[Elecraft] KX3 whip antenna and paddle

[Wayne Burdick]

The BNC will support a lightweight whip. The jack is attached directly  
to the chassis, not to a PC board.

Of course you could rig up a different type of whip, perhaps bolted to  
the long edge of the case.

My preference for operating while walking would be to put the KX3 in a  
very small backpack with integrated antenna support and a larger  
battery. The KX3 could be turned on/off and fully controlled from a  
hypothetical super-mic that includes a display and speaker. No plans  
to make such mic yet, but the design supports it.
