Greetings to all on the forum, I have a project that I need some help in getting pointed in the right direction. I am a Ham radio operator and have a remote tuner that is semi automatic.
It uses a binary input to pre tune the unit to settings manually entered into the unit during setup, then when given a "tune" command and a sample signal it fine tunes to the best SWRs.
It uses 5 binary inputs (as best as I can remember) and a tune command input, It is too far from my shack to run the binary signals out to the tuner so I would like to use some spread spectrum radios to carry the commands to the tuner, the radios have RS-232 ports for data.
I would like to control the unit with a rotary switch, I think 12 or so "rough" settings will give me the coverage I desire, I could use a diode matrix to give the rotary switch the binary word output needed to activate the tuner.
A serial signal should be initiated when the rotary switch is turned to a new selection or the tune command state is changed as the SS radios key on data and the outputs to the tuner should be latched until another change is initiated. It seems like it would be simple but
Thanks
