A KiwiSDR Dynamic SNR Map

Many thanks to SWLing Post contributor, Mark Fahey, who shares the following comment in response to our KiwiSDR post from yesterday:

[T]here are now so many [KiwiSDR] receivers – how do you know which ones are best? Why not use this map as an alternative to sdr.hu/map:

[A]ll the same receivers are shown in a map interface but the receiver signal to noise ratio changes how big each receiver target appears. The bigger the blob, the better the lower the noise which usually equates to a better antenna system etc.


Wow!  Thanks for the excellent tip, Mark! This map makes exploring the KiwiSDR network much easier. I especially like the full screen option.

Note, too, that Mark hosts a KiwiSDR in Freemans Reach, Australia (near Sydney). Mark sets the default auto logout for 2 hours to better cater to SWLs (which he says only represents about 10% of his SDR guests!). Most KiwiSDRs use the 30 minute default auto logout, which I find frustrating when I’m making broadcast recordings.
