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.
