[GreenKeys] TDD Frequencies

[John Spigel]

Gavin. Alternately, I've posted both a 45 baud and a 75 baud mp3 file here:

https://5bits.net/1400-1800/teletype-RTTY-45.mp3
and
https://5bits.net/1400-1800/teletype-RTTY-75.mp3

Just makes things easier to play off a smartphone. Hope I got the M-S 
correct. Long term you may want to find a terminal unit or put together 
one of the deramp boards to drive your 28.

Enjoy!
