p.s One station that was omitted from my list
of UNIDs was an Arabic -speaking station on 4789.4. However, I later
discovered myself it was BSKSA Second Arabic programme on 7th harmonic from
684 kHz.
Penti,
In my opionion you are wrong on
this one. The 60m band is a subharmonic (half the fundamental frequency) .If
you listen on 2x4789.4 = 9578.8 kHz, you will hear the fundamental
frequency. However, normally I only get a weak signal here (just carrier
detectable, sometimes a little audio). Of course there is the
possibility that the 31 m band frequency is also a harmonic....
The best way to check this would
be to check 684. When my
mathematics are right : 4789.4/7 = 684.2 kHz. This off-frequency signal
should be quite easy to detect.
