...This is easy to determine; refer to the manual at https://mfjenterprises.com/products/mfj-993b#product-manuals *Note for ESP32* See https://github.com/dl9sec/MFJ-993WWRC for working with ESP32 modules. It works very well with the MFJ-993B and is a great project! Opto-Isolators are recommended rather than FETs ! Enhancements to this may appear that include additional functionality that this project incorporates.

This project is no longer actively developed on SourceForge. Its development has been fully moved to https://github.com/acerion/cwdaemon on 2024.08.03. ------ cwdaemon is a small daemon which uses the PC parallel or serial port and a simple transistor switch to output morse code to a transmitter from a text message sent to it via the udp internet protocol. The program uses the soundcard or PC speaker to generate a sidetone. Current version of cwdaemon is 0.12.0, it has been released...

Moved to github: see https://kb1vc.github.io/SoDaRadio/ SoDaRadio is an allmode VHF/UHF SDR transceiver built for the Ettus Research USRP N2xx and B2xx software defined radio platforms. It is designed for use by amateur radio operators. It has been used as a general purpose receiver, and as an exciter/IF for microwave transverters.

hfterm - linux ham radio soundcard digimode program, can monitor and transmit PACTOR I (unique !), also AMTOR, GTOR, RTTY. Based on hfkernel by Tom Sailer, with graphic interface (gtk+), spectrum display, logbook, textmacros, English and German help. Note: I do not maintain it any more so I am happy to announce what Jaroslav Skarvada <jskarvad@redhat.com> wrote to me: "... I patched it [2] to compile and run on current Linux distros and on non x86 machines. I am testing it now, it...

An asynchronous Text to Morse Converter and Morse training software for Arduino Uno, based on interrupts and Timer1. And because it doesn't use that evil delay() function, this solution morselizes random letters or whatever it receives through its serial() interface, in a non blocking manner. https://github.com/vicival/morselizer

The SARK100 SWR Analyzer (https://sites.google.com/view/sark100) is a measurement instrument which determines antenna system performance across the HF/6M amateur bands through use of automatically collected SWR and complex impedance readings.

a simple c program for an serial elbug = electronic morse key.which is to be plugged to the serial port, its output is also a pin in the serial port. Just compile it by 'gcc elbug.c -o elbug' or use the ready-compiled file and copy elbug to user/local/bin. /* Call it as root. */ How to cable your homebrew elbug? Middle pad: +9V battery via Resistor 2k Left contact: -> DCD (9-pin plug: 1) (25-pin plug: 8) Right contact: -> CTS (9-pin plug: 8) (25-pin plug: 5) Ground: -pole battery (9-pin plug: 5) (25-pin plug: 7) /* by Günther Montag , ex- dl4mge now maintained by Patrick Strasser OE6PSE (trapicki) now actual version also at https://github.com/trapicki/elbug */
