Hello Everyone: Has anyone used the QYT KT8900D transceiver for Allstar? I can't find any information on how to get the COR out of this radio. It's not on the mic jack pin out list and I can't find a schematic. Any help will be appreciated. Thank you. -- 73 from the land of the Pakipika ... Aloha, Pat KH6KL 444.925+ 41592
