to Patricia W. for letting me know about this amazing website for obtaining
conditions and predictions. Patricia originally
wrote to me asking if I knew of any resources for ducting information
since she had a customer who suspected it was the cause of some transmission
problems. I suggested she check with the ARRL folks but although she
couldn't find any ducting info on the ARRL.org website, she did locate
. It provides a plethora of data including
of VHF, UHF & microwave radio and TV signal strength and interference.
So, ultimately she ended up helping me... and you if you ever need to
know about tropospheric ducting.
