Whew, the last week or so has shown changes in the regular morning HF propagation. At 1200Z I usually check into the Waterway Radio and Cruising Club net on 7268kHz. During the winter WA6CCA near Washington, DC (~44km away) is usually loud but now I haven't been able to hear him at all. ND7K down in Marathon, Florida is now the strongest shore station on the net at a distance of ~1618km.
I'm not sure I've taken notice of a condition change on 20-meters but W5WAZ, roughly 1985km away, on 14300kHz usually has a pretty good signal into Maryland during his shift on the Intercon net.
We'll have to see how things change as we move into the Summer months.
