   Hello all, well I am a little embarassed this weekend....the cluster spots
   looks like my personal log! I guess the continental stations were deeply
   involved in Field Day, or else wiped out by noise.
   I suppose to be slightly useful I ought to declare my, less that optimum,
   receive set up. I am using a 16 turn 1.2m diameter loop made of multi-pair
   telephone cable. It tunes with about 650pF and is tapped at 2 turns with
   about 7 metres of 50 ohm coax to the receiver, which is an AOR 7030+
   fitted with a Collins 500Hz CW filter. The audio goes to a PC running
   Mike Cook's FFTDSP4 (prefered) or Hamview on a genuine Creative Labs SB16.
   (I found the on-motherboard SB16 emulator did strange things but almost
   worked ok with FFTDSP, but would not display with Hamview....both run
   under DOS5) There is the slightest sign of 70Hz scan harmonics on FFTDSP
   or 90Hz on Hamview. The machine that runs WIN95 totally destroys 136 so I
   dont run spectrogram, which is a pity. The loop is indoors at the moment
   and is orientated WNW/ESE. I could see a trace for DF2PY but he was just
   too weak for me to copy. (similarly with G3AQC...both Sunday)
   For my own purposes I have defined a 'measure' of the qrn in 'CPM' .....
   well  - Crashes per Minute! as counted on FFTDSP.
   Sat. was quite good at 1CPM from 0930Z to about 1400Z, when it rose to 5. It
   stayed between 3 and 6 through to 1630Z.
   Sunday started well at 1 at 0930Z but rose to 4 by 1027Z and 6 by 1046Z. It
   was up to 10 by 1100Z and 20 to 24 by 1200Z a sign of things to come later,
   I suppose, as the thermally generated storms brewed up.

 I hope that proves interesting, thanks to Wolf for breaking the monotony
 in the last column.
