One radio is in the Colombus module and used by European, Japanese, US etc.

The other radio is in the Russian segment.

At the moment the Russian segment is being used for school contacts as
there is no astronaut in the European section with a licence.

So two radios, two different locations. There was a high power radio
in the Colombus module but it is not working. The handheld is a
backup, currently in use.

The two sections are as such independent, with co-operation. There are
different voltages in different sections which also makes moving
equipment from one to another very difficult. The section used depends
on the Nationality of the astronaut. SSTV always seems to be Russian,
probably due to equipment in that module. Packet is always European,
as far as I know.
