[GreenKeys] Loop over IP

[Harold Hallikainen]

I think there is a method of doing Morse over the Internet for remote
operation of transceivers, but I don't know how it is done. To do on/off
keying instead of, possibly, baudot to ASCII conversion and then
transmission over TCP, I'd probably transmit the time of each transition
to mark and the time of each transition to space. This again could be sent
over TCP or UDP.

As far as audio, my DSP TU (https://w6iwi.org/rtty/DspTU/ ) uses 12 bits
per sample at 8 kHz sample rate. The 12 bits per sample is because that's
the size of the ADC on the chip. All calculations are then done as double
precision floats. In general, I think 8 bit at 8 kHz would handle RTTY
fine.
