[arm-allstar] Interfacing with Icom UR8050

[Matt]

Thanks Steve.

I've managed to get it working by adjusting the logic and now it's all 
good. Just need to find some local users to test it now then it will be 
put back into service on Wednesday.

> Fob TX Audio - Repeater LI (Modulation signal input with 300-3000Hz 
> 6dB/oct emphasis)
> Fob Ground - Repeater GND
> Fob RX Audio - Repeater LO (Detected signal output with 300-3000Hz 
> 6dB/oct de-emphasis)
> Fob PTT - Repeater EXT PTT (External PPT input. Connect to ground to TX)
> Fob COS - Repeater BUSY (Becomes high impedance while receiving)
