What is IRMC?

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)

Serial Drivers

TBD: Driver: serial - 2usb!

How to use:

The usage is: irmc [hostname] [port] [channel] [id] [serialport

For example: `./irmc mtc-kob.dyndns.org 7890 103 MyID /dev/tty.usbserial´

I have been using cwcom to practice sending morsecode, unfortunately my main computer at home is running openbsd and it has gotten harder to gain access to a reliable MS Windows machine. So I wrote my own client that works on openbsd. This is written in C and although not tested it should compile under other OS. If any one wants to try it and send me feedback. you can download version 0.01 here http://fernan.bitbucket.org/irmc.tgz Les Kerr of https://home.comcast.net/~morsekob/ has been very patient in answering my questions regarding the cwcom protocol and setting up a test server during debugging.

There are few difference between this and the official cwcom client

1. It is a command line tool
2. It does not send the characters of the message to the receivers screen.
3. It does not translate CW for you. You can try fldigi if you just want see the transmission.
4. Tone pitch is currently hard coded to 650Hz
5. It does not have a way to show you who is listening.

Bugs: There are a few that I am working on right now, but feel free to send me feedback if you get a chance to try it out.
