Thank you, Dom....I've been wracking my poor memory wondering who had written that article..
But I do remember very well "when we had a 2.4 hamsat downlink", that if I couldn't "hear" the sun I knew something needed attention in my system!! And wouldn't bother to listen....
About this matter the best I can suggest is to read the following articles:
"Noise Temperature,Antenna Temperature and Sun Noise " by Bob Atkins, KA1GT
"Microwave Systems Calibration Using the Sun and Moon" by David B. Shaffer, W8MIF
Both articles are published in the ARRL UHF/Microwave Experimenter's Manual ARRL Order No. 3126

Pulling for P3E...
