This past week I added RTTY and PSK to my station using Cocoa Modem, RUMlog, and a couple of audio cables from the Elecraft K3. Very simple setup with some spectacular capabilities in these fun digital modes.
One more upgrade to the ham shack. Last month it was a keyboard tray. This time it's a shelf to get the computer monitor directly above the Elecraft K3/P3.
There must be a rule that I've adopted --- nothing can be left alone, always adjusting and tweaking --- I'm sure it's an ethos of continuous improvement. But, if only it worked out that way!
