For the scheduled events, yes. Most ISS voice activity will be on the cross-band repeater, including random QSOs by ISS crewmembers. The repeater downlink is 437.800 MHz (+/- 10 kHz for Doppler - around 437.810 MHz at the start of a pass, ending around 437.790 MHz near the end), and the uplink is 145.990 MHz with 67.0 Hz tone.
I saw reports that an ISS crewmember was on the repeater this (Sunday, 12 October) morning before 11am PDT/1800 UTC. Crews have more free time on weekends, so you could hear a crewmember talking to hams some time...
73!
That's the correct frequency to hear amateur radio transmissions from the ISS.
I imagine that NASA, Roscosmos, ESA, etc., have other means of communicating with their assets on regular basis.

Yes CB62. That is the correct frequency.
145.8.
I have monitor is from my car with my Uniden ht. scanner and a mag mount antenna.
Never have talked uplink but heard them.
Really cool.

Many years ago (late 1990's?) there were ham repeaters that would 're-broadcast' ISS comms (might have been Space Lab back then). I don't know where they got the comms from but they would re-broadcast them on Ham repeater freqs. Apparently they don't do that anymore. THOSE were some interesting comms.

NASA public feeds. I don't remeber if it was from the internet or satellite back then. Now they have several internet streams.

I remember the repeater in Ventura Co area in the 1990s.
Not sure what machines did the simulcast.
My dad monitor that like crazy.

As far as I can remember, it was a NASA public feed available on Echolink, and some repeaters equipped with Echolink were manually connected to the Echolink node.
I know because there was one repeater in my area that the older hams fans of space and NASA were connecting when there were important events
(I seem to remember Space Shuttle launches, as “special events” broadcasted this way, but my memory may play me tricks!)
