[TenTec] Omni six-- heat related IF gain problem

[Chuck Guenther]

For several weeks now, I've noticed a pronounced reduction in gain of my Omni 6 after it has been on for a while.  When I first turn on the rig, I get an s meter reading of s-2 to s-3 on antenna noise, which degrades to s-0 after the rig has been on for a while.  The attenuation used to take a few hours to kick in, but this morning I noticed fading out in a matter of minutes.  Has anyone else experienced this?  I suspect a problem either on the 9MHz board or the PBT board.  Any hints would be appreciated.

Thanks & 73,
