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


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


  • 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)


  • 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


  • 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


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


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


NE5S RBN Feed


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
