Thanks for the replies. Turns out I needed to invert the COS signal in the configuration and it started working.
I’m able to use most commands, but find *81 and *80 don’t seem to work. I get a tone after unkeying, but no information comes through. *70 works and *340894 works, so don’t understand why I can’t get ID and time to work - am I missing something? Thanks, Curt
