[Elecraft] PSK31 on my K3

[Alan D. Wilcox]

Garry,

By way of "filling in the holes" as you said:
A couple years ago I wrote about setting up my K3 for PSK31. See
http://wilcoxengineering.com/projects/amateur-projects/24-configure-the-k3-for-psk31

One of these days I need to revisit the whole issue. In my spare time! hi.

73, Alan
