[Moon-net] AMATEUR RADIO PROPAGATION STUDIES

[Volker (DF5AI)]

Dear fellow hams,

please find the latest update of the DF5AI.NET web site featuring

USING SATELLITE IMAGES IN SPORADIC E ANALYSES
In 2003 we have speculated about the generation of double hop dx  
propagation by reflection of radiowaves on the surface of major  
rivers and lakes. Having analysed 128 double hop events in 2006, we  
have obtained new results closing the case that was opened three  
years ago.

THUNDERSTORM EFFECTS ON SPORADIC E
The "Tropical Rainfall Measurement Mission (TRMM)" satellite shows a  
strong correlation between the ice content of clouds and the clouds'  
flash density. This results may have some importance on the  
prediction of sporadic E band openings. Actual storm forecasts may be  
obtained from a new internet service, i.e. the "European Storm  
Forecast Experiment (estofex)".

SCIENCE COMMUNITY ACKNOWLEDGES AMATEUR RADIO PROPAGATION STUDIES
The German section of U.R.S.I. (Union Radio-Scientifique  
Internationale) draws the scientists' interest on ham radio  
propagation studies.

HAM LINKS, SCIENCE LINKS, MONITOR WALLPAPERS, RADIO PROPAGATION  
ARTICLES, SOFTWARE REVIEWS etc. etc.
