Jean Marc,
FM voice contacts on the 2 Meter frequency pairs is a rare occurrence.
There have only been a couople of pre-announced session the past five years.
SO … Please watch AMSAT and ARISS for announcements!
And keep on monitoring! Remember the ISS astronauts usually work on UTC time … and
you can look up the daily schedules at the involved agencies’ Web sites to see when an
astronaut might be working in the ISS module with the ham equipment.
But it is very rare to work them lately - when not a pre-publicized event!
