[GreenKeys] RTTY over VOIP test

[William Wuttke]

Steve,
Copied fine using iPhone speaker piped into a microphone, then to
Voicemeeter Potato, then to Dovetron TU, then to M28. However, (1) No CRs,
only LFs. (2) Tones are 1580/1410 M/S (can only copy on a tunable TU such
as the Dovetron or fldigi, etc.). (3) Looks like there is only a LTRS at
the beginning of the file - it took a while for the figures to turn into
letters.

I'm glad you did this because at least in this test it showed that RTTY
over VOIP does work. Next thing is to try using my VOIP phone (also voip.ms
).

Thanks,
Bill
