I will post more about this soon....
Photos from the USB Sound card Mods
Adding of the transistor and wires to access PTT and COR
lots of soldering on smd
Small signal diodes to isolate COR input
the green wire is the COR input into the soundcard
A 5k resistor to ground on the COR input gets rid of the floating key issue.. (Radio turned off)
3 almost ready to go... adding the shielded audio cables
close it all up with heat shrink to keep the wires attached and not to short anything out while using
Modified radio for Allstar Link use for KC8AJH
A couple Raspberry Pi's all ready to go...
