[TenTec] Centering Orion II Roofing Filters

[Ron Castro]

I have an old 'boat anchor' signal generator that I use, but you can also 
use another rig running into a dummy load or a local ham you can hear on 
ground wave who can put out a dead carrier for a few seconds.  I found that 
no adjustment was needed, even on the 300 Hz filter.  After tweaking the 
settings, the defaults were still the best.
