Hi Roelof, at night that is probably two hop for the main path though =
there will be some one-hop in the mix. Max LF/MF range upper =
D-region/lower E-region say 100km altitude is about 2500km by simple =
geometry. There is probably some lower level of 3-hop as well.

Best Wishes
Alan G3NYK

  Hello Laurens,


  Yes, location seems to be the most important factor.
  I am living 10 km from the coast and have e.g. a 2200 km unblocked sea =
path to Jan Mayen.


  Regarding Alert, it is just 4000 km away and a single hop I guess.
  When the band is quiet, I can hear it here at local noon in January.
  The grey line is than just north of Iceland, about midway between my =
location and Alert.
  It is quite easy to hear it here, however the guys in the US have the =
greatest difficulties.
  One reason is that most folks live far more south than here in Europe =
and hence high latitude stations are a problem.
  The other reason is powerhouse YQ-305, Churchill/Eastern Creek, CAN =
MB, that dominates the channel.
  I can often receive both at my sunrise and though only 6 Hz apart, =
aural single signal copy is no problem.


  Regarding ICW on 525 kHz, I have heard it only once  and that was on =
November 7, 2009.
  At the time LF conditions were truly awesome, with a solar flux of 68!


  On an other note the first NDB's from Newfoundland are already coming =
in here.
  So it might be a good night receiving for Joe's, VO1NA,  signal.


  73,
  Roelof, PA0RDT
