Thanks Dan. I just wasn't sure if the equipment used for 2 meter voice was also out of commission since VHF packet is down...and you have answered my question!

145.800 is being used for most/all USA direct or USA ARISS telebridge contacts. Very strong voice signal as it is using a powerful radio.
E.g.: John Glenn Middle School, Maplewood MN, direct via KØJDD The ISS callsign is presently scheduled to be NA1SS The scheduled astronaut is Shane Kimbrough KE5HOD Contact is a go for: Wed 2017-02-22 18:47:59 UTC 25 deg (***)
145.800 is the default unless a UHF frequency is specified

the specialized communication section (e.g. satellites, EME, APRS, fox-hunting) among other topics.
I'd like to give those students who are already interested sat comms
enough
info so that they can start listening to ISS and the FM sats NOW; the specialized comms topic doesn't come up until a little more than midway through the course.
As a teaser, I plan to give them the downlink frequencies from ISS and FM sats, explain tuning for doppler a little, and show them how to use the Pass Predictions page on AMSAT.ORG.
I know that ISS packet is currently only on UHF (not VHF), but is the 2 meter voice frequency of 145.800 being used, either for random contacts
by
the astronauts, or for school contacts?
None of them currently have packet/APRS gear, so I'm focusing only on voice contacts at least until the class ends (but I'll mention both of those when I do my more lengthy presentation in about a month).
So, in short, my question is - is 2 meters being used at all right now
for
voice from ISS? If not, are random contacts being made on a UHF
frequency?
(I don't see a UHF voice downlink frequency listed in the 2016 "Getting Started with Amateur Satellites" book.)
Thanks
