Courtesy of a reader and RTO Course alum, one signals intelligence software resource called SORCERER. It’s been around for a minute and the original freeware was plagued with backdoor malware, but courtesy of the website in the link, this version is safe to use. The program is interesting even if it does play havoc on the processor speed of older laptops. Since its a .exe program, if you’re running a linux distro (you are, right?) you’ll need Wine to run it.
Another good one to have on hand is SIGMIRA. Its similar but more laptop friendly and is safe to use. Both are a good resource for use with any RTL-SDR hardware or even Alinco’s DJ-X11T with the supported data cable. Running the whole setup from a used netbook equipped with this software and a Linux OS (all of which can be found in the sidebar of this blog) you’ll be able to demodulate many of the common digital modes in use while maintaining a low profile and keeping the cost down to you and your group.
And if you wanna know how it all works, in a live environment, contact me for one of the open enrollment dates or schedule one for your private group. While we cover basic signals collection in the Advanced Course, we’re planning a possible dedicated SIGINT class coming in the late fall/early winter.

Reblogged this on FOR GOD AND COUNTRY.
Multipsk and FLDIGI come to mind as other popular ones.
Both allow soundcard input with a virtual audio cable (both might now have direct SDR tuning).
FLDIGI runs natively on linux as well as windows and also has a (though slimmed downed) android version (called andflmsg)
FL Digi, obviously, is one of my favorite freeware resources. I brought its value as a signals collection tool (aside from its sending capability) in class last weekend.
These software formats can break much more than commercial traffic, with Sorcerer being an actual sigint tool at one time.
Artemis 2 signal ID software should be a companion for everything mentioned so far.
That’s good stuff 🙂
Question: can you write a post about running digital tools on an Android tablet? I know the square root of jack and shit about digital. Even less about doing it on a tablet for portable work.
I repurposed an old netbook to Linux using the Debian Ham Radio Blend. It still vexes me. I haven’t ventured forward to try Wine windows emulator yet.
So much to learn beyond SSB VOICE and OPSKEDS.
I gotcha. As soon as I get some time to take the pictures, I’ll put up a post. Also, try Mint, Kubuntu or Ubuntu- each of the three have a shorter learning curve with Mint being quite versatile in the signals and intelligence support tasks.
Thanks. I will give mint a try.
