[Elecraft] [K3] Possible bad file in 4.67 ZIP archive

[Tom H Childers]

Downloaded and installed this morning.

I see no problems, and yes I saw the hmcu0467b.hex, but I'm not a bit
worried about it.  My machine and rig working great on my wonderful
Win 7.0 Pro SP1 machine.

Let's start giving Mr. Uda his due.
The Yagi antenna was designed by 
Mr. Yagi AND Mr. Uda.  It should 
be called the "Yagi-Uda" antenna.
