re: Uniden and Milcom - Cresend 220 Mhz PA
There are at least two versions of the Milcom 220 Mhz PA. One is an almost plug and play onto the 224 Amateur Band. The Uniden ARX2125 pa is a same basic layout unit, but a bit of pain to convert up to 224Mhz. Some amateurs have been running them at reduced ratings. Here's a few pics of n2ckh's effort. http://www.n2ckh.com/125m_rptr.htm BK-Relm was selling NOS Uniden PA's for about $150 each, a real deal if you can convert it up to the amateur band. (or operate it at reduced ratings). Milcom - Cresend doesn't have a manual for the PA. I've been looking for one for some time. These units were used in the semi dead 220 ACSB trunking systems. A properly converted pa will do at least 150 plus watts. They are semi supply voltage dependent, power drops off fast below 26 volts. When they're done right, they are a quite nice power amplifier. cheers, skipp www.radiowrench.com/sonic skipp025 at yahoo.com > "John Everson" <[EMAIL PROTECTED]> wrote: > Hello to the group. > I have been cleaning out the garage.
