Oh my... you mean someone is still trying to use one of the early solid state GE Radios..?
Circa 1985 I received a number of the mentioned GE Radios as part of a trade in toward a new radio fleet purchase. Out of the 6 radios I received, 5 had problematic pa sections that required critical adjustment... else they were horrible spur generators and even oscillators of their own original design. >From more than one source I heard the PA Sections of the early GE Radios were "prone to sing" so the radios went away in favor of the trusty Master Pro models (worked like a charm every time). Motorola has the similar nightmare pa issues with some of their early varactor tripler designs... if they were out of alignment it was a very careful road (steps) to return them to proper operation. Yep, we should note the differences between the TPL (affectionately known as the "Toilet Paper Line") Amplifiers and the GE TPL Radios. cheers, skipp > "Eric Lemmon" <[EMAIL PROTECTED]> wrote: > Skipp, > Perhaps we should differentiate between the General Electric > Transistorized Progress Line (TPL) mobile radios of the late > 60's and the "TPL" rackmount power amplifiers of the recent > decade.
