I don't know which "706" you have, but there's another option for the
706MKIIG.  I use the FL-232 350 Hz filter for RTTY, and I think it's near
optimum.  You can do RTTY with 250 Hz, but it gets problematic really fast
if people are off frequency.  The 350 is a big improvement over the 500.  If
you do a lot of CW, maybe you want the 250, but for RTTY, I'd get the 350.
