[Elecraft] Pro II like scope on K2/100 with a PC?

Nope - you never discourage me George - you just come up with interesting ideas. Now out of curiosity (hi hi)you said the question is why? So why did YOU link the scope to the K2 George (tongue in cheek, but now I'm curious). Knowing you I expect the answer will be similar to: Because it was there! Thanks George. 73/Tim NZ7C
