Mark,
Thanks for your report, I'm glad to hear that my signal is still
traveling your way. I just checked the WM lowfer meters and from my
end, the juices going in to the beacon are normal. Our weather here has
warmed the past couple days, the snow is gone, and ground has thawed. I
may have more ground losses than a few days ago when everything was frozen.
