Stefan,

It must be difficult to run such a high frequency transmitter when you= can't hear the loading coil singing!

The reports w= ere from my site in Maine. I was surprised to see them last night, as there w= ere strong thunderstorms about 200 km to the north, and the static was loud.=  

And you and Roelof are certainly correct tha= t the underlying TA propagation is year-round. Increased noise is a limiting= factor in the warmer months, as are the shorter dark periods. Surface wave p= ropagation over land is better in the colder weather. The effects of solar w= eather dominate this path in all seasons, though.

Thanks for providing the signals. I'll do some modest-power transmittin= g from the Maine site in the next month, once I have a suitable tuning netwo= rk for the loop.
