ICOM IC-A5 power supply, audio and PTT

Power supply has not been described – therefore I created my own.

I used this cheap chinese LM5296, which was installed on the back of the plate. Cost about 2 USD/piece.
Adjusted it to 9.6 volts with 13 volts input (this is what battery output is).

Supply it is very stable and makes no noise. During transmision it consumes 0,7 AMPS @12 Volt (~8,4 watt)
