Look at the doc file I sent you about the Omni V.9
There is a software procedure to calibrate the Omni V.9
to make it perfect for each band.
Crystal Calibration Mode -
There is now a way to correct for crystal aging. To calibrate
a specific band, proceed as follows:
1) Tune to the band and frequency of the known source signal.
Mtune must be off for this procedure.
2) Tune the dial to read the exact frequency desired.
3) Press SHIFT TUNE.
4) Tune the signal in as accurately as possible. The display
should not change while you are tuning. Take care to not
tune the dial any more than is necessary.
5) When the signal is properly tuned, Press ENTER. This will
exit the crystal calibrate procedure.
