[RTTY] Improving receiving performance

[Jay Bromley]

Hi Rudy,
Here is my Pro III setup:
250hz filter on
Twin Peak Filter
use the RF gain like you decribed below
And/Or use the ATT set around 12 dB.

Last contest I played with MMTTY's decoder.  IIR and PLL seem to work the 
best for me, but the PLL was better over all in the last contest.

I take my audio out of the back DIN plus and into the line level of the 
sound card.  No external DSP boxes used at my location now.  I wonder how 
other Pro III guys are doing with or without external DSP boxes?

Don has a great article on the Pro III on his web site.
