Ohio midair crash kills 3

Thanks for the transcription of the audio file. 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.

I live not too far from the accident scene, and I have a scanner that
records all CTAF communications in the vicinity and uploads to my
website. I have not searched the audio archives carefully, but perhaps
one of you might want to take a look and find if anything relevant to
this crash shows up. Here is the link:

Yours may be the sole record of these transmissions. Thank you for
making them available.

From the FAA preliminary information (below):

Here's what I found on the tapes (probably the last words of the MAC
pilots):

06:42 Sky5 You call'n Blue Ash or 229 Sheriff?
06:45 Sheriff Blue Ash
06:46 Sky5 Ok, we're up with ya.
06:48 Sheriff ...they've already called for CFR ...
... about 10 or 15 min out...however
long it takes for them to get goin'
06:57 Sky5 Gotcha. Copy 10 min. We'll stay 2 or
abv 2,000 stay out of your way.
07:11 Sky5 Sky5 helo & Sheriff helo orbiting abt

275blue

So it appears that the Bonanza was inbound from the north at 6,000'
(5,144' AGL) for left downwind entry to runway six, while the Cessna
had just departed runway six and was at 2,100' (1,244' AGL) at the
time of his last transmission. It would seem that both aircraft would
have had their view of the other obscured by their low/high wing
configurations. Tragic.

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.

There is some unintelligible audio at 10:54 that sounds like it might
be the same voice as the Bonanza pilot. Then at 10:57 something that
sounds like "you guys too close".
