[TenTec] Omni VI Frequency Adjustment

[Bob McGraw - K4TAX]

Start by checking and adjusting the BFO frequencies.  These must be correct 
first.  Then on to the master oscillator.

The procedure is outlined in detail in the manual.  Do follow the exact 
sequence as listed in the manual and don't skip any steps or perform them 
out of order.

Well after further examination this is NOT where I need to be - hi. It looks 
like that is the locking crystal for all the "logic" - duh!

More serious examination is in order!
