> Hi All,
> 
> My 18 month old Omni VII has recently developed a 'funny' after performing flawlessly since purchased. 
> 
> This rig has the ATU which was installed at the factory.
> 
> When first starting the radio cold, whether connected to my usual antenna, other back-up antennas or a dummy load, upon activating the ATU, the rig will inject terrible feedback into the speakers and/or headphones that consists of a cross between a 60 cycle AC hum and RF feedback. It's really bad. 
> 
> The ATU hunts for a match but fails and the receiver seems somewhat de-sensed when it switches back to receive from the tune cycle.
> 
> then... 
> 
> After the radio has warmed up for 15-20 minutes it operates as normal with no sign of this condition throughout the remainder of its use during the current session. Once cold, it repeats again.
> 
> A conversation with Gary at TT Service suggested that I first do a master reset, which I have not done yet deciding instead to see if anyone else has had a similar experience or can offer any alternative suggestion.
> 
> My suspicion is an ATU component or SWR detecting circuit component that is nearing a failure??
> 
> I'm trying to first avoid clearing my settings via a reset or ultimately having to send it back to TT, which may have to be done in the end.
> 
> Open to any suggestions that can be offered.
> 
> Thanks in advance,
