Actually, I think the technical bulletin was implying that the transmitters
may sometimes be off frequency. Since I don't often monitor the air band, I
don't know if this is a common problem.

I have the same interest in the Collins filters because they have
steeper and, presumably, deeper skirts.

Re the air bands, I thought the AR8600MkII had the correct step
programming for that band. If you're "on frequency", there should be
no problem with the filters. The wider filters would be better if
you're "off frequency" because your radio is scanning with the wrong
step intervals.
