[Elecraft] 20M sub receive

[Hank Garretson]

Also make sure your (contest-logging?) software is not causing the problem.
I had a spell, when for reasons I don't completely understand, SUB wasn't
working on forty meters. By chance I disconnected N1MM, which was in SO2V
configuration, and the problem went away. The problem had something to do
with conflict between N1MM and a homebrew external switching scheme.
