[Elecraft] KIO3B RTTY AFSK problem with Transmit

[Bill Frantz]

Use AFSK A mode for RTTY. DATR A can also be made to work, but 
my experience with AFSK A is much better. FSK D does not use the 
sound card for transmission.

Make sure your computer is producing enough output drive. On my 
Mac I need to go to System Preferences -> Sound and raise the 
output volume all the way.

Make sure your application is addressing the correct USB device. 
(Don't ask how I know.)

Input from the radio should work but might be low in volume. 
Some of us set Config: LIN OUT to about 40.
