efficient go-to-market model : Cloudflare has built an efficient go-to-market model that enables its business to acquire new customers and expand within the existing customer base rapidly and cost-effectively.

New customer acquisition : Cloudflare focuses on driving an increased number of customers on Cloudflare’s infrastructure platform. Through Cloudflare’s pay-as-you-go offering, a customer can subscribe to one of Cloudflare’s many plans and begin using Cloudflare’s network within minutes, with minimal technical skill and no professional services, allowing Cloudflare to rapidly acquire a large portion of paying customers and at significantly lower customer acquisition costs.
Expansion of Cloudflare’s existing customers : Cloudflare’s relationships with customers often start with servicing a portion of their overall network needs and expand over time as they realize the significant value of Cloudflare. Customers can then add additional products as they seek to consolidate onto one infrastructure platform to meet all their security, performance, and reliability network requirements.

Cloudflare Powers One-Click-Simple Global Deployment for AI Applications with Hugging Face

Makes Workers AI and Hugging Face integration generally available; deploying serverless AI is now easier and more affordable than ever

Cloudflare, Inc. (NYSE: NET), the leading connectivity cloud company, today announced that developers can now deploy AI applications on Cloudflare’s global network in one simple click directly from Hugging Face, the leading open and collaborative platform for AI builders. With Workers AI now generally available, Cloudflare is the first serverless inference partner integrated on the Hugging Face Hub for deploying models, enabling developers to quickly, easily, and affordably deploy AI globally, without managing infrastructure or paying for unused compute capacity.

Despite significant strides in AI innovation, there is still a disconnect between its potential and the value it brings businesses. Organizations and their developers need to be able to experiment and iterate quickly and affordably, without having to set up, manage, or maintain GPUs or infrastructure. Businesses are in need of a straightforward platform that unlocks speed, security, performance, observability, and compliance to bring innovative, production-ready applications to their customers faster.

“The recent generative AI boom has companies across industries investing massive amounts of time and money into AI. Some of it will work, but the real challenge of AI is that the demo is easy, but putting it into production is incredibly hard,” said Matthew Prince, CEO and co-founder, Cloudflare. “We can solve this by abstracting away the cost and complexity of building AI-powered apps. Workers AI is one of the most affordable and accessible solutions to run inference. And with Hugging Face and Cloudflare both deeply aligned in our efforts to democratize AI in a simple, affordable way, we’re giving developers the freedom and agility to choose a model and scale their AI apps from zero to global in an instant.”

Workers AI is generally available with GPUs now deployed in more than 150 cities globally

Today, Workers AI is generally available, providing the end-to-end infrastructure needed to scale and deploy AI models efficiently and affordably for the next era of AI applications. Cloudflare now has GPUs deployed across more than 150 cities globally, most recently launching in Cape Town, Durban, Johannesburg, and Lagos for the first locations in Africa, as well as Amman, Buenos Aires, Mexico City, Mumbai, New Delhi, and Seoul, to provide low-latency inference around the world. Workers AI is also expanding to support fine-tuned model weights, enabling organizations to build and deploy more specialized, domain-specific applications.

In addition to Workers AI, Cloudflare’s AI Gateway offers a control plane for your AI applications, allowing developers to dynamically evaluate and route requests to different models and providers, eventually enabling developers to use data to create fine tunes and run the fine-tuned jobs directly on the Workers AI platform.

Cloudflare powers one-click deployment with Hugging Face

With Workers AI generally available, developers can now deploy AI models in one click directly from Hugging Face , for the fastest way to access a variety of models and run inference requests on Cloudflare’s global network of GPUs. Developers can choose one of the popular open source models and then simply click “Deploy to Cloudflare Workers AI” to deploy a model instantly. There are 14 curated Hugging Face models now optimized for Cloudflare’s global serverless inference platform, supporting three different task categories including text generation, embeddings, and sentence similarity.

“We are excited to work with Cloudflare to make AI more accessible to developers,” said Julien Chaumond, co-founder and chief technology officer, Hugging Face. “Offering the most popular open models with a serverless API, powered by a global fleet of GPUs, is an amazing proposition for the Hugging Face community, and I can’t wait to see what they build with it.”

AI-first companies are building with Workers AI

Companies around the world trust Workers AI and Cloudflare’s global network to power their AI applications, including:

“ Talkmap helps customers uncover and surface real-time conversational intelligence and insights. With millions of customer conversations daily and the need for a fast turnaround for CX & EX outcomes, Cloudflare’s developer platform has helped us keep storage costs and latency low. We’ve selected Cloudflare to help us scale our generative AI service and simplify our runtime architecture so that we can stay focused on adding customer value for conversation insights in the contact center.” -- Jonathan Eisenzopf, Founder and Chief Strategy & Research Officer, Talkmap
“ ChainFuse transforms unstructured data chaos into actionable insights, ensuring every piece of customer feedback, issue, and opportunity is heard and valued. Using products such as Workers AI, AI Gateway, and Vectorize, we have successfully analyzed and categorized over 50,000 unique conversations from places like Discord, Discourse, Twitter, G2, and more. Having access to 28 AI models for any task—and swapping them on the fly—allows us to be accurate and efficient at scale.” – George Portillo, co-founder, ChainFuse.com.
“ Discourse.org is a modern, open-source discussion platform powering over 20,000 online communities from small hobby groups to forums for some of the largest companies worldwide. Discourse leverages Cloudflare’s Workers AI to run embedding models to power our popular ‘Related Topics’ feature. This produces relevant results within communities, giving community members new opportunities to find and engage with topics they are interested in. Workers AI is currently one of the affordable, open-source ways we can provide Related Topics using a high-performing embeddings model to give our customers an avenue to provide their community members with a new way to discover more relevant content and improve engagement.” – Saif Murtaza, AI Product Manager, Discourse.org
“ Simmer brings the swiping of dating apps to the recipe and cooking world, to bring couples together over a meal they both enjoy. Simmer has continually adopted Cloudflare products as the platform expands, and Workers AI was no exception; we use Workers AI embeddings and large language models, such as Mistral 7B, to help us create a personalized experience for users on the app, including curated recipes based on preferences. We go to Cloudflare first to explore if their products fit our use case since they’re so easy to work with. Using Cloudflare products also helps us save a lot on costs as we grow our startup.” – Ben Ankiel, CTO, Simmer
“ Audioflare uses AI to convert, examine, condense, and translate brief audio files into various languages. We heavily count on Workers AI for streamlining AI-related tasks including audio file processing, sentiment evaluation, language translation, and maintaining AI’s overall efficiency and dependability. We’re impressed with Cloudflare’s ability to simplify the backend operations of our app. We believe in Cloudflare’s consistent improvements and dedication, and feel confident about growing with their platform.” – Sean Oliver, creator of the open-source LLM repository, Audioflare

Motorboating (electronics)
Motorboating (electronics) In electronics, motorboating is a type of low frequency parasitic oscillation (unwanted cyclic variation of the output voltage) that sometimes occurs in audio and radio equipment and often manifests itself as a sound similar to an idling motorboat engine, a "put-put-put", in audio output from speakers or earphones.
Motorboating; what is it, 'why?', and how to fix it?
Motorboating is a low frequency oscillation, often due to feedback though the power supply. Coupling caps shouldn't be too big, power supply filters may have to be larger if your supply has more droop than Fender's original.
Gow to resolve a "motorboating" problem
The radio is now working and receives very well AM stations. No hum but there is "motorboating" that disappears when the volume knob is turned close to maximum. When the volume is lowered "motorboating" appears again. I checked the volume control variable resistor with the ohmeter and seems to be ok. Three of the tubes (77, 78 and 6A7) have ...
What causes "motorboating"?
Location. Tucson, AZ. Dec 27, 2008. #11. Skypilot007 said: ...If you're getting the motorboating sound for an entire transmission then its probably a weak signal on that particular voice channel that your scanner is not decoding. This sounds like what is most likely happening.

What is mean by "motorboating"?

The term predates anything digital by about 6 decades or so. Did motorboating have the same meaning BEFORE digital, but not caused by digital apparatus?

DMR RF (motorboating) on TNC circuit : r/amateurradio
DMR RF (motorboating) on TNC circuit. I have a USB sound card that feeds audio into two el-14 1:1 600ohm audio isolation transformers. The PTT circuit is shown here. I'm getting a strong motorboating effect on DMR. Putting a choke on the kenwood to dual 3.5mm audio cord near the radio did not remove the issue.
general-el: motorboating noise |Radiomuseum.org
general-el: motorboating noise. 08.Apr.20 10:42. In most cases, motorboading occurs, if the electrolyt capacitors of the B+ voltage have lost their capacity. In this model this is a dual elyt C23A & C23B, both should have 50μF. Try to solder an elyt of 47μF in parallel to C23A, and probably another in parallel to C23B.

SDS200:
If it is indeed motorboating, that is normally caused by the scanner breaking into oscillation due to poor power supply voltage regulation. It should become worse as you turn up the volume. That is common with battery powered scanners. If the SDS200 problem increases with volume, I would substitute a different AC adapter.
