Thanks for the transcription of the audio file.


You are welcome.

I should also add that my computer's clock was about 9 minutes 30 second
behind the official time, so all the time stamps must be advanced by
approx 10 minutes to be correct.


That may be true of the times shown on your web site, but the times
included in my transcription are offsets into the audio files that
have little correlation with time of day, as the receiver's squelch
eliminated all the dead air time.

How have you configured your receiver to record these files? I might
like to do something similar.



It is not difficult to set this up if you have a linux system. It is
an ordinary scanner, and the audio is fed into the soundcard and
captured using the 'sox' software. Sox has switches for selecting the
input threshold (squech) and to do various processing to create
virtually any output format you like. If you are interested I can
send you the script file (really trivial - it is only one line long).

My setup is primarily limited by the fact that the antenna barely
clears the top of my roof but I still get pretty decent reception out
to 30 miles or so.
