SDR Notes

12 Dec

I would like to capture here a set  notes viz SDR Web Resources Net. In a sense this resource already exists in the form of an RBN or Reverse Beacon Network or in a stretch WSPR. However, there are some features within RBN that make it clumsy as a resource for antenna experimenters. This stuff may have been thought of prior to my scribblings but in case they had not I wish to capture them here so as not to lose any thoughts and perhaps stir up something if anyone believes this idea has merit.

  • I would like to be able to use an internet connection to grab an sdr receiver at a remote site and watch my own signal via S Meter and direct measure from a remote pan display, and read my signal strength at the remote site in DBm.
  • It would be nice to see this at multiple geographic locations around widely disparate locales.
  • scheduled windows of use.
  • networked resources (smart chart?).
  • standardized receive antenna to keep measures relevant? (Dipole or Probe).

The whole idea here is to produce a feature or set of features that would allow comparisons of antennas on a single site to remote locales a meaningful signal report. Or perhaps a pair of signals from a specific locale (say you and your buddy locally) to a remote site a comparison signal report. RBN requires a sequence of code be transmitted….say CQ de Callsign. This proposal would require non of that. Just grab the on line resource or schedule a time and then grab it via internet and run your tests. Something would of course need be done to prevent locking up the set of tools for extended periods of time but that would be an easy piece of code to produce.

All of this may be nonsense, however it provides empirical proofs to antenna designs and offers up an actual figure of merit (finally) to allow one to steer scarce resources into the correct elements of station design when design goals for antenna systems have been met.

Thanks for reading my Blog. Best, Chas W5PG

    Check out this site: http://www.websdr.org/
    It may do some of the things you mentioned. I was able to listen to my qrp signal
    to the sdr receiver in Walla Walla WA on 40M. There are several sdr receivers on line
    around the world. Fun to play with. Cheers, Gary KF6U
