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).
