Hello Jim!
Surely do appreciate the publicity - that sort of testimonial helps a
great deal.
I sent off one of my new keyers to the White House yesterday. I think
you will like it. Be sure to read the manual, particularly the tutorial.
The keyer will do a *lot*.
I think my biggest problem selling them is to convince people who own
radios with built in keyers that the K-3 goes far beyond the
capabilities of their built in, and is a lot more user friendly besides.
Anyhow, thanks again for the great comments.
