Tom Stone of Hy-Gain wrote me that it did not sound like a heating problem
to him; he was thinking moisture in the LMR400 (a nightmare I considered) or
the matching unit; or, he said, a bad solder joint on the 40 meter coil.


I was sure I’d tested this on 20
but heck, haven’t been on 20 in a year
so I
called CQ for 15 minutes at 1.5KW out
the SWR did not budge.  These were
back-to-back (dead band) calls at 24 WPM; I know on 40 I’d have had trouble


Maybe it’s fixed
will drop it down.


73, and thanks for the schooling,
