LF observations 17 Nov 1999 (136..137 kHz) by OH2LX
(qth: Jokela, South Finland, KP20LN, (60N34 024E58):
1915 OH3LYG (429) calling OZ1KMR (?)
2210 SM6PXJ (219) calling somebody (?)
2216 OH1TN (429) calling IK5ZPV (1-219)
(yes I definitely hrd IK5ZPV with
AR7030Plus/---- 10m coax---/1:10/---15m wire-----
-------------------------------------------------------
Ionospheric Cross Modulation (ICM) on DCF39 138.83:
ICM (modulation) hrd on DCF39 belongs to new LF station
Solec Kujawski 225 kHz replacing Warszawa-Raszyn since
24 Sept 1999; 1000 kW and two masts (289 & 330 m high).
ICM not as strong as that caused by Warszawa-Gabin
"super-station" (645.38 m mast collapsed on 8 Aug 1991).
Below 138.83 there is audible a mix of unintelligible
voice (S. Kujawski?) plus DCF39 "ghost burst" gradually
disappearing towards lower frequencies (REF: GW4ALG&G3XVD)
-----------------------------------------------------------
Leonids in Finland during morning of 18 Nov 1999:
Practically nil. OH9TEN 28267.5 kHz was audible though
around 0100 UTC with some notable "bursts" & "pings"...
Finnish FM TV DX people hrd occasional FM/TV bursts mostly
from Central European stations, a big disappointment...

I heard a very strange noise across the whole of the 136 kHz
band. It sounded rather like a mixture of cross-modulation/
inter-modulation plus Luxembourg Effect......

Yes, this has been clearly audible at various times this week, mainly
between 137.5 and DCF39. It was apparent last winter, too. I recall
discussion about whether or not this was really Luxemburg effect.
It certainly coincides with evidence of skywave on the various
commercial stations.
