[GreenKeys] ITTY to real Teletype

[Harold Hallikainen]

Thanks for the comments! The DSP TU accepts 8 kHz PCM audio, currently
from the on Chip ADC ( https://w6iwi.org/rtty/DspTU2/ ). I have a WiFi
module on the board that I want to connect to ITTY. However, decoding MP3
in the microcontrollers MAY make the DSP functions fall behind, so I'm
looking at having my web server convert the MP3 to 8 bit 8 kHz WAV and
then pass on the PCM audio. The DSP TU would request ITTY from my server
which would then request it from ITTY.

It MAY be possible to do the MP3 decoding in the microcontroller, but I'm
looking at the intermediate server as an option.

THANKS!
