Good suggestion, swap filter positions. If the problem stays with the 250
Hz position it is a switching issue. If it moves to the 500 Hz position it
is a filter issue.
Yes, the 250 Hz filter is very narrow and PBT is critical. I have both the
Omni VI+ and a Paragon with 500 Hz and 250 Hz filters. Same on both rigs.
