[Elecraft] K3 firmware upgrade via Microham MKII

[Richard Thorne]

Thats the only bummer about he MKII. On my operating table its a bit of 
a challenge to have to swap out cables on the back of the rig.  I guess 
an extension off of the K3 could be made so one doesn't have to drag the 
rig out to make the change.
