[TenTec] Orion trim pot adjustment

[John Occhipinti]

Carl, after opening the Orion II from the bottom (removing the bottom 
cover), the master oscillator (TCXO, Temperature Compensated Crystal 
Oscillator ) is located on the A10 board and is marked with the brand name 
Siward. Use the smallest jewelers type screwdriver and adjust this just a 
little, as it is very sensitive. You do not need to use an insulated screw 
driver when adjusting this.

I have done this to my Orion II, as it was 50 Hz low when I bought it. I 
have the complete procedure if anyone needs it.

Carl, it was nice seeing yuo again last week at the Dayton Hamvention.
