Hi Crawford, It's been a while since we last chatted - I believe the last time was when a gentleman said your book "The Friendly Ionosphere" supported his theory of NVIS propagation on 10m. I'm curio
Hi Carl, I'm afraid SnapMAX is just no help at all on that one. The IFRB etc. data gives me no basis in there for extrapolation. It's an empirical approach in which the data is all from the non-inter
For the past couple years I've been using some very useful propagation software called HF Prop by G4ILO. In September 2004 he put out an upgrade v1.4. The software shows current global daylight, gray

Crawford, Putting those field strengths into a -2dBi antenna (about the max gain of a vertical over average ground): 1uv/m at 4500km = -84dBm -20dB ref 1uv/m at 7000km = -104dBm -40dB ref 1uv/m at 10

Remember the X 28 flare on Nov 4, 2003? There was a fabulous video of it on one of the propagation sites. (HFRadio?) Tomorrow night I'm teaching propagation to my club's licence class and would love

Virtually all forecasts of solar maximum and minimum are incorrect. The average sunspot cycle is 11 years but it varies from 9 to 14 years and we still do not know why. So this variation ruins the be
If you monitor the PSK31 propagation beacons on 28120 kc you will find 10 meters open in some direction via Es or F2 virtually every day that there is no geomagnetic storming. 73, Thomas F. Giella, K
Tom, Steve doesn't give his email, but could you pass this to him? Steve, often at dawn/dusk with a signal at the opposite side of the earth (or near it) signals will flicker from SP to LP. W1EVT in
