Who's going to be first to work WAS on 630-meters? Propagation is there for most, perhaps all, of the country, however a few states, including my own, still lack hams with transmitting capability.
KL7L is quite active running 5 watts on various modes. He has a good signal that often makes it to Australia and Japan over the easy salt water paths. To mainland US his range is usually limited to the Pacific Northwest. A day ago I decoded his WSPR beacon for the first time. As you can see below, it was quite an opening that extended deep into the midwest and even to K4SV in western NC.
Merv, K9FD/KH6 is easy from most of the country. He runs one watt from an exceptional location, a former broadcast site right on the Pacific. He has been off the air for several weeks, but this morning I picked up his signal again.
