[Elecraft] View frequency spectrum easily - CW on K3, etc

[Alan D. Wilcox]

Hello,
A frequency spectrum display showing 5, 10, 20 kHz would be nice, but I 
found that a simple display of my passband's several kHz can be quite 
useful ... especially when I want to dial in the K3's manual notch on 
some interfering target.

The idea is to simply use a waterfall display ... for CW.

I use Ham Radio Deluxe (HRD) latest beta and run DM780 from there to get 
a waterfall. The K3's CWT feature is nice to center on 600 Hz, but I can 
instantly see not only the desired CW signal at 600, but also see other 
CW signals nearby. This makes it easy to set the passband as well as 
null out the junk.

And here's a plus: DM780 does a fairly decent job of decoding CW. 
Perfect with ARRL, but that's another story! So for me, trying to get my 
copy speed up again, having a backup display (even if it's garbled) can 
perhaps fill in some gaps for me.

Useful idea? Comments?

Cheers,
Alan
