I'm also gratified to see that it is > of use . . . This is really a very useful site and I have contributed somewhat to w3eee.com hits. I guess this is an extension of the service that Alan provided when he monitored the station in Newfoundland but gives us a good idea of the propagation from a North American perspective. The ability of the display to monitor adjacent channels for electronic environment (squirglies) so that we get a fuller picture is very well thought out. The fact that it is in near real time is a real bonus and enables us to keep our powder dry until we have something to shoot at. >.... also amazed by the great propagation it captured last night. Yes, this seems nearly as good as the 'Scorcher' early this month. Acting on the information from KL1X in his e-mail of the 13/1/03, and from the strength of DFC39 on the w3eee site, I transmitted from 0600 until 0900 on 137769kHz. I will have to wait until 3rd Feb to know if this was successful. (The 'Scorcher' at w3eee coincided with large strength EU B/C station signal strengths in Alaska). I don't think I will be transmitting tonight. Gale force winds and driving rain make putting up the antenna just a tad too exciting!

Yes, the 'top' sensitivity are probably more important than the bottom when trying to correlate DFC39 or other commercial stations with amateur stations in propagation studies.
