Fldigi is a modem program for most of the digital modes used by radio amateurs today: CW, PSK, MFSK, RTTY, Hell, DominoEX, Olivia, and Throb are all supported. It can help calibrate a sound card to a time signal and do frequency measurement tests. NOTICE: You must proceed to the Files section to locate the correct fldigi, flrig etal download for your particular operating system. Do not blithely use the big green Download button! Use the "Files" menu item or the "Browse All Files" link.

Flmodem is a sound card based modem that is used for higher-speed digital modes over an amateur radios 9600-port. It is a patch-set (small modification) applied on top of the normal Fldigi releases. The code modifications increase the usable audio bandwidth from 4000Hz up to 8000Hz. Program works as a pure-modem requiring external propgrams to operate (no tx/rx chat window) Can run simultaneously alongside Fldigi on the same computer. Currently there is only 1 modem which uses...

Hamradio HF digital teletype modem for PocketPC.

TIVAR can receive and decode multi-language text and images using analog AM, FM, or Shortwave receivers. The audio from a radio receiver is coupled to an Android device either through the built-in microphone or by a physical connection (audio patch cord). The software then decodes the modem-tones into readable text and save-able images. These new digital transmissions are currently sent by a few shortwave-frequency stations: W1AW VOA Radiogram Mighty KBC These digital broadcasts...

Ham ARM Linux - Digital operations mainly focused on AX.25 using packet modems. This project is about making the ARM single board computers come to life for Ham Radio in a controlled and structured way, so operators can learn the ins and outs of packet radio. There will be an image for each supported board, and a set of shell scripts to help the user to configure their system simply and properly. HAL hopes to cut out the days of circular searching on the internet for how to get a simple...

DSAquire allows you to download and plot trace data from a Thurlby DSA524 digital storage adaptor (it's a 25 year old instrument, but better late than never, eh?). The data is downloaded via an RS232 serial link using a null modem cable. You can export the plot as an image or export the data in real-world units as a csv file. This software runs under Linux and also under Windows XP and later using Cygwin. Pre-compiled binaries are supplied, as are full sources under the GPL. The interface...

This project is Ubuntu with fldigi digital modem, flrig, flarq, flmsg, flwrap, and Xlog pre-installed. The CompizConfig Settings Manager is included so vision-impaired amateur radio operators can use Enhanced Zoom magnification. The LiveUSB will run on most PCs with a 32-bit or 64-bit CPU. The support page is http://www.hamradioandvision.com/fldigivi-liveusb. Topics include: 1. Using UNetbootin to make a LiveUSB. 2. Enabling magnification. 3. High visibility text.

Arducc is an avr-based platform that is optimized for automotive and industrial systems. It supports the CAN bus protocol, includes a GSM modem for tracking purposes, a set of relays for general purpose, a low quiescent current voltage regulator for low current drain of MCU when battery powered, and a switched mode power supply (SMPS) for modem. MCU is an ATMega328P device with several capabilities such as low power AVR 8-Bit micro-controller, three timers, six pulse with modulation (PWM...

Firmware for AVR32 based DV-Modem (addon for Siemens C5) / DV-ATRX. Its used with analog (fm) ham tranceivers to transmit digital voice (D-Star and more) or data.

This firmware is used for the AVR32 hardware called 'DV-RPTR' (= "repeater"). This little piece of hardware works as a duplex GMSK/GFSK modem (first goal) to transport digital voice data through USB CDC to/from a PC.

To provide a handy tool for user to develop Zigbee application base on Digi/Maxstream Zigbee Module. The source code is Visual Basic 6/ VB.net base.

A Software Modem that converts user typed text into a binary stream which is sorted and transmitted as two seperate synthesised sounds which match up to a zero or a one to allow the receiver to distinguish between a digital mark and space.

Montage is a web photoalbum that can be run on any platform supporting J2SE 1.4 / TomCat 4. It utilises a large number of Apache Jakarta projects and is designed to perform well over modem links (transfer compression, progressive JPEG, CSS2, page expiry
