[Elecraft] K3 rtty decode vs: computer decode

[Fred Jensen]

Yes, the K3 certainly allows a multitude of modes, and within each mode, 
several ways of doing it.

I'd really like to know ... no hidden aspersions here ... what the 
difference is between direct FSK and AFSK.  I use AFSK with two 
RadioShack stereo cables between the laptop and the radio.  N1MM with 
MMTTY for contests, or one of several other sound card-friendly programs 
for PSK and JT65 which I almost never use.

I'd really like to know, I'm not kidding and I'm not casting any 
aspersions on any technique.  My K3 provides for both, my AFSK seems to 
work great and when I look at my transmitted spectrum, it looks like FSK 
should look like.

And this has nothing to do with the number of cables behind the rig, the 
back of my rack is visible as you come into the "shack" and my wife has 
asked, "Why do you call it wireless?"
