As Mike already mentioned very strong signals. There where two signal patterns. The first was switching between 435.265.000 and 435.365.000 MHz and after halfway the pass there was a second pattern only on 435.365.000. Visit http://www.pe0sat.vgnet.nl/2012/i-received-date-from-rs-40/ so you can listen to the two different signals.
I used Object D as mentioned on http://www.zarya.info/ MiR (Yubileiny-2) 2012-041D 38736 in orbit.
Thanks Jan. You’re right. The first audio pattern is telemetry. The second audio contains only data e.g. a memory dump.
This is a sample of a telemetry channel from the first audio file.
You can see different channels (solar panels etc., voltages, currents). There is also an timestamp. A transmission block covers 30 minutes.
