Actually you have to double your power to gain 1/2 an S unit. Here is a cool chart. https://cbradiomagazine.com/power-in-perspective/

Yes that is a new version with HG finals. That is a very steep price. For that kind of money I would just have one built below. Just add the class B bias and SSB delay, still cost less and comes with a fan. https://carlbuilt.net/product/400hd/

The correct final is an RM3 but several threads here on the forum here show people using the 520 or 13n10. Not ideal but you can make it work. The kl40, 60, 200, and 203 used to be considered throw away amps. If you can fixit and make it work why not.

The used amplifier market has gotten ridiculous as far as prices. A good class AB or even B amplifier for SSB use is getting hard to find for a fair price. I would watch the for sale section of this forum. Facebook market place in your local area or a local ham fest are also options. You might...

What's the finals arrangement of the 10 pill? Is it a 2 driving 8?

If your recapping a radio get with https://klondikemikescapkits.com/ He is a forum member and sells quality parts/kits.

I know Baofeng's are kinda the Rodney Dangerfield of radio's but that's a good looking radio. For the money it seems like a good buy. I really love my Yaesu FT-70DR but I do have two older Baofeng radio's I use as well. The only two complaints I have heard is the UV32 has no belt clip and the...

Wow I sometimes laugh at my older posts. I could have toned it down a notch or two.

No reply's on this yet. I was messing around and did find this. Not sure how the HG finals behave when they get warm. Here is what happens in a class AB amplifier when it gets too hot: Thermal runaway: The core of the issue is that transistors become more conductive as they get hotter. In a...

I have two of these and they are great mics with an old school style.

I'm with you on most of that. I just can't associate the words quality and RCI together like that. Maybe some day they will get their $hit together and be great again.

Great find, glad it’s working for you. Now about that pic, I know you weren’t trying to talk skip on the bowl with a kl203. ✌️

That looks like a great little fan kit. The fact that you say the heat sink does get hot would be the exact reason why I would add a fan kit. I would rather be safe then sorry.

Take your pic, there are many options...

I have been a die hard Magnum Radio fan for just over 25 years now. Ran every radio they had and still own a Delta and two Omega Force radios. I have a Uniden Madison as well. My current mobile is a hard to find Magnum 1 radio. I messed with an Icom 718 off and on for several years but always...

A lot has happened. The quality of RCI products have tanked. Toshiba no longer makes their 2290 and 2879 finals. TexasStar went under and stopped making amps. Someone else is trying to bring them back but only the 350 and 500 remain. (All have HG finals) popular radios now are made by Anytone...

I think your first step will be to buy a better watt meter. To see the peak wattage (PEP or peak envelope power) you will need a peak reading watt meter. It appears you might have done the echo mod wrong it it did not work. Looks like that radio already has variable power so you should be...
