[RTTY] Improving receiving performance

[Rudy Bakalov]

This past WPX was my first real attempt to compete on RTTY and based on the experience I have some questions for the experts:
   
  1. For those of you with an Icom 7566P3s, how do you set up your receiver for optimum performance?  I did use the TBF and lowered the RF gain down to about S9+5.
   
  2. How do you configure the MMTTY decoder for maximum performance?  I have a new dual core computer that can do a lot of number crunching.
   
  3. Do you use any external DSP filters between the radio and the computer?
   
  Thanks,
