Re: Fw: SUISAT forensics...The reverse procedure



Hi John, KD6OZH

I agree that Tsky is about twice the earth thermal noise level at 144 MHz
due only to galactic noise but Tsky increases also depending on the
suburban man-made noise and urban man-made noise as well with the
elevation of the antenna and estimating Tsky= 1200 kelvin is a good
choice for the average of 144 MHz EME stations.
