Right, the AP isn't directly at the client, but it says there's only 0.8 db
of loss due to that. It says I lose 7.4 dB due to obstruction (when I have
a 1.4 Fresnel zone) and 6.6 due to statistics.

Thanks for the info Brian!
It has taken me all of 45 years to figure out when to listen, when to shut
up and when to just "shut up and listen."
I appreciate (as I am sure anyone that struggles with getting RM setup) the
fine advice and direction you give.

And RM uses the terrain data to determine which Fresnal zones impact the
signal. Raise or lower one antenna in 1 m increments and see the
difference. Most of the other programs I have seen just use the
distance, they show different values than does RM.

Radio Mobile is not doing a simple free space loss calculation. There will
be a fade margin factored in based on the numbers you use for mode of
variability. If you open the path profile window then do a "view" "details"
you will get a text window that shows all the calculation details the

How do I figure out how Radio Mobile arrives at it's signal level? On a 3 km
link in 5 GHz, I'm off 15 - 20 db from Eje's power calculator. What the radio
link window says is really close to the input numbers for Eje's calculator.
Why they're different is that I actually used the right antenn
