Background

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


Background

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


Background

  • 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)


Background

  • 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


Background

  • 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

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
