FWIW they do turn off HamTV for space walks and also
docking/undockings. I think there is one experiment they do
occasionally that they have to turn it off for. But yes, other than
that, it's on all the time.

DTUSat-2 (object 40030) is operating at 2401.835 MHz
sending a full or partial beacon every 30 seconds. Since the Doppler is 100 KHz over the
entire pass, it's tricky copying it with a traditional receiver such as an FT-847
(Doppler correction has to be right on). It's best seen with a SDR. Since its
batteries are dead, it signals cannot be heard in eclipse. Its in an almost perfect polar
orbit and can be copied around noon daily everywhere on earth. It is listed in the AMSAT
keps and pass predictions. Also see http://wakky.asablo.jp/blog/
Also, I've heard that the ISS sends out a very strong video carrier at 2395 MHz (my
converter will not tune that low).
I asked a ham in Italy to check it out and he indicated it is always on.
I hope this helps.
