[RTTY] Interface Problems

[Edwin Karl]

Yes, That's the issue, using the FSK input (RTTY). I use the packet 
input for AFSK, so
I don't have to mess with the mike etc.

  It's almost as if the tone shifting input is running at high speed, 
not 45 baud.

BTW- the objective is to be able to use the filetrs in the MP in the 
normal, centered
position, not shifting to the outside of the pass band (like on the 
AFSK/ Packet input).
I think this is sofware, and frankly that's where I'm lost.

Thanks for the answer
