Raspberry Pi Fox Hunt Controller
Objective:
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.
Items Used
- Raspberry PI 2
- GPIO Board and Bread Board
- Additional Bread Board
- Baofeng UV5R
- Mike and speaker cable for the UV5R
- Headphone plug for the PI
- 2 – 4N37 Opto couplers
- 3 – 1000 ohm resistors
- 1 – 1000uF capacitor
- Jumpers

I like your little Crossbend project . I also would like to say that you live in a beautiful part of the country . When I was out there working on a radio system that covers part of Virginia for a Virginia power co-op I got to visit several mountain tops and I got to drive through your part of town .and wish that I lived out there to on unfortunately I live in the west coast Los Angeles area.
