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 below.

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: http://www.k8nd.com/Radio/CW_Skimmer/PJ2T_CW_Skimmer_CQ160CW_2009.jpg . The Afreet CW Skimmer is an invaluable contest tool for the Multi-Operator or Assisted class contester! 73, Jeff K8ND _________________ Topband Reflector
