[Elecraft] K2 relay circuit?

[Tom Hammond]

AMPKEYKIT is only a few components.

With luck it will be replaced SOON (Hint: Eric) by a real PC board 
and all components, including a set of INSTRUCTIONS.

Elecraft has all the info (PC board layout and draft instructions, 
but has been too busy thru the Xmas season to move on it.

Until that time, I can supply PC boards ($6 ppd to your US mailbox), 
and components are available from Mouser for a small cost. Shipping 
costs more than parts.

Docs (PDF) upon request.
