It seems to me that the old OMNI series radios can be repaired if you can
find a substitute part which can be made to work. The are no proprietary
chips or devices. Its pretty much WYSIWYG an analog PTO radio, just read the
schematic, look at the parts, find a replacement part which works, repair
the old part, or make a substitute.

I spent 3 hours on it, pulled front panel and then unsolder/pulled the pots.
I actually was able to pull them apart, and push the shaft in and out to get
it unstuck and then put some grease in and put them all back together and
make it work as new. Once you get the pot out not as hard as I thought. Only
problem, the S meter has some corrosion, and the fine wire is broke inside!
I was on my way to getting this trash can Omni back to life...Got the
speaker ps going last night..Now to just find a old S meter! Thank for
reply..Randy

Randy,
Those are very hard to find, some people ran 12V through the power switch
and burned them as there weren't designe for that current.
There were only meant to power the AC line to the power supply.
Best find any push/pull pot of any value then replace the resistor plate
with one that works or the original if not damaged.
I have a surplus store here that sells the 100 ohm version in the same body
style,
What I have done in the past is open the front of the 100 ohm one by lifting
the tabs and then replaced the carbon resistor plate with the correct value.
If you can't use the original plate, Make sure you find the right type of
resistor plate, there is a audio taper and a linear taper.
Hope that help.
Best Wishes
Richard

I picked up a neglected Omni C with matching supply/speaker this weekend
at Hamfest. Lots of oxidation/ rust on bolts on inside. I free'd up most
pots, but the push on/off with pots --don't move in or out. Anyone got
any spare's they want to part with? Randy K5SL
