[Repeater-Builder] Re: On the topic of RCA radios
A number of years ago I picked up a TAC-310SX at a hamfest and spent literally days figuring out the programming scheme. I wrote a spreadsheet program that would calculate the eprom data for both VHF and UHF units and have since that time used it with half a dozen radios. If and when I escape the mid-Atlantic blizzard and get home, I can send you the spreadsheet or do the calculation for you. If you want me to burn the eproms, I can do that for you as well.

RE: [Repeater-Builder] Re: On the topic of RCA radios
I have a program I wrote for the UHF version that will generate the bin files for the tone eprom and the frequency eprom. I recently aquired a VHF model and am going to write the same for it. I have not spent the time to figure it out yet but the work I did on the UHF will make that pretty easy Tim, what band is yours? 73 K5ILS _ From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Kirk Sent: Sunday, February 07, 2010 11:40 AM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: On the topic of RCA radios A number of years ago I picked up a TAC-310SX at a hamfest and spent literally days figuring out the programming scheme.

[Repeater-Builder] Re: On the topic of RCA radios
The radio shown in the photo is called a RCA Tac 300, RCA's answer to a Maxar. On UHF Models it used crystals same as a Motorola Maxar, and if equipped with PL (separate board), the tone board used 2 precision resistors to select a tone frequency. In UHF 25 watts, VHF was 30 watts, think they were 10.7 IF, and I recall using Regency scanner xtals on the RX. Nothing fancy, plain jane mobile. Requires an amplified mic. A $50.00 Motorola Radius ebay mobile will be a much better choice, unless you have a strange urge to waste money on crystals. The RCA Tac 200 was a 2 piece unit similiar to a GE Mastr2 mobile.

[Repeater-Builder] Re: On the topic of RCA radios
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. Chris GMRS Inc. --- In Repeater-Builder@yahoogroups.com, w7...@... wrote: Hello, Are you familiar with the TAC-310SX?
