 Hello..I am using an IC-275A on 9600 baud...mods I used were essentialy by
W0SL, Roy. I only have a hard copy...its here some where!!. I also added a
bit about access to the rear of those 2 sockets.
 However, the nitty gritty is that the TX audio can be fed to pin #2 of the
AQS socket with no mods to the radio. There is a pre-set gain control in the
circuit (R 152). I did not touch this, but adjusted the deviation via the AF
output level from the modem.
 The mods that Roy described were on the receive side and to do with wiring
the mic up/down to one of those rear sockets...used for AFC.
 Good luck..can guarantee it does work..hi.
