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

[Lee Buller]

How do you (the people who use FSK) key the radio through the RTTY program?  I 
am using AFSK and have good experiences, but I wonder how keying is done through 
the software.

 In our day and age it seems that Common Sense is in short supply.  If you don't 
have any Common Sense - get some Common Sense and use it.  If you can't find any 
Common Sense, ask for help from somebody who has some Common Sense.  Is Common 
Sense divine?

Common Sense is the image of the Creator expressing revealed truth in my mind.

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!
