[Elecraft] Reflector: K3 Roofing Filters

[Ray Coles]

Since this subject is current (and likely always will be!) I have to ask the
learned brethren which filter does experience show to be best for use with
JT65 mode. I currently only have the standard issue 2.7KHz filter, which of
course works OK for everything (except I suppose DSB and FM). If I used CW I
would definitely choose a narrow-band filter, but the waterfall display used
for JT65, PSK31 etc. might lead me to rely on a 2-3KHz filter for these
modes, even though the signal bandwidths are much narrower. My question is:
is anyone using narrower roofing filters and tuning across the waterfall to
squeeze the most out of those DX data stations? Or am I being dumb?
