This is also possible in N1MM when using the MMVARI Engine. Up to 24
channels of decoded text but works best with 10 or less because of number of
stations in the frequency width..

Hi Bill
pse try "MULTIPSK RTTY Panoramic"
<http://f6cte.free.fr/multipsk_e.htm>
>RTTY (45 bauds) Panoramic reception of 8 QSO maximum on 22 channels.
AF (200 to 3800Hz) band width
limited to 5minutes for un-licensed version
but it's working well and become good impression for me.
