Using Mumble( open source skype like voip program )and FLdigi to communicate morse code over the internet.  LIVE RECORDING from 2009. [ Missouri to Michigan internet path ] 

SETUP:  using a virtual audio cable, we connect the output of FLDIGI to the input of MUMBLE.  We both connect to a MUMBLE SERVER and instead of using MICROPHONES, we send morse code audio tones at high quality, high fidelity, and low latency, to each other.  The audio is FULL DUPLEX and allows for good QSK response during the conversation for breaking in.
