Can someone please double check me on this? I'm wiring up a Rascal interface so I can get my K2 on PSK. I'm pretty sure I'm right but would feel better if someone double checked me. I'm about to wire up the cable that will go to the mic connector. The pin out is: TxAudio - pin 1 PTT - pin 2 Radio Ground/Shield - pins 7 & 8 Thanks for checking me.
