[ICOM] 756 Pro II Problem

[Larry Young]

Remove the computer and CI-V connections to the radio. Test the Radio into a 50 Ohm load. If it works correctly, then  retest, and add one cable at a time until it begins to act up again. Leave  the amp off during these tests. You should also verify the power cord for good connection to the radio and the inline fuses.

It doesn't happen when I press the Transmit button.  It occurs only when I key the radio with the computer.  If I press a RTTY, or CW macro, the radio goes off.  This will happen on any band.  I first thought that RF was causing the problem, when I operated with the amp. Now, only 25 watts will cause the problem.  This also happens with any of 4 antennas connected.
