SDR

Hardware

  • Flex-3000
  • PIC-IO prototype board for relay switching

In development:

  • Relay sequencer with indicator support
    • microcontroller-controlled, dual ptt support
    • NC to the antenna, NO to the preamp
    • Shut down voltage to preamp relays if fault is detected
    • wait for indicator to indicate relay is fully switched before allowing the radio and amp to ingage
      • in-line microphone support: 8 pin in and out connectors, ptt intercepted by mcu.
    • one relay for 24v to relays, everything else controlled directly by darlington driver ic
