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.
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
