[Elecraft] Elecraft Digest, Vol 105, Issue 14

I am wondering if anyone has used the k3 in any rtty contests and what
their menu settings are for the radio, thoughts comments, expectations
etc as opposed to all the greatness I hear on the y 5k reflector.
I know the K3 is a great radio but I don't seem to read too many
operator comments on its greatness......
thanks all.
Bill
