View frequency spectrum easily - CW on K3, etc
 
|
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 -- Alan D.

Yes, I have been using this technique for a while and find it very
useful. It is very helpful in finding "clear" spots for calling in a pile-up for example. I happen to be using HamScope 1.52, but any of this ilk will work.

Doug,
Now there's a thought! And instead of plain CW, I think that I can send (audio) CW at whatever waterfall frequency I select. Think it'll only work if I use the keyboard for generating the CW though. Copy by ear as usual, or just let HRD help out since I'm already at the same frequency. I'll try it out ... the spectrum display and easy QSY into an open niche. Thanks for the insight. Alan Alan D.
