It is interesting, too, how the relationships change. Tonight’s pass is about 90 minutes earlier and will be a full six-minute horizon-to-horizon pass (well appears at 10 degrees and disappears at 13 degrees on the opposite side of the sky). But since the rains have set back in I’ll probably not get to see it tonight.

Quote:
Even when the ISS crew isn't operating the ARISS (Amateur Radio on the International Space Station) ham station, one can listen to the station's orbit-to-ground transmissions on other frequencies (as can non-hams, on any of the ISS frequencies, including the ARISS ones). In addition: I just wish they'd try also using some of the low-frequency ham bands such as 40 meters, 80 meters, and 160 meters--the "topside sounder" signal propagation results (from transmitting down [and up from the ground, for the stations on Earth] through the ionosphere) would be interesting. Full-size, half-wavelength 160 meter (1.8 MHz - 2 MHz) dipole antennas and even 1/4 wavelength 160 meter vertical antennas are quite large, but normal-size whip antennas, resonated at 160 meter band frequencies using loading coils and mounted on cars and trucks, are available (and easy to make 'from scratch" as well).
