Mike TTS,
Thanks for the capture of WM. It is still on the E-W loop. About noon
today I swapped batteries on it and tweaked the loop RF current back to
.95 A. That's about max for the RG6 Quad Shield. If I had RG8 size
copper, the current should be about double that. Too many $$$ involved
in that upgrade for a temporary test setup. I will be putting a graphic
WM back on the vertical in the next couple weeks. I want to try the loop
in receive mode for a few days before taking it down.
MM is just above your capture at 185304. The main purpose of MM was to
evict the bugs from the vertical until WM takes over.
