Not using the dual pass-band mode, due to the degradation Rich notes, is
the consensus of some of the best RTTY contest operators of our
acquaintance.

In RTTY (FSK D or AFSK A), the Dual PB button gives you a dual peak
filter peaked on the two tones of the RTTY signal. In theory, this
actually degrades the performance of a well-designed demodulator, so
you might be better off not using it routinely, but in the situation
where there are two overlapping RTTY signals with the mark or space of
the interfering signal in between the mark and space of the one you
are trying to work, it may help reduce the interference.
