Transmission Light
From YSTV Documentation Wiki
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
