Denton,
It's a long shot and most likely wrong, but you might try inserting an RF
Choke between the OM7 and the ALS 600. Over the years I have cured all
kinds of silly problems like this, and finally got to where I just always
place a choke between my transceiver and amp.

Ok an update.
Mic ptt has failed totally and on the air reports indicate rf is getting out
on my signal, using external ptt switch.
It does not matter which mic or which mic cable I use the results is the
same..rf imposed on my ssb signal, ppt not functional and the only way to go
to ptt is to use the external ptt switch hooked up to the aux port. It acts
like it has lost its ground in the mic jack.or other mechanical failure. I
won't know till I pull off the covers and dig out the magnifying glass to
take a close look.
wobbling the mic cord's connector on either end of the mic cord does
nothing.
I have done a master reset..
fun and games..
