There is a cool new Yahoo group (I'm not the moderator, just spreading
the news). It is kinda of a quick reaction type page for shortwave
afficianados. The moderator puts up a couple stations with times and
frequencies to focus on for three or four days and those who wish to
participate post their results along with location and radio set up.

Check it out and see if it is for you. I think it is one of the best
ideas for a shortwave group in a long time.
