Late to the subject. I don't know if you found a way to get that mic to allow scanning. I bought a tk880 off ebay. when I first programmed it It would not let me scan after I changed from programming cable to mic. So a couple of attempts later to program it. I found in the kpg49d software if you go to Edit>scan Information there is a check box to Off Hook Scan. This fixed me up
Hey Ya'll, I'm new to it all. Right or wrong I have a couple of radios off ebay coming. I have read alot of information here. Thanks for that. I am interested in gmrs for several reasons including travel back up communications, family communications and possibly data if that becomes a thing. WRDE414
