[RTTY] 2Tone pFSK Keying Circuit

[David G3YYD]

I have added a file to the N1MM Digital file areas. This file documents a
hardware keying circuit that will take 2Tone pseudo FSK output and turn it
into a signal suitable for keying a radio's FSK input. This circuit will
provide an accurate jitter free signal for those who use their radio for FSK
rather than the more flexible AFSK method.
 
The file can be found in this folder:
