With an Omni VI Plus and the 285 or 282 in line I always have to adjust the PBT control to about the 11:00 o'clock position. This is barely mentioned in the manual. Maybe one of the technical guys on this list can explain it. Anyway, try it before replacing an expensive filter.

I am a new owner of an OMNI VI Option 3. In the 6.3mHz Passband IF I have installed a #288 1.8hz filter a #285 500hz filter and a #282 250hz filter. When I tune to a CW signal I tune to the tonal frequency heard when you press the CW key in. When I have the radio zeroed in on the CW signal I hear the signal fine with the 2.4, 1.8 and 500hz filters but when I switch to the 250 hz filter the signal goes way down in strength and volume. In order to bring the signal back up to the level present in the 500 hz filter I must tune the receiver higher say from 7.040.00 to 7.40.20. The filters center seems to be too high. Can this be adjusted inside the radio or has the filter drifted and needs to be replaced?
Thanks for the newbe question. If I have not been clear about the problem please let me know.  73
