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), a JavaScript implementation, a bandwidth-eating UDP implementation, a chat for iOS or a modulated CW over IP using Mumble (iCW).

CWCom Protocol

The CWCom protocol (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.

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).
