Mike,

You're received a number of good answers. As for measuring bandwidth, I've
used exactly two receivers that would be suitable for accurate measurement,
and I couldn't afford either of them. With stability measured in 10 to the
9th power and accuracy at 10 to the 8th, these little babes were well over
$50,000 in the mid 90s. LOL. Oh, and that doesn't include the cost of the
IF spectrum analyser that was connected to one of them, nor any other costs
such as calibrated antennas.

As stated, the rise and fall times of the waveform determine the bandwidth;
often the receiver can deceive you as to what the bandwidth is.

Of course, it is possible there may have been a problem at W1AW.

The question kind of states it. I suppose that the BW might be wider as
the speed increases.

The reason I ask is that on 3580 tonight, we're all sitting there fat,
dumb, and happy, when W1AW starts it's CW broadcast. And it's some 700
kHz wide!!! And now I'd swear it's almost 3kHz wide. That's like SSB!!!

Needless to say, their strong signal was pretty tough on all us 5 and
ten watters. you could get most of a message through, but it took a lt
of the fun out of it.

What the heck , over?
