irmc - Internet Relay Morse Code
|
|
================================
|
|
IRMC stands for Internet Relay Morse Code and is an implementation of [MOIP](http://8ch9azbsfifz.github.io/moip/).
|
|
|
|
# Building
|
|
## On Linux
|
|
Install portaudio, i.e.: sudo apt-get install libportaudio-dev
|
|
|
|
# Hardware interface options
|
|
A good description on how to build different 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).
