Arnie -
Tnx for your reply.

With menu 7-7 setting "cu r"  "oFF" the noise actually seems to be=20
less.  Perhaps this is because
the CW tone stands out more from whatever noise is present.  A better
s/n ratio.  I have the INRAD 70mhz if amp mod that is supposed to reduce=20
the if noise.

The difference also seems most noticeable with the EDSP narrow CW bandpass=
=20
settings.  Oh well.
Just use it and have fun!
