Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: Real k Factor values for West Africa

Does anyone out there have real measured
values of earth radius k factors valid for long
rf paths in West Africa?
Whilst there are available
formulas when you have humidity, temperature and
pressure profiles over the first 1000 meters of
height in the tropo, I am looking more for radio
measured values over real links.
I am getting
measured RF levels end-to-end on a VHF link of 100km
that are way below most software model predictions.
