This sound experiment is the execution of an idea from user kb7clx:
Take a mono recording from shortwave radio and combine that with a second recording from the same station taken from a different place. - Atmospheric propagation effects will introduce differences in the two signals received at different locations. If these files are combined as the left and right channel, a stereo recording will be obtained.
I looked for what stations I could receive on my small hand-held short-wave radio. Then tunned the online radio receiver from Twente University to the same station.
I recorded the output from my radio upstairs in a quiet room, using my Zoom H1 recorder. I recorded the output from the Twente University website using the built in web borwser recording facility.
Then I merged the two recordings as the different channels of a stereo recording in Audacity.
