I HAVE ONE OF THESE I GOT MANY YEARS AGO IN AN ESTATE SALE ALONG WITH OTHER RADIOS . IT NEVER WORKED BUT I COULDN,T BRING MYSELF TO TRASH IT . I,M THINKING OF TAKING IT TO A TECH TO SEE IF IT CAN BE BROUGHT BACK TO LIFE . IT WOULD FIT PERFECT IN A SLOT IN MY MINI VAN . QUESTION , WERE THESE GOOD RADIOS ? don,t KNOW WHEN IT WAS MADE , BUT FIGURE IT WAS ONE OF THE EARLY 40 CHANNELS . |

I believe this is an SSB model, correct? It is highly modifiable and if you can get it going for a decent price it would make a good little radio for mobile/base use. |

YES , IT IS AM/SSB . IT IS THE ONLY ONE I HAVE FOUND THAT WILL FIT PERFECT WHERE I WANT TO INSTALL IT . I DON,T KNOW ANYTHING ABOUT THEM , BUT IF THEY WERE GOOD RADIOS , I WOULD BE HAPPY TO PAY TO HAVE IT FIXED |

I had a PC 122XL which I believe is the same as your radio except for the faceplate. It was a VERY good radio.
The noise blanker/anl would knock out most of the power line trash around here, and the SSB sounded very good.
They have the single-conversion Uniden µPD2824 SSB chassis.
Other radios that share your 122s chassis are:
Realistic TRC453, TRC465, TRC850, Uniden PC122XL, PRO-640e, and PRO-810e
I wouldn't hesitate to see about getting it fixed if it were mine.
Just out of curiousity, what is it doing (or not doing) wrong? |

I can tell you one thing about that radio from personal experience. Make sure that the SSB ALC (limiter) is in place and functioning before you use it on sidband.
The small size of the radio leaves enough effective "heat sink" area on the radio's chassis to run SSB with the limiter set correctly.
If you "clip" the limiter for AM (and AM ONLY) that alone won't hurt it.
If you clip the limiter so that the SSB ALC no longer works, the final will run WAY hot. Doing this raises the average SSB power without really improving the peak power all that much. Never mind how a SSB radio sounds with no limiter, but the average HEAT that the radio will produce is hard on it. Models with a larger chassis have more square inches of surface area, and the temperature won't rise so much. The PC-122 just doesn't have the surface area to dump that much heat.
Besides, they sound pretty good on SSB with the ALC set correctly.
