Build a foxhunt controller that interfaces to a Baofeng UV5R to monitor reception and send out messages at programmed intervals after receiving a signal.
This is a simple project for the PI. It uses one output and one input. The input monitors the speaker output of the Baofeng UV5R. This radio has a 3.6V offset voltage when the squelch opens. This is sufficient to activate a opto-isolator to trigger the receive input on the PI. An output from the PI triggers the radio transmit through another opto-isolator. Audio from the PI is passed to the UV5R on the mic plug.
