Hi John, interesting.....thanks for the plug :-))  Good nights rarely occur 
when Dst is lower but are not guaranteed when it is at or higher than -20nT. 
I still haven't got a grip on that on the level of variation at high Dst.

I certainly remember playing AFRICAM with Larry. I still have one of Bill's 
sigma-delta ADCs here.though I didnt have GPS sync then. Brian CT1DRP ran 
GPS sync QRSS and DFCW using one of Andy's design synthersisers and some 
code I wrote to key it.  Then came WOLF.......no not he of the amazing 
technicolour Spectrum Lab.... the weak signal mode. :-))

Best Wishes
Alan
