Such a system speeds the flow of information during emergency communications. Flmsg įlmsg allows users to send, receive, edit, and create pre-formatted forms.

W1hkj fldigi software#

The software seamlessly integrates with existing email clients such as Microsoft Outlook, Mozilla Thunderbird, and Sylpheed. This protocol is unicast and connection-based. Flarq įlarq implements the ARQ specification developed by Paul Schmidt, K9PS to transfer emails, text files, images, and binary files over radio. This program is useful for multicasting files over lossy connections such as those found on high frequency or during emergency communications. When all parts are correctly received the sent file is re-assembled and can be saved by receiving stations. The program breaks a given file into multiple smaller pieces, checksums each piece, then transmits each piece one or more times. Flamp įlamp implements the Amateur Multicast Protocol by Dave Freese, W1HKJ and is a tool for connectionless transferring of files to multiple users simultaneously without requiring any existing infrastructure. Some of the Suite are however standalone programs used for utility or testing purposes only, with no connection to the Fldigi main modem. Interconnection between these programs and the Fldigi modem is made over TCP/IP port 7322. Most of these extensions add more capabilities to Fldigi such as verified file transfer and message passing. The 'Fldigi Suite' consists of the Fldigi modem and all extension programs released by the same development group.

The Fldigi software is written in highly portable C/ C++ and can be used on many CPU architectures, including: Because of this, the software can run on many different operating systems such as:Īdditionally, Fldigi is designed to compile and run on any POSIX compliant operating system that uses an X11 compatible window system / graphical user interface.

Portability Operating systems įldigi is based on the lightweight portable graphics library FLTK and the C/ C++ language. Transfer of files, emails, and FEMA ICS forms are possible using inexpensive radio hardware. Using this software, it is possible for amateur radio operators to communicate worldwide while using only a few watts of RF power.įldigi software is also used for amateur radio emergency communications when other communication systems fail due to natural disaster or power outage. Increasingly, the software is also being used for data on VHF and UHF frequencies using faster modes such as 8-PSK. Such communications are normally done on the shortwave amateur radio bands in modes such as PSK31, MFSK, RTTY, Olivia, and CW (Morse code). This interconnection creates a 'sound card defined radio' whose available bandwidth is limited by the sound card's sample rate and the external radio's bandwidth. The software is mostly used by amateur radio operators who connect the microphone and headphone connections of an amateur radio SSB or FM transceiver to the computer's headphone and microphone connections, respectively.
