Hello Howard,

It is verry simple to find out what mode ISS ham radio is active.
First you can look at the status reports from other people in
the world.
The reports are shown on the ISSFANCLUB main page (right side at the top).
Or check out by yourself when the ISS comes in your range.

145.825Mhz packet (mostly active, but at EVA periods off).

CREW IN VOICE WITH MOSCOW FLIGHT CONTROL (NOT A HAM RADIO FREQ!!!).

the "ISS footprint" is in range of moscow and you!
