Revision as of 02:25, 1 November 2008

Fedora 10 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.

Sound Card Modes

fldigi-3.01-1 Digital modem program for Linux

fldigi is a modem program which supports most of the digital modes used by amateur radio operators today. You can also use the program for calibrating your sound card to WWV or doing a frequency measurement test. The program also comes with a CW decoder. fldigi is written with the help of the Fast Light Toolkit X GUI.

gpsk31-0.3-3 PSK31 for Linux with a GTK+ Interface

gmfsk-0.7-0.5 A Gnome multimode HF terminal for amateur radio

gmfsk is a terminal program for amateur radio digital communication modes for GNOME. It supports MFSK, RTTY, THROB, PSK31, MT63 and Hellschreiber modulations. It is used for keyboard-to-keyboard chatting and not reliable packet communication.

lpsk31-1.1-1 A ncurses application for amateur radio communications using PSK31 digital mode

lpsk31 is a ncurses console application for amateur radio communications in the popular PSK31 digital mode. lpsk31 uses only integer arithmetic for both signal detection and audio tone synthesis, so that it needs no floating point calculations for its operation. lpsk31 can keep a log of QSO's in text and ADIF format as well as a raw log of all that is typed in the transmit window or displayed in the receive window.

xfhell-1.4-4 GTK based amateur radio application for the Hellschreiber communications mode

xfhell is a GTK+ application for the "fuzzy" digital amateur radio communication mode known as Hellschreiber.

xpsk31-1.2-1 GTK+ graphical version of lpsk31 for amateur radio

xpsk31 is a GTK+ graphical version of lpsk31, using the same integer-based signal decoding and encoding engine but controlled by the user via the GUI. In addition it has a FFT-derived "waterfall" display of the incoming signal and a "magniphase" display that shows the magnitude, phase and frequency error of the psk31 signal.


gnuradio-3.1.2-2 Software Defined Radio Framework

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 today's high performance wireless devices into software problems.


aprsd-2.2.5-15 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 offers high end features such as an autorouter and trace optimizer which can tremendously reduce layout time.


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.

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.


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 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 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.

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.
