Hi Steve
13/1/03

Having just returned from a week long business trip to find that
w3eee.com was still working(!) 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!
(new pictures of G3LDO LF station and antenna on web site, see below)


As Alan has noted,  some traces show suspicious signs of the
measuring system clipping, or 'topping out';  this can be seen at
about the -8dB level on the !' trace, and at 0700z+ on
the present trace.

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.

Regards,
Peter, G3LDO
