Stereo_Shortwave_dig_2014-07-15T15_17_10187.0-10191.0kHz_AM.mp3

Shortwave wide-band digital emission recorded on July 15, 2014 at 15:17 UTC in AM mode using 2 instances of the online remote controllable short-wave receiver located at the amateur radio club ETGD at the University of Twente The Netherlands. Left channel was recorded below the central frequency, at a frequency of 10187KHZ, right channel was recorded above the central frequency, at 10191KHZ. This was an experiment to see if selective fading would create stereo effects, as the lower frequency part of the transmission would be heard better in the left channel, and the higher frequency component would be heard better on the right. I used Goldwave to put the separate recordings into 2 channels of the same file, after I synched the recordings by ear at 1/16 playback speed using a set of 2 particularly strong lightning static crashes as a guide, trimming off everything that came before the first strike in both original recordings, then inserting silence in the range of a few milliseconds until the stereo separation was as close to zero as I could get it. I wasn't as successful at that as I've been with experiments with voice recordings from simultaneous broadcasts on 2 wavelengths that I haven't posted here.
