Open Source ChromeOS Ham Radio Software

The WSJT project implements software for amateur radio communication using state-of-the-art digital techniques. Typical applications involve "DXing" at LF, MF, HF, and VHF+ frequencies, including meteor scatter and EME ("moonbounce"). Major emphasis is placed on weak-signal techniques. Summary Program Descriptions: WSJT-X supports the communication protocols FST4, FT4, FT8, JT4, JT9, JT65, Q65, MSK144, WSPR, FST4W, and Echo, each optimized for different sorts of radio-wave propagation. MAP65 is designed for EME an VHF and higher frequencies. It provides a panoramic, polarization-matching receiver for the Q65 and JT65. modes. Programs WSJT and WSPR are interesting primarily for historical reasons. They are superseded by WSJT-X.

A cross platform Python frequency scanning GUI for USB TV dongles, using the OsmoSDR rtl-sdr library. In other words a cheap, simple Spectrum Analyser.

Open source libraries and utilities to support using digital signatures for Amateur radio QSL information.

A software gps simulator, providing TCP/IP, UDP, http and serial port connectivity in NMEA 0183, XML or user defined output format. Usable for testing all kinds of GPS applications. Can playback pre-recorded GPS files with NMEA output.

CWStudio is a portable almost library-independent and computationally efficient generator of CW signals for telegraphy training purposes. It can create a sound with maximum similarity to the real air, simulating many difficulties.

QAntenna is able to show antennas in a 3D plot, and calculate it's radiattion pattern. It is capable of working with many antennas at the same time.

Morse Code (CW) decoder for Unix-like systems (and Windows).

Ham's Actor is a software for radio hams. Is a bundle of many functions and tools, so you just have to have one software. Functions: Log Book, GrayLine, satellite tracing, contesting, maps, callbook, and so on...

A program for use by radio hobbyists to decode the data sent to mobile display terminals used by taxi companies.

A program to allow the easy triagulation of a transmitter during a trasmitter hunt

finds exact gain, directivity and input impedance of Yagi or log-periodic antennas (planar symmetric array of cylindrical dipoles, many driven elements) for a range of specified frequencies, integrates 2D for segments on the same element, moment method

Ham Radio Exam is a program to help prepare for one of the FCC amateur radio exams (technician, general, or extra). The program allows you to take practice exams or all the questions in a section. You can save a list of questions to test on later.

PyMorseRSS is a project using Python to generate Morse code practice files and making them available via RSS. The Morse code practice files are generated according to the Koch method using Farnsworth timing and both MP3 and OGG outputs are supported.

JMorseTrainer helps you to learn or improve Morse code.

This project is to create the hardware and software for a family of software defined radios for microwaves and maybe other bands too. The DSP in the software is based on DttSP from the SDR-1000.

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)

This is ham java software used by italian radioamateur by which they are able to manage their qso and print their qsl

A portable library to control the ICOM PCR-1000 computer controlled general purpose radio receiver and gui front ends for X, Aqua, and windows32

Collection of HAM radio APRS tools: - METAR to APRS WX data injector

Tracks runner's in/out time at each aid station. Saves data in CSV file. Can be configured for other races. AidStations.txt in repository contains the 15 or so Aid Stations used for the Bear100. The Bear100 is an annual 100 mile, 2 day race on foot through the Rocky Mountains in North America. Will communicate via serial over a 1200 baud AX.25 link to a ARES/Data backend (which we call NetControl). Can initialize some hardware TNCs with parameters optimal for ARES/Data topology. See ARES paper for topology/backend: http://www.tapr.org/pub_cnc07.html All Aid Stations are expected to use same frequency concurrently, and optionally send queries to Net Control. Note backend will support more frequencies if more radios were hooked up. Expected that subset of stations will use software. Remainder will communicate runner data via voice to NetControl.

Test your knowledge of ARRL and RAC Sections and US States and Canadian provinces. Helps improve your logging rate for all Ham Radio contests that require logging sections, or states, and provinces, including Field Day, Sweepstakes, ARRL DX, etc

Next generation APRS iGate for HAM radio use.

The DXSpider DX Cluster is a linux based, (mainly) perl program designed to provide the same general functionality (and more) as the DOS version originally written by Dick Newell AK1A.

A CW beacon implemented in C language on a AVR AtTiny13A microcontroller (1KB flash!). Include a CW parametric modulator/keyer, an emulated I2C periferal and a device driver in order to handle the Si570 oscillator by Silabs. You can personalize the transmitted message and the morse speed (in WPM). In the example the beacon is IQ6MC/B JN63RH @ 144.450MHz. Enjoy this example and if you will appreciate it, please sens me a feedback! IW6DFW, Maurizio

FreqLength is a simple wavelength calculator that takes a given frequency as input and spits out various wavelength values for that frequency (full wave, half wave, etc.) If you'd like to donate there's several ways to do so: PayPal: https://paypal.me/gerowen Bitcoin (BTC): bc1q86c5j7wvf6cw78tf8x3szxy5gnxg4gj8mw4sy2 Monero (XMR): 42ho3m9tJsobZwQDsFTk92ENdWAYk2zL8Qp42m7pKmfWE7jzei7Fwrs87MMXUTCVifjZZiStt3E7c5tmYa9qNxAf3MbY7rD LiberaPay: https://liberapay.com/gerowen
