If the previous owner used a non Ten-Tec supply, they would have never  
known about the switch. It may be broken, or needs to be cleaned.

AFAIK, 28.5 only was the standard at the time. I really am only  
familar with the Trition Series, which did not have the WARC bands  
(which were not legal in the US when the Omni's were first out). The  
Triton I used to own and the one I have now both have all 10m  
crystals, but they were an option.

It's unfortunately an issue with all rigs of that age. There have been  
MANY discussions here and on other lists about using De-Oxit, and even  
videos on YouTube. The important point is to buy the liquid (not the  
spray) and using a drop on the end of a toothpick, place it on the  
contacts and rotate the switch several times.

The spray works well on some things, but wafer switches may be damaged  
by it.

It it's just the matter of a crystal, then you can find one on eBay or  
have it custom made. Custom crystals run between $20 and $45 depending  
upon who makes it and how quickly you need it.
