Icom Amplifier/Tuner Interface
OPC-118a
by Bob W2ENY

The newer Icoms 725, 726, 728, 729, 735, 736, 737, 746, 746PRO, 756, 756 PRO I II III, 761, 765, 775, etc. refer to the OPC-118 adapter in their manual for interfacing to the AT-100, AT-500 tuner and IC-2KL amplifier... But this cable is no longer available new!!!!

This is another accessory that I developed to interface Icom equipment. Works with the AT-500, IC-2KL and transceivers using the DIN type accessory jack on the back of the radio. For those of you using the 8 pin DIN for other modes like RTTY, PSK31, sound in/out, no need to worry.

Using your ACC 2 jack, this interface passes all neccesary control voltages to the amp for ALC, T/R keying and auto-bandswitching. Just like Icom designed it. They just don't support it anymore...

The cable here is shielded and 4 feet long, so you can connect directly between the radio and amplifier or tuner. As I recall, Icom had you buying two cables to solve this solution.

If you have an ICOM radio and AT-100, AT-500 or IC-2KL amplifier, this is what you need!
