[Elecraft] CW QSO's from around the house

[John Watkins]

I know someone out there has thought of a good solution for what I would like to do.  Want to use my K2 in the shack from anywhere around the house and yard...say within 100 feet.
 
Listening to the receiver and sidetone is no problem with a wireless headphone set.  But, how to key the transmitter with some type of wireless paddle.  Has anyone done this and would like to pass on your approach?  Ideally, at the K2 end of the wireless paddle the device would simply plug into the key jack.
 
Thanks, John N0EVH
