[RTTY] using AFSK with TS2000

[Eric Lowell]

You need to apply audio to pin 11 and key the radio with pin 9. Pin 13 
mutes the pin 11 input.

The manual was not written by a native english speaker.

Can you confirm that you have audio on pin 11? (a scope would be good)

Do you have the mode set to SSB?
