IC-746Pro and phone patch.

Well so far I have learned that the 8 pin DIN plug is the correct plug for
hooking up a phone patch.

I have also learned that on that DIN plug, the pins needed are 2 - ground, 3
- PTT, 4 - Microphone in, 5 - Receive Audio, and if needed, 7 - 12 volts
(actually 13.8V).

I wired pin 2 and pin 4 on the DIN plug so I could cable up the SP-767P
external speaker and phone patch.

I have been looking for the manual for the SP-767P but have been unable to
find it. I am also looking for the plug that couples the phone line to the
SP-767P but will probably simply rig one of my own tomorrow if it doesn't
turn up.

I have a Yaesu SP-767P and would like to use it with the Icom. I am
beginning to think it takes going through the microphone jack in the front.
I hope not.

If you can point me to a set of instructions or website that describes the
best approach I would appreciate hearing from you.
