I kinda like this AI stuff. Yes, genuine United Chemi-Con capacitors are generally considered very good, high-quality components, especially top-tier series, ranking with brands like Rubycon and Nichicon; however, their reputation is mixed due to specific notorious series (like KZG) known to...

So just bringing up the Uniden 980 for a minute. You might test with a different watt meter. Those were low powered radios, maybe 10-14 watts peak and even less bone stock. When overturned they would fail.

First thought was the KL503 in either version is pretty much a low drive amp. That's a pretty hot radio for that amp. If the RF power on the radio can say dial SSB peak power down to 12-20 watts then it would be usable. On AM maybe 1.5 watts swinging 10-12. Many new radio's still swing pretty...

I can think of many other things radio I would spend 400 bucks on. I would say $225 would be a realistic price point if they actually wanted them to sell big.

9:50 mark shows 4 watt dead key. 1:44 mark shows 1 watt dead key.

They make two versions of the KL503, one with a driver stage and one with out. The RCI 69 base radio is advertised as a 100 watt radio. It will easily overdrive a Texas Star 350 or KL503HD. You need a bigger amp or smaller radio. Based on how your Texas Star amp is acting Vs your watt meter...

I really like those. For the money a nano vna is a heck of a deal also.

The splatter is onto other channels above and below the one your talking on. Then you have splatter to the second and third harmonic.

The only thing you could do is have a good tech actually do a receive alignment. Even then the famous RCI "white noise" will still be there. For the last 5-10 years RCI quality has been on a downward slide. I wouldn't waste hard to find Toshiba finals on that radio.

The majority of "cb" amplifiers are class C splatter boxes. There are a small number of nice AB amplifiers that were made. The Palomar tx amps from the 80's, The blue face Cobra xl and Magnum amps, a small number of blue face amps that say Palomar or Galaxy, The bulletproof line that are silver...

I want to say back in the 90's out of the box a Texas Star amplifier was sold as a CW keying unit (wink wink). Once you bought it they would do a conversion where a small cw board was removed that had been connected to the jack on the back of the amp. Most places would convert it for free as...

When the DX is rolling you can catch 909 Tony from Joe Gunn on channel 36 LSB. I think he runs the 8+8 cross. I have been looking at the Skipjack and 4V antennas. I wish the coax connection at the gamma was an SO-239.

Here is a nice read from an older thread. worldwidedx.com/threads/la-900-moble-amp.135044/

Yup MURS can be fun to talk local on.

Very nice amp.

Toshiba 2SC2879 is a high-frequency (HF) and very high-frequency (VHF) NPN bipolar junction power transistor. It was primarily designed for use in radio frequency (RF) linear power amplifier applications, especially in equipment such as amateur (ham) radio transceivers, commercial communication...

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.
