I have to disagree. I had one, and the bandwidth of the filter used is 
so wide that it's impossible to distinguish cw signals a few kHz apart. 
It definitely does not provide the kind of display found, for example, 
on newer ICOM rigs.

I too would like a standalone panadapter (bandscope, whatever) that does 
not require a computer, but I don't miss the Kenwood unit.
