Hi!
I hope It may be helpful.
For the best result you can to use Spectrogram and any
HF-ocsillator. With HF-oscillator (XG1 f.e.) you can
search max. peak of X.FILTER, best S/N and bands
filters levels.
Run Spectrogram
Turn On an oscillator
Find oscillator signal (turn VFO)
Tune for "Zero beat" in CW mode (hold "SPOT")
Run Cal Fil
Select FL1
Tap "BAND -"
Now you can to change BFO in small range(!!!) and
you'll see the max. peak of signal.
Another filters I calibrated using methods from N0SS
and Don Wilhelm. My MNI TNX for both OM!!!
Visit N0SS's web-site for download a Spectrogram
program.
