[Elecraft] K3: FSK-D vs AFSK

[Jim Miller]

I played a bit with FSK-D and AFSK today. I was able to get FSK-D to decode
and display on the PC via the K3 Utility Terminal tab.

While listening to T32C working a split RTTY pack I realized that trying to
figure out which was the most recent worked station was a bit more difficult
than doing it for CW, especially since the UP distance was 8-9Khz.

I thought AFSK and display of the sigs on the PC screen might be of benefit
but after putting it all together I realized that the bandwidth of the audio
out would limit the spectrum to less than 4Khz.

So what's the benefit of AFSK over FSK-D?

Any suggestions for finding the last station worked in a pack?

TIA
