[TowerTalk] Coax Stubs for SO2R

It has been a good while since I employed stubs on
an old BC-610.

Open stubs scared me because I was worried about a
voltage appearing at an open stub.  Besides, it is
a bit trickier to "tune" an open stub.

I went for a half wave shorted tuned to the second
harmonic.  No voltage threat plus is was simple to
tune it by pushing pins through the coax near the
final shorted end.  NO instruments needed other than
the S-meter on the adjacent receiver.
