Jeff,
I was in the same situation with native RTTY and PSK decoding with the K3.
We camp a lot in our small RV trailer and I wanted to master the native
capability B4 hooking up a computer. I just couldn't get the hang of tuning
PSK and RTTY, but got it down pat now. Most of the ham band RTTY QSOs were
too short to get the hang of tuning, and I mastered the PSK tuning first.
Here are my suggestions ~
-- change the RTTY pitch decode to 915 instead of 2125. I found it easier
to listen with my ear, having set CW pitch to its highest of about 900 hZ.
I was trying to find the 'audio tone sweet spot', so to speak.
-- find some strong RTTY transmissions. The two that helped me the most
were the W1AW 3PM and 6PM Pacific data transmissions on Mon thru Fri. If
those times are inconvenient, then on Saturdays the 'old' coastal station of
KPH has been re-licensed as KSM under the wonderful sponsorship of a group
of folks. http://radiomarine.org/ And they do RTTY transmissions long enuf
to zero in. I'm not taking anything away from what the other folks have
said as they have been most helpful to me. So I would start tuning up in
FSK D mode until the leftmost bars when solid and could hear the 915 pitch
tone. Once you got it decoding on those transmitters, then you can play
with narrowing the filter BW and trying the DUAL PB.
Good luck...
Dennis
