Pete and others,
Based upon your experience and others I have purchased a QS1R with an
expected delivery this week.
I'd really appreciate you taking a few minutes to describe any special
configuration you needed to have it work across 7 bands with CWSkimmer
Server. I don't want to have to discover all your lessons learned myself. It
will be used solely in this role.
I plan to use a dedicated receive antenna (vertical) with a receiver front
end overload protector (I.C.E.) before going into the QS1R. I'll use it on a
stand-alone computer which is a quad core with 2 GB of RAM running Windows
XP Pro latest SP.
Thank you in advance for any tips or lessons learned you have.
Mack de WB4MAK

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
73, Pete N4ZR
