[Elecraft] K3 software utility needed

[Larry Phipps]

LP-Bridge allows simultaneous polling (GET) commands from 5 applications 
at the same time with no limitations. The only possible issue is 
multiple SET commands at the same time, which is an unlikely occurrence. 
The traffic to/from the K3 is almost constant, regardless of the number 
of applications requesting data.

73,
