[amsat-bb] A/C to ISS Contact

[Graham Shirville]

Not quite the same but I remember listening to the ATC at Luton Airport 
trying to respond to a call from MIR - both use(d) 121.75MHz. Presumably 
the Doppler on the FM signal from MIR was sufficient for the AM receiver 
at Luton to slope detect the audio. I cannot remember if the cosmonaut 
actually replied...
