Jerry,

I don't know the answer but my AT-120 would not shut off with the 2nd 
press of the tune button with my 706MKII. I had to do a modification to 
the AT-120. It involved removing 2 caps and I think a daughter board, 
its been a long time since I did that modification. Icom had the 
modification at one time while I worked there. i would give it a try on 
the 7000, don't remember anything different in the tuner connections as 
the AH-4 works fine with it.
