Roelof - sounds good - we are about 1000Kms South of PVQ here in South Cent= ral Alaska and Im sure your going to get good responses about getting into = the night side ionosphere about 1400Kms from Amsterdam on that Rhum line&nb= sp=3B bearing but the sun is pretty low too so prob absorption is pretty lo= w (perhaps - Ill leave it to the experts!) - however with the K at level an= d the location of the Auroral oval its going to be interesting -

We = had experiences on interesting paths (more VHF and HF than LF) on being<= b> inside the auroral oval during highly disturbed periods - I was = at Ward Hunt Island at 83N in March 89 (or was it 86!) on =3B North Pol= e expedition when a very large Geo storm hit - had me dismanting connectors= and checking the Front end of the Military transmitters it was so so quiet= . It was like being in a goldfish bowl - comms inside were actually very go= od=2C but very weak for pass crossing out and across the Oval to the South = (its all to the South just about) - one way traffic or the "diode effect" I= called it.

Just to let you know the Pa0rdt probe continues to work = very well up there - its within a dB of the main 2 element K9AY on quiet da= ys at 137 and sometimes does better - its odd to compare a small piece of c= opper clad to something that covers 0.5 acre but there you go - all very lo= cation and angle dependent of course.

>=3B Hello Laurence=2C
>=3B <= br>>=3B Maybe this is a bit of topic=2C but this week we found a new wind= ow for
>=3B listening to NDB's from Alaska.
>=3B PVQ-376=2C Put= River Deadhorse=2C has been heard in the UK as early as 14:30
>=3B = UTC.
>=3B A little later it faded out in the UK and was heard with a s= trong signal
>=3B in Normandy.
>=3B LUR-385=2C Cape Lisburne wa= s also heard in Normandy in the afternoon here=2C
>=3B around 15:30 = UTC.
>=3B Though just 200 km to the east=2C I could not hear these sig= nals.
>=3B Last night PVQ-376 was incredible strong for hours starting= at 03:00 UTC.
>=3B When I switched the radio on this afternoon=2C PVQ= -376 was already audible
>=3B and I listen to it while I type this.<= br>>=3B
>=3B Now a question for the propagation experts.
>=3B = At the time the aurora index was 5.
>=3B Should it be possible for the= se signals to pass over the pole=2C or is the
>=3B path probably alo= ng the border of the oval zone and along the Russian
>=3B Arctic Sea= coast and off the coast of Norway?
