[TenTec] TenTec Digest, Vol 184, Issue 16

[N4IJ]

I vaguely remember that the manual has an error in the adjustment
procedure. Someone on the list probably has the correction. I found it on
the web.
I tweeked mine using the corrected procedure and it still has more than 100
watts on a couple of bands.
My OMNI 6+ is sitting on the shelf. Trying to decide if I want to sell it
or not. Mighty fine CW.
