The Tac 310Sx was a short run radio, mfg in Japan, final assembly in PA. When you got a good one they worked great, weak PA's were a problem. Much smaller than the Tac 300 and programmable with scan. As I recall we used a plain old 2716 prom reader/burner when our RCA factory programmer bit the dust. Probably dirt cheap on ebay. If you find a burner, read the existing chip, COPY it to a new chip, would not take a chance on changing the existing one as they must be UV erased before rewriting.Chips are available everywhere cheap. Good luck finding anyone who still programs the units.

TacTel Systems, some RCA LMR people, acquired the RCA Land Mobile radio Div. including the RCA Service Co.'s mobile radio field service. TacTel went belly up a few years later. Fidelco continued for a few years after that with the service part and went out of business. IIRC 1992. "Eric Lemmon" <wb6fly@> wrote: That makes good sense. According to a news release, the RCA Land Mobile Radio division was acquired by TACTEL Systems, Inc., of Pittsburgh many years ago. 73, Eric Lemmon WB6FLY
