irmc - Internet Relay Morse Code

IRMC stands for Internet Relay Morse Code and is an implementation of MOIP.

How to build?

Install dependency: morse keyer library

wget https://github.com/8cH9azbsFifZ/morse/archive/v0.1.tar.gz
tar xzf v0.1.tar.gz
cd morse-0.1
libtoolize
./autogen.sh
./configure  --with-portaudio
make
sudo make install

Debian (Wheezy)

Some dependencies have to be installed:

apt-get install -y alsa-oss oss-compat build-essential autoconf libao-dev libtool

Afterwards compilation with make should work. If something went wrong, you may have to adjust your LD_LIBRARY_PATH. Alternatively try:

LD_LIBRARY_PATH=/usr/local/lib ./irmc mtc-kob.dyndns.org 7890 33 123 

OSX (Yosemite)

Compilation with make :)

For the USB serial devices you need a PL2303 driver (i.e. PL2303_Serial-USB_on_OSX_Lion.pkg).

Hardware interface options

A good description on how to build different interfaces (telegraph key, sounder or both) is given on the MorseKOB Website. Landline telegraphs use "closed circuits" for communications; if you have built one at home, you may also use the loop interface.

Connection of a morse key: layout of pins

RS232 DB9 Function
DTR 4 Manual Key / paddle common
DSR 6 Manual key / dot paddle
CTS 8 Dash paddle
RTS 7 Sounder output
SG 5 Sounder ground

Changelog

  • v0.3 zip - commandline option cleanup
  • v0.2 zip - ported to debian wheezy and osx yosemite, DG6FL
  • v0.1 zip - original version, VE7FEB

Code Quality

This is experimental code.
