[MRCG] WTB Collins 714E-3 Control Box for 618T-2

[Mark J. Blair]

My 618T-2 that I bought at the 2019 MRCG came with a 714E-2 control box (without the CW and Data positions on the function knob). I think that a 714E-3 (with the CW and Data positions) would be a better fit for the way I'd like to use my radio, because I'm thinking of using my Dovetron MPC-1000T AFSK modem with it. If I understand the wiring diagrams correctly, the Data position just sets the radio to USB and grounds an additional line (not used by the radio) to indicate that data mode is selected. I figure that I could use that line to patch the Dovetron in or out of the system. Luckily I haven't bought the expensive mating connector for my 714E-2 yet, because the 714E-3 uses a different expensive connector.

If anybody has a 714E-3 in good condition available for sale or trade, please contact me.
