[Elecraft] [K3] Built in USB interface for K3

[Guy Olinger K2AV]

Well, just as a single example, for bench scales which are connected
to a data processing device, see

http://www.scalesgalore.com/pindustry.htm

For those scales which have remoting as standard or an option, *some*
of them have optional USB, but ALL remotables have RS232.

RS232 very much alive in general industry.

73, Guy.
