MoIP - Morse over IP
====================
In analogy to voice over ip (voip) we can also do morse code over ip (moip).
A number of different approaches for CW over IP exist. Here we describe the
well-establised CWCom protocol (since 1998). 
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/)).

# CWCom Protocol
The [CWCom protocol](/doc/cwcom.pdf?raw=true) (cw communicator) is an effective method for transmitting
morse code signals as UDP packets over IP. 
 
## CWCom Servers
The clients will connect to one of the servers using the CWCom protocol.

The source code for a server on a Raspi can be found [here](https://sites.google.com/site/morsekob/server).

## Compatibility 
The original CWCom protocol has been extended for MorseKOB, as landline telegraphy uses 
closed circuits (latching). There are mainly two server types for moip (see below):
the original CWCom server and the MorseKOB server. Both servers are compatible using a
relay server written by Bob Denny ([source code](https://github.com/8cH9azbsFifZ/moip-relay-server/tree/master)).
