[Dx4win] Using PSK and ICOM IC756 Pro II

[Tony Lord]

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! G8DQZ

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
