 Charlie: That happened with my ACK initially with certain frequencies.  I
 corrected it by moving the ACK antenna forward to separate it further from
 the com antenna in the tail.  Final position just in front of the tail
 access panel on the pilot's side.  No further problems.  Of note, prior to
 moving the antenna, I tried moving that phone cable all over the place, with
 no luck--the problem was apparently not in that cable, but rather induced RF
 in the ACK antenna itself...
