This page needs a lot of love. It is currently mostly raw data that will eventually be used as the basis for some readable prose.


Fedora includes a number of applications and libraries that are of interest to amateur radio operators and electronic hobbyists. This note outlines those applications. Many of these applications are included in the 'Fedora Electronic Lab' spin. Fedora also includes a number of VLSI and IC design tools which have been omitted from this list.

SDR

The Package-x-generic-16.pnggnuradio package is a collection of software designed to implement software defined radio. This is a scheme where fairly minimal hardware is used, and much of the common receiver circuitry is replaced by software.

Packet/APRS

Basic AX.25 packet

The foundation for AX.25 packet implementations is provided by three packages:

  • Package-x-generic-16.pnglibax25 provides the underlying AX.25 capabilities
  • Package-x-generic-16.pngax25-tools provides tools used to configure those capabilities
  • Package-x-generic-16.pngax25-apps Provides a few basic AX.25 applications:
    • axcall: a general purpose AX.25, NET/ROM and ROSE connection program.
    • axlisten: a network monitor of all AX.25 traffic heard by the system.
    • ax25ipd: an RFC1226 compliant daemon which provides encapsulation of AX.25 traffic over IP.

Packet Applications

colrdx DX-cluster client with curses color support

Colrdx is a simple client for amateur radio dx-clusters. In a split-screen display you can type commands for the cluster in the bottom part. Messages from the dx-cluster will appear in the main window. There is also a status line at the top with some basic information.


node Simple node front end, modelled after the node shells of TheNet and G8BPQ nodes

This is a simple node frontend for Linux kernel AX.25, NETROM, ROSE and TCP. It's based on pms.c by Alan Cox (GW4PTS) but has been heavily modified since.


xdx DX cluster TCP/IP client for amateur radio

xdx is a client to connect to a DX-cluster. DX messages will be displayed in a list, announcements will go to a text display.

As well as the usual functions, if you have hamlib installed it can control the radio and set the frequency simply by double clicking a DX-spot (using rigctl).

APRS

aprsd Internet gateway and client access to amateur radio APRS packet data

APRSd is an APRS daemon that uses amateur radio and the Internet to convey weather and positional data in real-time.

PCB includes a rats nest feature, design rule validation, and industry standard RS-274-X (Gerber), NC drill, and centroid data (X-Y data) output for use in the board fabrication and assembly process. PCB offers high end features such as an autorouter and trace optimizer which can tremendously reduce layout time.


Circuit Simulation

gnucap-0.35-4 The Gnu Circuit Analysis Package

The primary component is a general purpose circuit simulator. It performs non-linear DC and transient analyses, Fourier analysis, and AC analysis. Spice compatible models for the MOSFET (level 1-7), BJT, and diode are included in this release. Gnucap is not based on Spice, but some of the models have been derived from the Berkeley models. Unlike Spice, the engine is designed to do true mixed-mode simulation. Most of the code is in place for future support of event driven analog simulation, and true multi-rate simulation.


gspiceui-0.9.65-2 GNU Spice GUI provides a GUI to freely available Spice electronic cicuit simulators such as GnuCAP and Ng-Spice. It uses gNetList to convert schematic files to net list files and gWave to display simulation results. gSchem is used as the schematic generation/viewing tool.


ngspice-17-16 ngspice is a general-purpose circuit simulator program implementing three classes of analysis:

  • Non-linear DC analyses
  • Non-linear Transient analyses
  • Linear AC analyses

ngspice implements the usual circuits elements, such as resistors, capacitors, inductors (single or mutual), transmission lines and a growing number of semiconductor devices including diodes, bipolar transistors, mosfets (both bulk and SOI), mesfets, jfet and HFET.

ngspice integrates Xspice, a mixed-mode simulator built upon spice3c1 and can be modififed to utilize spice3f5. Xspice provides a codemodel interface and an event-driven simulation algorithm. Users can develop their own models for devices using the codemodel interface. ngspice may be used for VLSI simulations as well.


qucs-0.0.14-1 Circuit simulator

Qucs is a circuit simulator with graphical user interface. The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter and harmonic balance analysis.

Logging

LinLog-0.3-4 A amateur radio logbook for Linux

LinLogBook is a highly configurable amateur radio logbook for Linux that uses an SQL database to store its data. For the ease of use SQLite 3 is used but it should be possible to use other databases such as MySQL.


qle-0.0.10 A QSO Logger and log Editor

The qle-package is a graphic QSO log viewer, log editor and QSO logger for amateur radio operators. 'qle' stands for QSO Logger and Editor. It is a Perl/Tk script that logs (or modifies) QSOs directly in a fast and light-weight SQLite database. The term QSO comes from Q code used in commercial and amateur radio communication and in refers to a radio contact. Intended use: casual logging of rag-chew and contest QSOs. The logger caters for CW operators. Table headings, fonts, colours and other attributes are set in a user-editable configuration file. The SQLite log schema supplied may be altered to suit your taste, provided the configuration file is updated accordingly.


xlog-1.7-3 Logging program for amateur radio operators

xlog is a logging program for amateur radio operators. The log is stored into a text file. QSO's are presented in a list. Items in the list can be added, deleted or updated. For each contact, DXCC information is displayed and bearings and distance is calculated, both short and long path. xlog supports trlog, adif, cabrillo, edit, twlog and editest files.

Others

aldo-0.7.5-2 Aldo - Morse code learning tool

Aldo is a Morse code learning tool released under GPL, which provides four type of training methods:

  • Classic exercise - Identify random characters played in Morse code.
  • Koch method - Two Morse code characters will be played at full speed (20wpm) until you’ll be able to identify at least 90 percent of them. After that, one more character will be added, and so on.
  • Read from file - Identify the Morse code generated from a file.
  • Callsign exercise - Identify random callsigns played in Morse code.


dxcc-20080225-4 ARRL DXCC entity identification application

dxcc is a small utility which determines the ARRL DXCC entity of a amateur radio callsign, based on the cty.dat country file by Jim Reisert, AD1C. dxcc has an optional GUI showing the DXCC entity location on a world map.


demorse-0.9-2 Command-line tool for decoding Morse code signals

demorse is a command line tool for translating Morse code signals into text. demorse detects the "dihs" and "dahs" that make a Morse code character via the computer's sound card, which can be connected to a radio receiver tuned to a Morse code transmission or to a tone generator.

The input signal is processed by a Goertzel tone detector which produces "mark" or "space" (signal/no signal) outputs and the resulting stream of Morse code "elements" is decoded into an ASCII character for printing to the screen. Currently demorse is a non- interactive command line tool for the console and decoded Morse signals are sent to stdout.


gpredict-0.9.0-3 Real-time satellite tracking and orbit prediction program

Gpredict is a real-time satellite tracking and orbit prediction program written using the Gtk+ widgets. Gpredict is targeted mainly towards amateur radio operators but others interested in satellite tracking may find it useful as well. Gpredict uses the SGP4/SDP4 algorithms, which are compatible with the NORAD Keplerian elements.


gpsman-6.3.2 A GPS manager

GPS Manager (GPSMan) is a graphical manager of GPS data that makes possible the preparation, inspection and edition of GPS data in a friendly environment. GPSMan supports communication and real-time logging with both Garmin and Lowrance receivers and accepts real- time logging information in NMEA 0183 from any GPS receiver.


gresistor-0.0.1-12 Gnome resistor color code calculator

To allow for identification, resistors are usually marked with colored bands. Often refereed to as color codes, these markings are indicative of their resistance, tolerance and temperature coefficient. gResistor is a great program that will help you translate a resistor color codes into a readable value.


gridloc-0.6-5 gridloc is a ncurses console application for the calculation of Maidenhead QRA Locators from location coordinates, and vice-versa. gridloc also calculates distance and direction from a home location to another location.
