RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Thanks
to Patricia W. for letting me know about this amazing website for obtaining
tropospheric ducting 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
William Hepburn's
DX Information
Centre. It provides a plethora of data including
6-day forecasts
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.
