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
- pin 2 = tx GND
- pin 3 = rh +12v
- pin 4 = rh GND
