1. RE: QRPpp propagation on 10 MHz [was: [Propagation] PropagationReflector] (score: 1)

--Original Message-- I wonder if, even with your vertical antenna, that you are seeing NVIS propagation? The fading effect would be consistent with variations in electron density in the F2 layer over

Possibly because most propagation prediction programs are predicting low angle 'DX' propagation? If you want the local F2 Critical frequency (the one where signals go almost straight up and down, try

--Original Message-- That's the 'other' map on that site. :-) The problem always seems to me to be that it is 'DX' that many people concentrate on, when a lot of the paths most people actually use ar

--Original Message-- Be fair, the original question was something like "why are there lots of signals when the propagation prediction software says the band is dead". Maybe I misunderstood? Do you me

I have just heard GB3ORK at 07:47 UTC 3rd December 2004. Louder than either GB3RAL or GB3WES! I thought that I saw it earlier, as the G3PLX program was responding to something, and the classic 3 hump

Date: Wed, 8 Dec 2004 07:08:17 -0000
Whilst counting the number of 'steps' of signals heard from the UK 5MHz beacons I noticed something unusual happening. Normally the signals drop down into the noise after about 17:45UTC and don't nor

Thanks for the suggestions Thomas, Es seems a bit of a long shot, the signals were fairly consistent, and the only reason I didn't log them past 23:00 was that I went to bed. HI! What would cause the
