I'm rehooking up St-809B DTMF Decoder board in my Kenwood TKR-720. I thought I took good notes but I guess not. ST-809B is still program for 123* Primary address and 789# Primary Reset, Programed as mode 2 (3 independent outputs).
I'm using + and - supply wires and Decode Latched output to relay to kill the transmitt ptt. also useRx Signal input form descriminator. It was all hooked up and working before I moved freq down in 2 meters and tried to clean up the cobbled up mess. I know I decoding DTMF because "STD" goes low on reciept of DTMF tone. I can EMail screen dumps of my software settings if needed. I have Parkinsons and I made something simple hard, but I hate to take the cover off something and see a cobbled up mess. Any help here in the group would be appreciate, if need be you can email me direct at "ka0jon at our-klan.com" I'm good on QRZ. then I can upload a file to the group case anyone else needs the info.
