[TenTec] Omni C (Model 546C) front end...

[Dave Plews]

Hi Jerry,  I'm not sure what happened to it.  It's been dormant for a long 
time and I took it out of storage.  Played with it a bit and noted that the 
sensitivity wasn't nearly as good as it should especially on 10 Mhz.  A few 
weeks went by and the digital readouts started acting up.  The receiver 
worked fine by lost the frequency LEDs as I recall on 7 Mhz, 14 Mhz and I 
think 28 Mhz.  The PTO needed a rebuild, too.  So I decided to have Ten Tec 
repair take a look at it.  They identified the sensitivity issue relating to 
the L1 coil on the RF amp board.
Now the sensitivity is bad on 160 - 30 meters.  It seems to play okay on the 
high frequencies.  I just wanted to get it working as a back rig for Field 
Day if I could.  As the problems became many I decided to take the leap.  I 
think I've leaped too far.
If someone had an Omni D parts rig, perhaps the RF amp board could be used 
in mine to have at least one good radio.
73, Dave...

What happened to it? Lightning? Stuck TR switch? Mouse? I don't have the
circuit handy but its likely a fairly common style of construction for
Tentec. Very likely another input coil from another band or radio could
be adapted, the mounting is the most difficult part of the problem,
Taking off or adding turns isn't a big problem.
