Duh! This paper gives distance in kilometers; I was thinking miles. Teach me to read more carefully.

I just read through this and haven't researched it. Back in the dark ages when I was designing mirowave systems for 
a liviing, FSPL was given as 36.6 + 20 log D + 20 log f. This paper gives a different value. I don't know why, since the 
physical constants haven't changed, and maybe some day I'll look into it.
