Freq: 18.155MHz
I heard an OTHR radar system today that had a different sound to the
usual suspects.
It sounds more like the Iranian system 2 but not quite.
Maybe it's a variant they're using ?
Propagation analysis shows that 18Mhz would be open to Iran to my QTH
with two F2 hops, however the first hop would be in Cyprus, also a known OTHR
QTH that is "friendly to the west".
Spectrum analysis here shows a closest match to Iran System 2.
Some useful soundfiles to aid indentification are available from:-
www.iarums-r1.org/iarums/sound/main.html
and it's also worth looking at the links to other IARU MS region websites too.
