80m Radio Orienteering Receiver
SignalSnagger is still in development. Product design and BOM contents are preliminary and incomplete.
SignalSnagger is an 80-meter band radio orienteering (ARDF) direction-finding receiver designed to operate in the Amateur Radio Service 3.5 MHz to 3.7 MHz frequency range. The receiver is designed to perform well in all common radio orienteering event formats: classic, sprint, and foxoring. SignalSnagger's frequency is stable and accurate using a precision temperature-compensated signal generator. A tuned loop with a "sense antenna," based on Dale Hunt's WB6BYU proven design, provides…
