Did some googling and looked at w2eny's page and have not found a definitive answer.  I'd like to wire up my 751 to a AT-150 so that the autobandswitching would work.  The I have the pinout for the plugs but no voltage levels so I'm not sure if they are compatible.  Anybody done this or know?

Thanks for any time Y'all can save me digging

Carl -

These 2 Icom products are of different design eras (Icom IC-751(A) is older).
I am not aware of ANY changes in voltage levels for signaling/control --
BUT be careful of direct CPU lines (no buffering) on early Icom radios that used the 24-pin Molex connectors!

The Icom IC-751(A) uses the 24-pin Molex connector and the Icom AT-150 uses
the 8-pin DIN (ACC) connector.  

W2ENY does build and sell the Icom cables (no longer available from Icom) between these 2 connectors.
 Bob use to sell a cable that took the IC-751(A) 24-pin Molex connector and breakout to the DIN 8-pin & 7-pin sockets found on later Icom transceivers.
Ask him to build one for you -- that would be ideal.

The specific pins used in the ACC 8-pin DIN are outlined in the AT-150 manual.

Greg,  Thanks!  I did reach out to Bob and he will make me one for less than the hassle of me gathering the connectors, pinout data and whatnot needed to put one together myself.  The autobandswitching voltage compatability was my main concern.
