Had to try 2-3 times before the link worked. Not sure if that was a local connection issue or something else.
On another note, isn't 6200 kHz to 6525 kHz the 6 MHz marine mobile band for USB voice and various data modes? Yes, 5900 kHz to 6200 kHz is the busy 49 meter broadcast band so it makes sense for Europirates to hang out right above the band edge...
I know the 6200 to 6400 kHz range is popular for pirates regardless...not to mention North Korean shortwave broadcasts on 6400 kHz! Either way, this is some interesting reading.
Would be interesting to see it done for the 6765 to 7000 kHz range for 43 meters and North American / South American pirates (and the pescadores/freebanders/radiotelephone link systems carrying Spanish and Portuguese language traffic - not to mention the New England fishermen often heard in this area...). I know the big ones (the double side band Link-11 signal that pops up around 6940 kHz and the wideband ute around 6925 kHz, as Chris mentioned, have already been "TDoA'ed" but there's a lot of other mystery stuff on 43 meters that I wouldn't mind knowing where it's coming from (aside from pirate broadcasters, of course
)
