Re: LF: Who says MF TA is only possible in winter?

Stefan,

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

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

And you and Roelof are certainly correct that 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 propagation over land is better in the colder weather. The effects of solar weather dominate this path in all seasons, though. 

Thanks for providing the signals. I'll do some modest-power transmitting from the Maine site in the next month, once I have a suitable tuning network for the loop.

Hi MF,

Not bad at all i find...
