interface for VX-6e and PC sound card
 

hi all, anyone has a schematics to connect an handheld (VX-6E)
to a PC for difgital transmisison, using the sound card?

The circuitry should have the PC sound output and the PTT
signal (from serial or parallel) connecting to the mic INPUT
of the radio (no separate PTT input in the radio)

thanks
