I thought fellow Skimmerheads - and maybe some others - would be 
interested in some statistics from my Skimmer Server in the ARRLDXCW 
2010.  I was running a QS1R receiver on 6 bands simultaneously, with 96 
KHz bandwidth on each, and an 8-foot active vertical from Clifton 
Laboratories (mine is a prototype, but production units are now 
available - www.cliftonlaboratories.com ).  Incidentally, I never saw 
over 50 percent CPU loading on a very minimal dual-core Pentium.

In the 48 hours of the contest, Skimmer Server reported 46,954 spots, 
almost 1000/hour.  Of these, 28,634 were DX (non-W/VE) [note please, 
these sub-totals are approximate because I'm doing this manually].

On Saturday morning, the first European heard on 15M was 9A1A at 1140Z, 
8 dB above the noise; on Sunday it was 9A5X at 1142Z, 2 dB above the noise.

I would be curious to know how those compare with other US Eastern-half 
Skimmers.  My QS1R is sensitivity-limited on 15 and 10, because I don't 
(yet) have a preamp in line.  Did you hear your first Europeans earlier 
than I did?

Also, are there any hardcore Excel or Access jocks out there who would 
be interested in massaging the data?  If so I'd be glad to provide it in 
either form.
