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
