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.

There are also several free or very cheap Windows apps that do the same
thing. For years, I recorded scanner audio of the local PD / FD.

Will the software you mention not only create the audio files, but FTP
them to a server also?

The software resides on my server, so uploading is not an issue for
me.
If you doing it on windows, it may need extra setup. I will write up
something about the setup and post it to my website in the next few
days.

Probably not, you'd need to script that, or actually save them to the
server.

In my case, I create the mp3 files directly in the public_html
directory on the server, so there is no ftp or scripting involved.
Linux makes this all very easy. I don't know how one would do this on
Windows.

Set the application to save the mp3 file to the public directory? G

I don't think that's all that difficult to do in any operating system.

Can you schedule tasks on Windows like crontab, and set priorities
with nice? May be it is possible, but my linux machine runs unattended
for years without any trouble. My windows machine needs to be rebooted
every few days because it gets slower and slower the longer it stays
on, and something always crashes requiring a reboot.
