[RTTY] Trouble with MMTTY

[allan1 at dejazzd.com]

I am using the Icom 756 PRO 111 with built-in  FSK along with MMTTY which I have been using together for a few years.  This morning when I tried RTTY the two X-Y graphs were not normal.  Normally I would see a bell curve, but instead it is showing straight noise about 5 mm above the base line even when I tune in a station which the PRO 3 is decoding.  Again, normally when a station is tuned in there are two perpendicular ellipses in the box adjacent to the X-Y graph.  Now I get what looks like a star burst (small) which doesn't change when I tune in a station.

Anyone have any thoughts on how to fix this-would be very much appreciated.

Thanks
