Does anybody know where to pick-off the "squelched discriminator" audio, the line level audio input and the COS signals ???
The schematic shows J309 that appears to have some of this stuff, but the connector is "itty-bitty" - I can't find a mating connector anywhere !!! I opened the radio this morning and just went "sigh"... MilSpec, and I'm not very interested in completely tearing the radio apart to get to needed signals. I suspect that most (if not all) of them are on the PCB that you see when you pull the lid. I went in with a tiny multimeter probe and touched a pin going to the front panel (in search of the COS - AKA "Busy" line) and mnaged to touch two tiny pins at the sametime. POOF! No more radio. Thank God for warranties. My 60 year old 'fat fingers' are too 'fat' for this micro type work, and I'm a skinny guy! Hope somebody has already chased these signals and can post the info. !!! Thanks, Dave WB7CJQ
