[TenTec] Omni VI Problems, conclusion

[Ken Brown]

Hi all,

I got the 30 meter XTAL OSC. coil removed, slug unscrewed, coil 
reinstalled and slug put back in with dental floss to make the fit tight 
enough to work. I have adjusted all of the XTAL OSCs, according to the 
procedure Ten-Tec told me, and now the rig puts out reasonable power on 
all bands. It is putting out 100 watts on all bands except 15, 12 and 
10, where it is 80 to 90 watts. There is no more "drift and relock" 
sound on any band.

The mixer balance control also had an affect on the power output 
especially on 80 and 160. I adjusted it to get full 100 watts on 160 and 
80 meters. Hopefully the power I measured is not including any 
significant 5-5.5 MHz VFO component. I suppose the right way to adjust 
that pot would be to monitor the output of the mixer with a spectrum 
analyzer, and adjust for minimum VFO and XTAL OSC levels and maximum LO 
level. I have not looked at it with a spectrum analyzer yet. With all of 
the bandpass filtering in the LO system and elsewhere in the rig, I 
doubt that much of the VFO or XTAL OSC could be radiated.

I put all the covers back on, and did not lose a single screw, or end up 
with any extras.

I made my first QSO with the rig tonight, since the repair, and got good 
reports.

I suppose a trip to Sevierville and back, and repair there, may have 
been quicker than fixing it myself. It certainly would have cost more, 
and I would not have learned as much about the rig.

It is good to have it back on the air.
