Black Cat ALE Vacuum Cleaner

Black Cat ALE Vacuum Cleaner processes SDR I/Q recording files, looking for and decoding ALE signals found in the passband. (It only works with recording files, not with "live" signals.)

This makes it possible to quickly and easily find many of the ALE transmissions in your SDR recordings, without having to manually find and decode them one by one. You don't have to monitor just one ALE frequency, or a few. Or even specify which frequencies to monitor! Black Cat ALE Vacuum Cleaner will look for ALE transmissions on any channel (in 1.0 and 0.5 kHz steps) that fall within the bandwidth of your SDR I/Q recording files.

It can even run in an "unattended" mode, monitoring the directory your SDR program writes recording files to. As each I/Q file is finished, Black Cat ALE Vacuum Cleaner will process the file, logging ALE transmissions to a text file, and then delete the I/Q recording file, so your hard drive doesn't fill up.

It reads SDR recordings from many popular SDR programs:

  • SDR Console
  • SDRuno
  • SDR Sharp
  • Elad
  • SpectraVue
  • SdrDx

    A copy of the documentation is included with the download as a pdf file, however you can also read it online here so that you can see how the program operates, and it's many features.

    Please remember that the program is searching through the entire I/Q recording file looking for ALE transmissions. It may not find all of them. It may also "find" transmissions that don't really exist, either due to noise or other signals being mis-identified. The emphasis of the program is weak signal detection, over rejecting any and all false signals. It's up to you, the user, to weed out the bad from the good.

    Also note that the 0.6 kHz channels used by the US State Department are not officially decoded, although you may occasionally get some decodes from them as a 0.5 kHz channel.

    Purchase a licence code for your copy of Black Cat ALE Vacuum Cleaner:

    Black Cat ALE Vacuum Cleaner is available for download prior to purchase. That means you can, and should, download a copy and fully test it on your system before buying a license code. Use it as much as you want, for as long as you want. Make 100% sure it works correctly on your setup, and meets your needs. Only then buy a license code.

    If you have any questions about using the program, or think there's a bug or issue, send me an email before buying a copy. It's possible there's an actual bug in the program that I need to fix (which is why I love to get bug reports!) or an incompatibility with your setup that will prevent the program from running. Entering in a registration code won't fix them.

    Please take full advantage of this, and don't buy a copy before you've properly evaluated the program. I want you to be 100% satisfied with your purchase.


    $99.99 Registration code sent by email, software download

    Black Cat ALE Vacuum Cleaner is only $99.99 (Introductory pricing). Purchase also entitles you to all updates and new versions released over the next full year, free of charge, which of course you can continue to use forever.
