There is only one manual way to turn off the AGC and that is to do a "hold" on the AGC button. Youi can dismiss an intermittent connection in the 5 button, because that should randomly switch fast to slow and back, besides turning AGC off. One would also think that an intermittent 5 button would mess up other stuff as well.
You can test this yourself by setting AGC to S or F, then tapping XMIT, then doing a "hold" on AGC OFF. You will find that this will terminate the XMIT state during the hold and will NOT change the AGC to off state. IMHO, that makes the computer and/or programs, which can do it with a command, the prime suspect. ============== Universal suspect list for all K3 troubles -- trouble shoot in this order for quickest, cheapest path back to full operation and sanity, and public appearance of experthood: 1) RTFM (Adobe Reader search of PDF very useful) 2) Nothing in second place (maybe not in third place either) 3) Computer AND Operator (bad manual/program/OS AND confused operator) 4) Operator 5) Computer 6) RF in shack 7) K3 Regards and good luck... 73, Guy.
