I have been a little delinquent in posting lately...    


With the Tour De Cure event coming up - it was suggested that I attempt to assmeble a digipeater to put up.  I had access to a tower location, so it was just a matter of assembling something to put up at the tower.


I used a Motorola SP50 radio, and a Raspberry Pi, running Raspbian, and Direwolf.  A usb audio device was used, providing both input and output.  The PTT for the radio was connected via the GPIO pins on the Pi.  The Pi is also powered directly from the accesory port on the back of the radio, via a 7805 voltage regulator chip.
