Record? Nowhere close. And a Henry 3K puts out nowhere close to 5,000 watts. The only Henry amp that ever put out 5,000 watts was the 8K Ultra. As far as pole fuse, a 3K draws less than 30 amps.

Cool story, but......
Well you can't read or comprehend what I posted. Yea, ring and squeeze, a Henry 3K does 2KW PEP, less than the driver drawer in my big Bertha. That takes 3 phase 220 at 20 amp per phase.( see first post)
Talking full carrier now, 5 KW at the antenna connections is normal. 7/8 heliax to a supermag ground plane, matching coil rewound with #4 solid copper. The mode, narrow shift AFSK (full duty) Up the little drive knob till the forward power pegs at 6 KW. "POP" and the industrial complex and transmitter go dead. and then deep doo doo.
Hey, you know when handles are on your final tube it means power. and the driver speaks for itself.

Can I ask a question? So you have a heavy duty transmitter. Does it get you to Mars? if the answer is no then why? I have been a ham since 2003, a lot less years than many here. YES an amp can do great things under really crappy conditions but only if there is someone to hear you. So...with a 11 meter foot warmer on a band that has been down in the dumps for a few years you and running RTTY which at best you can make contacts around the world at 30 watts , what is the point of all the power output?

Back to Mars or Venus for that matter, Lots of power needed to contact those folks (if they exist) on other planets. Not sure they are listening to 11 meters though...Actually why would they bother? Sorry if I sound prudish...its been a long day repairing scanners on the side with broken antenna connectors.
Well, this box is approved ON M.A.R.S. I never fired it up save for the one time. I did use the left rack like a QRP TX and did a great job at 2 watts. The driver drawer is equal to ETOs Alpha 77 amplifier. Some outfit in Denver made me a terrific offer just for the vacuum variables and roller inductors in the antenna tuning drawer, 5X what I paid for the 40 foot flatbed of this stuff. Sold the driver drawer to a ham buddy that badly wanted it for that much more. 700 pounds of copper in the transformer.
Still have the FRT24A, in storage till I get a place to accommodate it.

In the 70's when I was about 11 years of age, the FCC showed up and knocked on our door. They identified themselves and asked if they could come in and review my equipment (C.B. Radio). My parents said yes and they had a large green or gray colored box with a meter on it. My radio was sitting on a milk crate. They connected a patch cable from my radio to their meter and...nothing. They re-tightened the connectors again and it showed about 4 watts. I was miffed it wasn't putting out 5 watts (Hey, when you're 11...) They went on to explain what I had been doing wrong and then left in their unmarked van.

That Radio Shack RG58 and 1/4 wave antenna must've been pushing the ERP! ;)
Well you can have a dirty 4 watts that could bring this on, worse through an amp, worse yet, a class C amp.
Over driven or over modulated, bad audio filtering or none add to the junk.
I always made sure my emissions were clean as a pin at any power level

A little RM KL203P amplifier sometimes can make the difference between whether you are heard and can hear, or you're not and can't.

This can make a big difference to someone on the road looking for information.

At least, it has worked that way for me.

And for around 75 bucks.

Wow.

I always ran power when I was on 11m back in the 80s. It wasn't illegal power though. It's only illegal if you get caught.

mike
Funny part is with a license, the FCC can do more than just confiscate, that license says you know the rules and now subject to hefty fines.

Trust me, I can read and comprehend just fine, OM. This time, I will outright say it. Your story is fake.

A pole fuse is not a main or branch circuit fuse in a house
This is one of 3 fuses in the 7400 V primary to the transformers(3) The power company waived a hideous fine but that one fuse cost $220 plus the manhour labor. Not cheap by a long shot. The industrial complex over the wall never knew I was responsible or that could have let to litigation. I did get a cease and desist order from the Marshall.

I had an Interceptor 300 linear that I bought for one big reason, to work skip, and the lesser reason, to squash a nearby slightly younger kid's signal when he hassled me. It worked great for both, but I spent a lot of money on tubes for it.

I used to have about 35 90 minute cassettes of me talking all over the world from about the age of 13 until 19, when I sold my CB stuff just before I moved across the country. You can hear my voice changing on some of the early ones. I was sick a lot back then and on some of the recordings my voice sounded like an old lady, and others it was jut raspy, but on most of them, I was plugged up and sounded very nasally.

About the only place I never talked to was Japan. Made it to every other Asian country, such as S. Korea, Taiwan, Phillipines, etc but never Japan. I don't know what happened to those tapes, but when I moved back to NW Ohio, they didn't appear again. One is me talking to some woman in Barbados and I just can't understand her heavy accent, and it's hilarious as I'm at one point trying to end the whole thing and she won't let me go. I ended up giving her my PO box and she sent me a very explicit QSL card, which I still have someplace. I was like 14 and if she sent that to a 14 year old now it could be big trouble, but back then we laughed about it.

I agree with you on everything you said about mobile application and distance. Mobile is THE place to run power, in my opinion. You're already in a less than optimal scenario with your antenna and signal placement, and if you're on the go, you aren't pissing off your neighbors. I've known many guys who comfortably ran 200 to 300 watts mobile on AM that weren't a splatter nuisance.

I have the RM Italy 35-watt box (that actually swings close to 50w) and it's a perfect little mobile amp. Does quite well.


Your setup like this one?

Well, this is a CB radio forum board....

I don't believe in running lots of power at home with a good base antenna high in the air. But in the car, it sure makes a huge difference.

The picture is one of the really big mobile amplifier shoot out guys and if you lift his hood all you will see is alternators and belts everywhere. They are very clever to make sort of a Yagi to increase gain when doing the shootout, which probably gives them about 5dB gain over the single whip on the roof. If his amp put out say 5kW then 5dB of antenna gain would raise that to 15,811 watts.

The RM KL203P heater has a pre-amp feature as well, so it indeed can improve the reception in weak-signal cases and thus allow for the better receiving you speak of.

The little unit only takes about 10 amps to run. I power it via a cigarette lighter plug. In fact, it's only about the size of a couple packs of cigarettes, so it is easily accommodated in the cabin.

It sure has been worth the $75 I spent on it.

I have two of the KL35 boxes. They're just little guys, but mine swings over 50 watts if I drive it with very low output power. It was enough to take out two of my stepdad's home security cameras when I keyed the mic and sent a signal out over a home brew dipole I made for my kids there.

I have a KL203P on the way. I can't wait to try it out.

A KL203 and a West Mountain Radio CLEARSPEECH DSP Speaker are the combination which are the revolution in making an AM/SSB radio outperform all else than Amateur Gear used on 11-Meter.

Paired, it’s a $300 addition after tax/shipping.

Which maybe some might exhibit understanding know if they ran mobile and had to attach importance to timely information.

Hearing about some Interstate problems but three miles away is too little & too late in plenty of instances.

1). Where hearing 12-15/miles enables planning an alternate route.

2). And getting heard by locals a few miles off the Interstate confirms or changes that alternate route.

— One has his own vehicle deficiencies to overcome. And the deficiencies of the other guys radio rig.

I no longer find it surprising that other truck drivers who’ve made an investment of time (study) and effort (install & money) are equally good at map reading + understanding on-air directions while on the fly. Alternate routes aren’t automatically easy.

Relaying info back & forth plus monitoring what’s happening in that instant on the Big Road while also hustling a big truck down unfamiliar roads (suitable to vehicle type) is an all-hands-on-deck sustained effort.

Truly awful weather can ALSO telescope dead-serious highway problems into a few seconds of needing to make correct assessments just to avoid adding to an existing crash.

Hearing — and Getting Heard —have consequences past those who would kill the spirit of law in their childish insistence on the letter.

Had the tools but failed to use them effectively (or use them at all) is a typical ending to a report on pilot fatalities.

Not all problems can be avoided. Or should be. Judgment comes with experience and skill. Listening is a skill as what can matter is not always putative content.

Utilize the principle underlaying Radio:

Have the tools.

Use them to best effect.

As a matter of point, I’d seriously doubt more than 150W adds anything to a mobile rig (any vehicle) given mobile antenna deficiencies plus ordinary limits of CB Radio performance.

Ten to twenty miles sounds big. But it’s only a few minutes of driving and often not enough to correctly gauge first leaving then re-entering the Interstate without an even higher risk level incumbent.

120+ watts might get me heard by the guys discussing the wreck ten miles behind them. But twenty-five miles ahead of me. 75W sometimes doesn’t do the job.

Altetnately, good luck running thru Houston and thinking you can shut down AM-19 with 75-150W. Won’t happen, except for a few guys right next to you.

The guys on base stations (admirable ones, technically) are the trolls who with many hundreds of watts ruin the channel for everyone else. It’s the antenna system.

Want a mobile system worthy of the name? The above-mentioned pair plus the addition of MIX 31 & 61 ferrites plus other filter types will bring mobile performance to a level not understood by the next ten thousand users who believe they “know” what is CB Radio.

They don’t. Extra Class (all certs) notwithstanding. (Who may be the ones using Amateur gear on 19 from a fixed position; or have similar setups for mobile; “not legal use”).

Road conditions change constantly for radio use.

Have the tools. Learn to use them.
Apply as conditions warrant.

Truck drivers like you use the CB band for much more than just idle talk.

I'll bet the CB band was busy in Fort Worth this morning with that 100-vehicle pileup in the ice. Truckers with CBs were probably the first on the scene...indeed, IN the scene...giving localized warnings and other information to others who had CB radio equipment.

In such situations, there's nothing better or more prevalent than CB radios for up-close-and-personal local warnings even while the event is still unfolding. At times, that information can be lifesaving.
