Well said, Craig. You don't use a 1.8 kHz filter because it sounds good! You
use it because you can't pull the station through using a wider bandwidth
due to close-in QRM and/or weak signal strength. You choose the bandwidth
necessary to copy the station you're trying to work.

If you're a casual operator or ragchewer, not really into contesting, DXing,
or weak-signal work on VHF, the 1.8 and 2.3 kHz filters are probably not for
you.

As I write this, I'm in QSO with a station in northern New York on
double-hop sporadic-E on 6 meters. He's getting weaker as the band changes,
and there is a lot of adjacent QRM. I'm now running 1.5 kHz bandwidth with
FC set to 1.00. Solid copy all the way, just signed with him and completed
the QSO before the band took us out.

Love this radio!
