This is another unique accessory that I developed to interface Icom equipment. Works with the AT-100, AT-500, IC-2KL and 7200/7000/703/706 transceiver using the DIN type accessory jack on the back of the radio.

Using your ACC jack, this interface passes all necessary 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 7000, 7200, 703 or 706 and AT-100, AT-500 or IC-2KL amplifier, this is what you need! 

 Thanks for looking!
