The Russian suits, whether with US or Russian people
inside, use 130.165 FM. So always check the NASA
releases and read them carefully. This is VHF-2 (VHF-1
is 143.625 which Gagarin used when he was a boy). Its
used in EVA on orbits which start over Eastern Siberia
and head West (so that there is maximum exposure to
Russian groundstations); a 6 hour EVA means we can
hear the closing stages at low elevations here in the
UK. (Obviously you can check this with up to date keps
and announced EVA times). We heard it a week or so
ago on the first EVA, but on the second they were
tucked up safely by the time they were over us.
Personally I think the suits relay to an onboard
repeater (but what do I know).
You Yanks now use some other spread spectrum or
similar system that we can't hear (yet ;>)). the old
frequencies are dead (as is VHF-1).
The shuttle uses (allegedly) 259.7 AM over the UK as
she boosts into orbit but I didn't hear her last time
despite sitting in the garden at 1 am local time (not
very cold and not raining, just feeling silly).
