[10gigs] [10ghzcontest] W0AUS beacon report

[Gedas]

Chris, I found your report most interesting and valuable. When you 
mentioned a very strong signal all but disappearing when looking through 
a modern glass sliding door that was a bit of a shock ! I suspect the 
glass has coatings for reflecting uV radiation and this also may be 
affecting uW signals. Thanks !

Light travels faster than sound....
This is why some people appear bright until you hear them speak.

I was pointing generally in his direction looking out over the balcony with the dish/tripod just inside the apartment.

Perhaps the attenuation is less significant under those circumstances?  Possibly worth further experimentation.

>> Hearing the W0AUS/B now.  Started light snowing here about 30 minutes ago.  Direct path, pretty weak, but 50% CW copy.  Good for a Q !  About 53 km over the hills and through the woods.
