  1. Follow-up to An Introduction to the Reverse Beacon Network(RBN) presented in Sept 2012Dave Duskin – NE5S

  2. Background RBN was created by Pete Smith, N4ZR RBN is hosted by dxwatch.com (PY1NB) CW Skimmer was developed by Alex Shovkoplyas, VE3NEA Aggregator developed by Dick Williams, W3OA

  3. What is CW Skimmer • Software developed by VE3NEA • Works with many SDRs • Decodes multiple CW signals in real time • Can monitor an entire CW band • Waterfall Display • Uses MASTER.DTA • Telnet Server (emulates a DX Cluster)

  4. Skimmer Server by VE3NEA • (more software) • Onlysupports the QS1R SDR • Decodes multiple CW signals in real time • Monitorsmultiple bands with single SDR • NoWaterfall Display • NoMASTER.DTA • Telnet Server

  5. What is the Reverse Beacon Network? • • Originated and operated by PY1NB • • Uses any decoded CW signal as a beacon • • Multiple Skimmers world-wide decode your • callsign, sending speed and S/N ratio • • An “Aggregator” program forwards Skimmer spots • to a central server • • Central server distributes spots via • www.reversebeacon.net, and public telnet servers

  6. RBN Feeds At any time there are approximately 90 skimmer stations reporting to the RBN – up from 70 in Sept 2012 NE5S is the only CW Skimmer station reporting to the RBN in 5-land

  7. NE5S RBN Feed Perseus SDR owned by Darell Brehm – WA3OPY CW Skimmer licensed to Darell Brehm – WA3OPY Currently running from the OCAPA Club station here at the Salvation Army Citadel

  8. NE5S RBN Feed

  9. CQWW CW – Nov 2012NE5S feeds to the RBN 23/1743Z – 24/1222Z – NE5S reported 2374 spots in 18 hours and 22 minutes 558 unique prefixes Only reported the first 22 KHz of 20M CW Band

  10. ACKNOWLEDGEMENTS • Perseus SDR - Darell Brehm, WA3OPY • CW Skimmer – Darell Brehm, WA3OPY • Computer setup – Steve Duskin, NE5SD • CW Skimmer & Briefing Support – Bob • Wilson , N6TV • Configuration Settings – Tim Duffy, K3LR

  12. Late Breaking News • WA3OPY’s QS1R will be up and running shortly feeding 160M, 80M, 40M & 30M spots to the RBN from 5-land. • QS1R SDR • Pixel Pro II Shielded Magnetic Loop Ant. • PC, Skimmer Server & Aggregator S/W How to be easily spotted by a CW How to be easily spotted by a CW How to be easily spotted by a CW Skimmer Skimmer Skimmer • Send everything at the same consistent speed • Send everything at the same consistent speed • Send everything at the same consistent speed – Do not use +++/--- or >/< to speed up/slow down – Do not use +++/--- or >/< to speed up/slow down – Do not use +++/--- or >/< to speed up/slow down • Call CQ or TEST and send your call twice • Call CQ or TEST and send your call twice • Call CQ or TEST and send your call twice – CQ N6TV N6TV – CQ N6TV N6TV – CQ N6TV N6TV • Use proper spacing (let computer send) • Use proper spacing (let computer send) • Use proper spacing (let computer send) – Don’t send by hand and rusheverythingtogether – Don’t send by hand and rusheverythingtogether – Don’t send by hand and rusheverythingtogether • Change freq. slightly to get spotted again • Change freq. slightly to get spotted again • Change freq. slightly to get spotted again
