Bought this a couple years ago to use on my ic-7300. It's good for hooking up 2-mics to one radio and switching on/off external speaker without having to plug/unplug your speaker or headset. I don't have room anymore for it. Asking $65.00 shipped. Cable is included which hooks up to Icom. Works as it should. Sold AS-IS. Thanks email is good on QRZ.
