irmc - Internet Relay Morse Code
|
||||
================================
|
||||
|
||||
# What is IRMC?
|
||||
IRMC stands for Internet Relay Morse Code. It implements the [CWCom protocol](http://kob.sdf.org/morsekob/docs/cwcom.pdf) as adopted by [MorseKOB](http://kob.sdf.org/morsekob/docs/history.pdf). You can try out the software in a [browser](http://kob.sdf.org/morsekob/morsekob30/index.htm) using Java.
|
||||
|
||||
## Why morse code over IP?
|
||||
Why not? A number of different approaches for CW over IP exist. An early implementation has been the CWCom protocol,
|
||||
which has been the basis for Morse KOB, a ready-to-use software. Both chat programs have been written for CW exclusively and are compatible. An alternative implementation in C exists as well as a port to the ATMEL AVR Microcontroller.
|
||||
|
||||
Besides a variety of other approaches exist, for example an IRC plugin ([CWirc](http://myspace.voo.be/pcoupard/cwirc/)), a [JavaScript implementation](http://morsecode.me), a [bandwidth-eating UDP implementation](http://hans.liss.pp.se/node/343), a [chat for iOS](http://pignology.net/cwwithme.html) or a modulated CW over IP using Mumble ([iCW](https://sites.google.com/site/icwoip/)).
|
||||
|
||||
IRMC stands for Internet Relay Morse Code and is an implementation of [MOIP](https://github.com/8cH9azbsFifZ/moip).
|
||||
It implements the [CWCom protocol](http://kob.sdf.org/morsekob/docs/cwcom.pdf)
|
||||
as adopted by [MorseKOB](http://kob.sdf.org/morsekob/docs/history.pdf).

## Hardware interface options

A good description on how to build differnt interfaces (telegraph key, sounder or both) is given on the [MorseKOB Website](http://kob.sdf.org/morsekob/interface.htm). Landline telegraphs use "closed circuits" for communications; if you have built one at home, you may also use the [loop interface](http://kob.sdf.org/morsekob/docs/loopinterface.pdf).
