[Elecraft] [K3] Issue with HI CUR on 12m

[Bill Coleman]

Isn’t the name apt, though?

A feedpoint choke like this does manage the interface from the unbalanced coax to the balanced antenna by inhibiting the flow of common-mode currents. Hence, Bal-Un.

Agree that the term is insufficiently descriptive.
