[Elecraft] 1.8 or 2.1 kc Filter

[Brett Howard]

Personally I really liked the 1.8K filter in my rig during FD.  The
bands were packed and they'd allow you to squeeze into the tightest of
places and take a run freq that you know the guy above and below you is
being bugged by people calling you back but you can pick them out of the
muck like magic.  With judicious use of the shift knob you can center
around the frequencies needed for intelligibility and you get all the
frequencies that you need and ignore those that you don't.  But you do
need to be a lil ready to use RIT though..
