RadioFreeSociety is an unauthorized pirate radio station. We're open to all genres and artists, and hope to put out more stations soon. We'll be here as long as we can get away with it. You'll find a diverse mix of music here, with big names and unknowns. We're aiming for a chaotic energy with very anarchic qualities.
If you're an artist, in a band, or otherwise make cool sounds, feel free to send them on over via email to music@radiofreesociety.com and I'll load them up into the station! I have a lot of big names in the rotation right now, but I'd really like to support the smaller artists and intruduce folks to some new music and up and coming artists and also just regular music for and from regular people.
A disaster-resilient communications network powered by the sun.
When the critical infrastructure that so many of us take for granted goes away, how do we organize ourselves and our communities to respond?
If recent ecological disasters have demonstrated anything, it is the inadequacy of existing models and tools to provide efficient allocation of resources, access to emergency communications, and effective coordination of human effort. Few if any solutions exist that are off-grid, affordable, reliable, easily deployed, and openly standardized.
The Library of Congress and WGBH in Boston have embarked on a project to preserve for posterity the most significant public television and radio programs of the past 60 years: The American Archive of Public Broadcasting. The American people have made a huge investment in public radio and television over many decades, calculated at more than $10 billion. The American Archive will ensure that this rich source for American political, social, and cultural history and creativity will be saved and made available once again to future generations.
In August 2013, the Library and WGBH received a grant from the Corporation for Public Broadcasting to engage in the first phase of a long-term project to preserve public media. During this first phase, scheduled to end in September 2016, the Library and WGBH are overseeing the digitization of approximately 40,000 hours of programs selected by more than 100 public broadcasting stations throughout the nation. Dating from the 1940s to the 21st century and emanating from all regions of the nation, these programs will be available to scholars, researchers, educators, students, and the general public at the Library’s audiovisual research centers and at WGBH.
Generic satellite data processing software. Plug it into an SDR pipeline and it'll try to decode satellite images. Process and interpret in realtime or from recorded traffic. Can use either a local SDR or one shared across a network with rtl_tcp.
In the AUR. There's even a version for Android (in the F-Droid repo).
If the asciidoctor gives you any trouble (specifically, if it keeps saying it can't find itself), it means that it's been installed into the gem directory for a version of Ruby that you're not running (at least for Arch - it was in 3.2.0 but I had 3.0.0 installed).
Two major collections of hobbyist and constructor's books from the UK. There are freely downloadable PDFs of all kinds of radio and electronics related stuff here.
The following is an archive of St. GIGA's broadcasted program "Tide of Sound" (音の潮流) aircheck. The files are given as is from an anonymous source.

Welcome to 101 Things, a collection of projects that celebrate creativity and hands-on ingenuity. If you share a passion for making things, you've come to the right place. Each project uses simple designs, and basic tools, to push the creative boundaries of a home tinkerer. Join me on this exploration of crafting, coding, and constructing, as we unlock the magic of making, one project at a time.
I wrote Trunk Recorder because I was curious about what my local fire station was up to and I put together the original version of OpenMHz because I figured other people might want to listen to the recordings too.
The latest version of this site makes it easy for other people running Trunk Recorder to share their recordings. I am hoping that making it easier to listen to what our local fire, police and EMS have to go through everyday will lead to a greater appreciation for all the work they do, which goes largely unseen.
The audio from each system is archived for 30 days, so you can go back and listen to events you may have missed.

The RFBitBanger is an off-the-grid QRP radio. It is not just designed to be used off the grid, it is designed to be assembled and maintained off-the-grid. Most radios require specialized parts that would be difficult to obtain in an extreme parts shortage or in remote places. This radio is designed to be assembled and maintained using the most common jellybean components that might be in a hobbyist junkpile. It will mainly support low bandwidth/digital modes to make the most of limited power.
This is a single band double-sideband radio, with the band changed by pluggable external filters on 20 m to 80 m. A double-balanced ring mixer is used to provide good rejection of strong stations while not requiring any custom ICs such as SA612 or FST3253. The mixer has strong drive to reduce nonlinearity. The radio is made from readily available through-hole parts which are widely available and have multiple vendor alternatives. The parts needed are very common so that cheap spare parts can be stockpiled or scrounged from other equipment so that the radio may be more easily maintained in off-grid conditions. The includes ATMEGA328P/Arduino Nano, LM358 op-amp, LM386 audio amplifier, 2N7000 MOSFETs, 2N3904 NPN transistor, SS8550 PNP transistor, and a HD44780 display. It can use a SI5351A frequency synthesizer IC soldered to the board, or a plug-in SI5351A development module. There is a MS5351 workalike for this IC as well. Ferrite cores are needed for transformers/chokes which can be easily bought (FT50-43) or scrounged as EMI suppression beads from cables.

RF tool based on CC1101 module and Arduino Pro Micro 8VMHz/3.3V. Allows using CLI to control CC1101 board over USB interface. Putty or any other serial terminal can be used. It has similar functionality to YardStick One but is cheaper and does not need specialized software. Allows for RF jamming and replay attacks as well. It has RAW recording/replaying function which works exactly the same as in the Flipper Zero. Additional function is Radio Chat communicator
You simply connect your Arduino Pro Micro (Arduino Leonardo clone from Sparkfun) to USB port of your PC and launch Putty terminal to communicate with CC1101 module over USB Serial port ( /dev/ttyACM0 port in Linux, COMxx in Windows).
Lofi beats to relax to, mixed in realtime with radio chatter from a randomly selected air traffic control tower.
Mike’s Electronic Parts is located in West Union, Ohio. We specialize in supplying litz wire and electronic hobbyist radio parts and radio kits. Many of the electronic parts will be of interest to Ham radio operators, boy scouts and hobbyists interested in radio. We are also a supplier of litz wire to hobbyist, universities and other businesses. Typically dealing directly with a litz wire manufacturer requires purchasing a large quantity of wire and generally a several week manufacturing process. We stock all wire listed on the site so it is ready to ship when you place your order. We also allow you to purchase in smaller quantities making litz wire available for experimentation and hobbyist.
This site provides summary information about, and access to, the “public inspection file” (or “public file”) for the following types of entities: licensed full-service radio and television broadcast stations, Class A television stations, cable television systems, direct broadcast satellite (“DBS”) providers, and satellite radio (also referred to as “Satellite Digital Audio Radio Services” or “SDARS”) licensees.
The Commission first adopted rules requiring broadcast stations to keep a public file more than 40 years ago and certain political programming files have been public for nearly 75 years. The public file for broadcast stations contains a variety of information about each station’s operations and service to its community of license, including information about political time sold or given away by each station, quarterly lists of the most significant programs each station aired concerning issues of importance to its community, data on ownership of each station and active applications each station has filed with the Commission. The Commission adopted the public inspection file requirement to "make information to which the public already has a right more readily available, so that the public will be encouraged to play a more active part in dialogue with broadcast licensees."
Cable, DBS, and SDARS entities also have public and political file requirements. These entities’ political file requirements are substantially similar to those of television and radio broadcasters. Apart from the political file, however, cable, DBS, and SDARS entities’ other public file requirements differ somewhat from the public file requirements applicable to broadcasters.
Python Django web frontend for playing recorded radio transmisisons. The audio files are recorded using Trunk Recoder.
Trunk Recorder is able to record the calls on trunked and conventional radio systems. It uses 1 or more Software Defined Radios (SDRs) to do this. The SDRs capture large swathes of RF and then use software to process what was received. GNURadio is used to do this processing because it provides lots of convenient RF blocks that can be pieced together to allow for complex RF processing. The libraries from the amazing OP25 project are used for a lot of the P25 functionality. Multiple radio systems can be recorded at the same time.
Trunk Recorder currently supports the following:
- Trunked P25 & SmartNet Systems
- Conventional P25 & analog systems, where each group has a dedicated RF channel
- P25 Phase 1, P25 Phase 2 & Analog voice channels
SDRs supported
- RTL-SDR dongles
- HackRF
- Ettus USRP B200, B210, B205
- BladeRF
- Airspy
