[Elecraft] no receive update / CW mode

[glblock at mchsi.com]

I got my new RFC2 and installed it.  Man did this radio come alive.  Lots of
noise on some of the bands but I heard something on all of them.  I installed
the DSP unit, built that up while waiting for the replacement choke.  WOW the
noise went away and all kinds of folks out there, and that with 15 foot of wire
hanging off the desk.  I have to learn how to operate this unit tho.  When in
lower sideband and I come across a CW signal and switch to CW mode I lose the
signal.  So I move up and down the freq a few khz and its not there... move back
to sideband and there it is???
