I am trying to understand a problem with my newly purchased OMNI C. It was operating fine according to the person who sold it to me (and I believe him!). Upon arrival it seems that the PTO has no out
Check the E voltage at the PTO. If this voltage is not about 8 volts, the PTO is disabled. The E voltage is jumpered at the ACCESSORY jack on the rear panel. If it is not jumpered, the PTO will not h

Dear Joe This sounds encouraging but can you give me a bit more detail? The OMNI schematic doesn't indicate an E reference. The PTO block only has a few outputs (VFO out, VFO shift and OT). None of t

I was foolish enough to buy a "mint" Omni C that the PO claimed was working FB before sending it to me. Among other problems, it also displayed the IF frequency (9 MHz) for several bands. It's proble

What your seeing is the preset for the counter. The display is nothing more than a freq counter. If you have a scope or counter see what's going into the counter/display. If I recall there is a RCA p
Mike, The output of the Omni's PTO is routed to an RCA Phono Jack on the rear panel marked VFO OUT. There is another Jack marked VFO IN fright beside it. If you do not have an external VFO, then you
I think I may be able to help on this having spent a LOT of time inside the OMNI...adjust the thumbwheel POT on the mixer/vfo board--it will ensure you are sending enough signal to stay on freq and s

Dear Joe That's unfortunately right. The OMNI PTO circuitry does not have an Enable line. The Corsair does. Any other wisdom? Regards Mike K1PEV ** On 2/20/12 9:22 AM, "Joe" <joe@n4yg.com> wrote: ___

Dear Scott R23 is the level adjust pot on the Oscillator-mixer board. I think that's the one you are referring to. The manual only makes a passing reference to it when describing setting the balance
Well Mike, I guess the next thing to do is to see if there is anything coming out of the PTO. You could use one of the scopes that everyone has been talking about or an RF probe. It is looking like t
Just a thought. If the pto is fubar, the rig would be an excellent candidate for one of the DDS upgrades. Mike wb8vge Sent from my iPhone _______________________________________________ TenTec mailin
Its been at least twenty years since I sold my OMNI-C and replaced it with the CORSAIR-II still on my operating desk. Both radios were ordered with external VFOs but were occasionally run with out an

Yes, thats the one...you should then see it go back on freq and not just reading the counter presets...I am at the rig now and just confirmed... scott va3ied _________________________________________
