ZMSDR is a HF software defined radio receiver and transmitter project based on USB controled PIC18F and Si570.

a small collection of tools that I have written to make APRS and SAR operation in local area easier. It was built as a tool to make files for xastir, later a uiview option was added to make the files usable for uiview users. (I downt use uiview only made the files calculation for it)

Simple vox (sound activated) recorder, Perfect for FM scanner purposes, im stuck in old school OSS sound architecture but will be moving over to either PulseAudio or plain ALSA in the future, and build a simple GUI. Help wanted

A library and utilities that allow you to use the ax25/rose/netrom features of the Linux kernel.

ax25-config offers a menu-based configuration of the Linux AX.25 subsystem.

This project is no longer actively developed on SourceForge. Its development has been fully moved to https://github.com/acerion/cwdaemon on 2024.08.03. ------ cwdaemon is a small daemon which uses the PC parallel or serial port and a simple transistor switch to output morse code to a transmitter from a text message sent to it via the udp internet protocol. The program uses the soundcard or PC speaker to generate a sidetone. Current version of cwdaemon is 0.12.0, it has been released in May 2023. Source code for cwdaemon is available on github: https://github.com/acerion/cwdaemon

High performance acoustic softmodem employing multi-carrier modulation (OFDM). Initial code is based on the Dream DRM receiver.

Amateur radio curses based cross-platform logging program written in Python.

ww.eQsl.cc gives a great service for ham radio. With this service you can exchange QSL with other ham radio and when you want, you could access to the web portal and see you eQsl. However a missing point is that you can't download all the eQsl on your local pc at the same time. If you want to download all eQsl, you have to select each eQsl and download it... and waste many time. With this add-on, you can download all your eQSLs in one shot!

a simple c program for an serial elbug = electronic morse key.which is to be plugged to the serial port, its output is also a pin in the serial port. Just compile it by 'gcc elbug.c -o elbug' or use the ready-compiled file and copy elbug to user/local/bin. /* Call it as root. */ How to cable your homebrew elbug? Middle pad: +9V battery via Resistor 2k Left contact: -> DCD (9-pin plug: 1) (25-pin plug: 8) Right contact: -> CTS (9-pin plug: 8) (25-pin plug: 5) Ground: -pole battery (9-pin plug: 5) (25-pin plug: 7) /* by Günther Montag , ex- dl4mge now maintained by Patrick Strasser OE6PSE (trapicki) now actual version also at https://github.com/trapicki/elbug */

This software is provided as a proof of concept and demonstration of maintaining the presence of a number of radio based systems, such as 802.11. This is proof of concept.

The FCC publishes pools of questions for each of the three Amateur Service (Ham Radio) license exams. Two of my programs clean and parse the files and put the questions and answers into a small lightweight database (SQLite) file. The third program generates practice tests which you can focus on particular areas of the exam or randomly select across the pool. The db file in the project is up to date as of February 3rd, 2020. When the FCC issues new/updated exam pools you can use the cleaning and parsing programs to update the database information. The project includes source code files. You may use them in your projects but you must give me attribution according to the GNU License Version 3.

In this project a made a filed strenght meter to check my antenna. The fielduino have a sensitivity control (using a non inverting op-amp)

Various reference programs to read baseband I/Q sample data from a Funcube Dongle Pro+ (FCDPP) software defined radio (SDR) hardware front end, demodulate the data stream and send it to the host's audio output port. Programs are present to demodulate AM, CW, FM and SSB (USB, LSB) streams. Also included is a program that writes FCDPP sample data to its standard output (stdout) port. The programs require the qthid program to control the FCDPP frequency and gain (also available at sourceforge.net. Search for: qthid). Recent activity (10/2014): Added test programs used to construct fun2ssb. See README4; (12/2014) Made program changes to accommodate subsequent complier revisions. For instructions on building qthid-4.1 for Ubuntu 14.04, see a topic under the Discussion menu.

gMFSK is a multimode HF terminal program. gMFSK can send and receive many digital conversational modes typically used by radio amateurs on HF, including MFSK, RTTY, PSK31, and Hellschreiber .

A "simple" demonstration software for decoding ACARS, a low-bandwidth communication protocol used by airplanes to communicate with airports. Detailed description of the operating principles is available at http://jmfriedt.free.fr/lm_sdr.pdf (French) and http://jmfriedt.free.fr/en_sdr.pdf (English). The latest 2022 release for GNU Radio 3.9 and 3,10, following 3.8 named ng for New Generation, aims at adding bitrate clock tracking + removes the external dependence with libfftw by using the GNU Radio FFT wrapper. Doing so, multiple ACARS decoding blocks can run in parallel. Compile for x86 PC with: cd 3.10ng mkdir build cd build cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr .. make -j4 sudo make install (developed and tested on Debian GNU/Linux) Compile for RaspberryPi4/Buildroot (located in BR_PATH): cmake -DCMAKE_INSTALL_PREFIX:PATH=$BR_PATH/output/target/usr -DCMAKE_TOOLCHAIN_FILE=$BR_PATH/output/host/share/buildroot/toolchainfile.cmake ../ make -j4 make install

Block that receives a " message" and send string values over serial connection, to control hardware devices ( switch ), for example, via Arduino based controller ( see https://sourceforge.net/projects/ardu-switch/ ) Prerequisite: pyserial Build as usual for a Gnuradio block: - download and unpack - cd gr-message_to serial - mkdir build && cd build - cmake .. && make - sudo make install && ldconfig If successful this block is into OOT section... Enjoy ;-)

ham radio repeater software controlled controler run your own repeater without expensive hardware just your computer and transcievers made for linux/unix we need help creating this so please email me at kc8yho@kc8yho.org to join in.

hfterm - linux ham radio soundcard digimode program, can monitor and transmit PACTOR I (unique !), also AMTOR, GTOR, RTTY. Based on hfkernel by Tom Sailer, with graphic interface (gtk+), spectrum display, logbook, textmacros, English and German help. Note: I do not maintain it any more so I am happy to announce what Jaroslav Skarvada <jskarvad@redhat.com> wrote to me: "... I patched it [2] to compile and run on current Linux distros and on non x86 machines. I am testing it now, it seems to work (somehow), but it may need more love. I would like to package it into Fedora. Do you accept patches? thanks & regards Jaroslav [1] http://hfterm.sourceforge.net/ [2] https://github.com/yarda/hf/commits/master "
