Many thanks to SWLing Post<\/em> contributor, Mark Fahey, who shares the following comment in response to our KiwiSDR post from yesterday<\/a>:<\/p>\n

[T]here are now so many [KiwiSDR] receivers \u2013 how do you know which ones are best? Why not use this map<\/a> as an alternative to sdr.hu\/map<\/a>:<\/p>\n

\"\"<\/a><\/p>\n

[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.<\/p>\n

Wow!\u00a0 Thanks for the excellent tip, Mark! This map makes exploring the KiwiSDR network much easier. I especially like the full screen option<\/a>.<\/p>\n

Note, too, that Mark hosts a KiwiSDR in Freemans Reach, Australia (near Sydney). Mark sets the default\u00a0auto 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.<\/p>\n
