Transmission Light

This is the thing that says whether you are transmitting, rehearsing, or both.

Design

It is currently controlled by Arduino (for serial control) triggered relays - hopefully having the Arduino and transistors on the same board soon

Relay control cable

Cat5 cable terminated with DB9.

  • pin 1 = tx +12v (Orange)
  • pin 2 = tx GND (Brown)
