All: I have a JRC automatic antenna tuner I'm trying to put into service. This is the companion tuner for the JRC JST-135 and JST-245 transceivers. The radios communicate with the tuner through a 1200 baud serial link. I'm very interested in learning the control language for the tuner. If anyone has any information on the protocol used between the tuner and the radio and can supply it, I'd be very grateful. Alternatively, if there's someone out there willing to work with me to discover the protocol with a serial analyzer, I'd be very grateful for that as well.
Thanks,
Dave WB4FUR
