The Radio Amateurs from the Sternwarte Bochum (observatory of Bochum Germany) will launch a weather balloon with a 2m transmitter. 
On 145.200 MHz in FM it would transmit the callsign DA0SPUTNIK and the historic signals from Sputnik. 
The power is 1 Watt into a whip (or similar) antenna.
If the balloon rises to an altitude of 25 km it could be heard in the whole of Central Europe.
