Based on feedback received, I've re-recorded the demo of CW Skimmer at PJ2T
during the 2009 CQWW 160 CW Contest to include audio. The description is
[VIEWING FULL-SCREEN RECOMMENDED]
A demonstration of CW Skimmer, recorded during the 2009 CQWW 160 CW Contest
at the PJ2T contest station on Curacao in the Southern Caribbean during
sunrise in Central Europe. The receiver was a RFSPACE SDR-IQ and the antenna
was a 1000-foot Europe Beverage.
On the left is the Writelog Bandmap window, to the right are the CW Skimmer
windows. This shows the spots made by CW Skimmer in just 2minutes 47
seconds, as if the receiver and CW Skimmer were first started at the
beginning of the period shown. These spots were captured even while PJ2T was
calling CQ and working stations (as you can see in the overload on the right
window and hear in the audio).
During the recording of the video, I selected some spotted stations on the
CW Skimmer screen: DL1AUZ, MD4K, G4BJ, YU1LA, and PJ2T. This shows how even
today, 4+ years later, I can listen in on any station in the recorded 192
KHz bandwidth of the CW Skimmer recording made in 2009! this is the
technology in use by contest sponsors now to check operations of top scorers
and suspected cheaters.
A block diagram of the station configuration used during this 2009 contest
at PJ2T is shown at:
The Afreet CW Skimmer is an invaluable contest tool for the Multi-Operator
or Assisted class contester!
