Mike,

It seems to me that the bandwidth calculations given for CW are based
on 'true' CW - that is, carrier on / off operation.

I wonder if W1AW pre-records their CW material in audio format, then
broadcasts it as a modulated SSB signal - would that not stretch the
signal bandwidth out considerably?

Anyone know if this might be the case?

I've done enough post testing on this to be pretty sure that it isn't
me though.

The Waterfall screen in Digipan functions pretty nicely as a poor man's
analyzer. The signal was putting "crap" all over the place.

I wasn't the only person who noticed the problem.

I was not able to duplicate anything like the problem with the RTTY
contest, which had many strong signals, and should have been worse if my
reciever was overloading. I'm impressed with how nicely the old 745
performs.

The problem - whatever it was - was in the W1AW signal.
