Free amateur radio operators software for linux

iRATE radio provides users with a powerful new way to find and download free, legal music online.

Users rate tracks based on their tastes. The iRATE server then selects other tracks to send to the user from a database of over 50,000 freely downloadable songs by correlating the users ratings with other users, and finding people with similar tastes.

Unlike streaming audio, iRATE saves the tracks to the users hard drive. This means that playback is smoother, without the typical problems associated with streaming media, such as high bandwidth usage.

KDE Radio Station presents you a list of internet streaming radio stations. Just select your favorite one, and the media player of your choice will pick up the right stream.

More than 40 radio stations (and more than 90 streams) are already available; thanks to the decentralized structure, many more sources like Icecast directories can be added via metaservers.

And you are now able to share your favorites with other users...

GENRIP is a kernel driver (presently for Linux only) that enables you to carry ethernet frames over generic low-speed/low-power serial radios, such as Microhards MHX series radios. It is intended to speed up the development cycle for those creating low-powered Embedded telemetry and SCADA devices, but may have other applications as well. Once installed, the serial radio simply appears as a network interface like this:

[root@lindev]# ./ifconfig gr0
gr0 Link encap:Generic Radio IP HWaddr 00:00:02:04:06:08
inet addr:192.168.15.1 Mask:255.255.255.0
UP RUNNING MTU:234 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:30
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)

GENRIP was originally based upon Stuart Cheshires STRIP driver, which is part of the Mobile Computing Group at Stanford Universitys Mosquitonet project. It has been radically modified since.

GENRIP was ported to this application by Lawrence Wimble of Design On Demand, Inc. Design On Demand, Inc. maintains GENRIP and hopes that youll call them if you need help with an embedded project using GENRIP (or any embedded project for that matter).

GENRIP is released for Linux under the GPL. A port to FreeBSD is planned in the near future.

GNU Radio is a collection of software that when combined with minimal hardware, allows the construction of radios where the actual waveforms transmitted and received are defined by software. What this means is that it turns the digital modulation schemes used in todays high performance wireless devices into software problems.
What is a Software Defined Radio?
Joe Mitola says, "A software radio is a radio whose channel modulation waveforms are defined in software. That is, waveforms are generated as sampled digital signals, converted from digital to analog via a wideband DAC and then possibly upconverted from IF to RF. The receiver, similarly, employs a wideband Analog to Digital Converter (ADC) that captures all of the channels of the software radio node. The receiver then extracts, downconverts and demodulates the channel waveform using software on a general purpose processor."
For our purposes, on the receive side, the idea is to get a wide band ADC as close to the antenna as is convenient, get the samples into something we can program, and then grind on them in software.
Enhancements:
- GNU Radio 2.6 includes sending and receiving data at up to 1Mbit/sec using GMSK. - Theres also support for the new USRP Flex 400 transceiver daughterboards.
- Handling of all daughterboards has been unified, so most apps will work without modification on any of them. For those of you interested in wireless networking, see especially gnuradio-examples/python/gmsk2. Weve got a framework in place to allow you to build and experiment with your own MACs. 2.6 includes the "null MAC". A carrier sense MAC is the next logical step.

Ragel State Machine Compiler compiles finite state machines from regular languages into executable C/C++/Objective-C code. Ragel state machines can not only recognize byte sequences as regular expression machines do, but can also execute code at arbitrary points in the recognition of a regular language.
Ragel can also be thought of as a finite state transducer compiler where output symbols represent blocks of code that get executed instead of written to the output stream.
When you wish to write down a regular language you start with some simple regular language and build a bigger one using the regular language operators union, concatenation, kleene star, intersection and subtraction.
This is precisely the way you describe to Ragel how to compile your finite state machines. Ragel also understands operators that embed actions into machines and operators that control any non-determinism in machines.
Ragel FSMs are closed under all of Ragels regular language, action specification and priority assignment operators. This property allows arbitrary regular languages to be described. Complexity is limited only by available processing resources.
For example, you can make one machine that picks out specially formatted comments in C code, another machine that builds a list all function declarations and a third that identifies string constants then "or" them all together to make a single machine that performs all of these tasks concurrently and independently on one pass of the input.
Main features:
- Describe arbitrary state machines using regular language operators and/or state tables.
- NFA to DFA conversion.
- Hopcrofts state minimization.
- Embed any number of actions into machines at arbitrary places.
- Control non-determinism using priorities on transitions.
- Visualize output with Graphviz.
- Use byte, double byte or word sized alphabets.
- Generate C/C++/Objective-C code with no dependencies.
- Choose from table or control flow driven output.
Enhancements:
- The documentation and the Ruby code generator were improved.
