[TenTec] Omni VI TX power low on one band

[Speer, Doug]

I posted a similar question a couple of weeks ago.  My Omni VI Plus which I bought from a SK estate had been in storage for many years.  When I bought the rig it seemed to work fine on 40-10m but I was getting low output ~20 watts on 160m and 80m.  I sent it to Ten-Tec and they replaced the finals and drivers at a rather healthy cost.  I got the rig back just this past Monday and now all bands seem to be working per spec.  I asked Ten-Tec for a technical explanation of how final output transistors could work fine on the upper frequency bands but not on the lower frequency bands but never got an explanation other than "the finals were bad".

Your problem may be similar however I would certainly run to ground your LP filter theory before looking at final output transistors.
