The sune is hugely bright in the RF. I've been able to see it at 2.2 GHz with nothing more than a horn a foot or so across and a receiver w/ a NF of maybe 8 dB (cavity preselector & mixer & IFA... ACL SR-209).
There was a noticable difference between pointing at the sun and in another direction. During a SETI search, when 80-odd foot dish was pointed at the sun, the preamp was completely saturated sat about 1421 MHz. -John ================= > Hi > > If you are on the surface of the earth, you face the sun from time to > time.
