[Elecraft] A Different View--K3 Reduced-bandwidth RTTY Analysis

[Milt -- N5IA]

Since I am NOT a RTTY operator I am asking if this DSP software revision is 
applicable to other modes.

I would presume it is, but obviously not with the same type of cleanup 
required with the RTTY artefacts.

Please expand the conversation to include CW and SSB.

Thank you in advance.

de Milt, N5IA

Andy, K0SM has a very nice look at the K3 reduced-bandwidth FSK keying.
(Now available to all as Beta DSP rev. 2.8.)

It is also interesting to look at before and after FSK signals in the time
domain.

K3 FSK has always had a small amplitude difference between mark and space.
The transition has always been abrupt, Photo 1. With the new beta software,
the transition is much more gentle, Photo 2. Bravo!

Diddle Exuberantly,
