Hi,
I used to buy GE Delta SX and RANGR radio decks along with S950 and S990 control heads. I had EEPROM code for those heads that allowed for using the key switches to program the channel data so one didn't need the suitcase programmer. Handy for the ham world for 6m, 2m and 440. Plus a Hi Band, Hi Split radio was fairly easily converted to 220 MHz.
Once I had Ham Flash code for the MPA, the old trunk mounted radios went onto the Shelves of Obsolete Electronics save for the Lo Band ones for 6m. And even those wound up on the SOE once Kenwood popped out the TS60. Those were a lot smaller, still 100w, and sported SSB as well as FM.
The MPA, mounted in the Vehicular Charger (what GE called their version of the Moto Converti-Com) with an external power amplifier was just a whole lot better setup. Especially for the much faster synthesizer locking which made for an awesome 3-level scanner.
And then NASA came along and wanted to buy some for the space shuttle amateur radio program, And then the NASA MPA moved to the ISS. That ham radio skunk works project sure did go a long way.
Anyway, when trying to sell the GE stuff at hamfests, no one wanted working radios, all they wanted was Adam-12 control heads. And the GE ones look nothing like those.
