Looking at JE9PEL's SatsList at http://www.ne.jp/asahi/hamradio/je9pel/satslist.htm I see there are seven satellites listed as active with at least one of their beacons near 2.4 GHz:

14781 UO-11 2401.5 (steady carrier)

43804 Suomi-100 2410.0

43786 ITASAT-1 2400.15

43743 Reaktor Hello World 2410.0

43669 Tiayni-4 2409.0

43155 Tiayni-2 2403.0

42775 AALTO-1 2402.0

Are any of these routinely active over the western US? And, any sat beacons in the 10 GHz band?
