[TenTec] Omni VI Frequency Stability

["Mark Erbaugh" <mark@microenh.com>]

As I recall, there were some changes in the methods to maintain frequency
stability with the Omni VI. I believe there was originally an oven. A later
mod left the oven on, even when the rig was off and a later mod involved a
TCXO.

I purchased a used Omni VI that had been factory upgraded to option 3. How
can I tell which version I have? I'm not sure I would know what a crystal
oven looked like unless it said 'Easy Bake' on it <g>.
