So I listened for the moonbounce echoes on 6792.5 kHz this weekend.
With a Kenwood R-2000 and a random wire, with a significant (s3-s5) local noise level, I was able (barely) to hear the reflected signals. There was much fading. I note this in others reports as well. I understand the mechanism (I think...) for fading with normal sky-wave. How is the QSB explained on a direct signal from/to the moon? Does the effective path length through the upper atmosphere actually vary by as much as 1/2 wavelength? When moving directly up through the atmosphere? What's the story? Regards PN2222A NPN (Is = 14.34f Xti = 3 Eg = 1.11 Vaf = 74.03 Bf = 255.9 Ne = 1.307 Ise = 14.34 Ikf = .2847 Xtb = 1.5 Br = 6.092 Isc = 0 Ikr = 0 Rc = 1 Cjc = 7.306p Mjc = .3416 Vjc = .75 Fc = .5 Cje = 22.01p Mje = .377 Vje = .75 Tr = 46.91n Tf = 411.1p Itf = .6 Vtf = 1.7 Xtf = 3 Rb = 10) |
