Hi all, I have attempted to drag myself out of hibernation, and I have the
new plots from Brian CT1DRP on my web site. I will hope to update this
regularly (daily?) again. I have no excuse as Brian has set up an excellent
system for automatically posting the data to me. You will notice that in the
rebuild, the levels on the plots have changed somewhat. This is due to
tuning DCF39 into the passband. You will find there is a 17.5dB difference
from the older plots, but the "benchmark"  average line based on 20 days of
September 2001 has been adjusted. So above the line is good and below poor.
All of the January plots (.GIF files) are available as a zipped file (140kB)
on my web site "programs area" as a file download.

The link from the "hot button" on Daves G3YXM's site is still active. I hope
soon to have some more data comparing Brian's plots with Steve and Dexter's.
The present poor night-time conditions are evident on all the plots. Dexters
real-time plots for last night show the DCF39 levels he receives as down by
nearly 20dB on the "good" nights in mid-January. Present poor night-time
conditions are expected to last another week or so. (sorry Ed !!)

Cheers de Alan G3NYK
