John Thanks for your comments, Pin 4 of ACC1 is called MOD on page 13 of the Pro II manual which describes each pin of this socket. My software (MULTIPSK) uses audio in and out to control all functions. Consequently your advice confirms my thoughts, Pin 4 AF input and Pin 5 AF output, ground of course being Pin 2!
Many thanks 73's Tony!

Can any one comment, > please! Thanks............. Hi Tony - I have the PROII. On page 20 of the manual is a diagram for connecting AFSK - can be used for RTTY and PSK. It shows pin 1 being used for -FSK- RTTY keying. It's -NOT- for audio input! AF input (AFSK RTTY or PSK, or HELL, MFSK16 etc) is pin 4. Ground is pin 2. AF out is pin 5. I don't see anything about "mod". Hope this helps! 73 - John, WA9ALS
