irmc - Internet Relay Morse Code

IRMC stands for Internet Relay Morse Code and is an implementation of MOIP. It implements the CWCom protocol as adopted by MorseKOB.

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.
