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)).
