# Hardware interface options
2015-07-07 17:53:40 +00:00
A good description on how to build different interfaces (telegraph key, sounder or both)
2015-02-15 12:13:22 +00:00
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).
