Jim, If you have not set up the RTTY filters and BFOs (I think that you have not from your description), then do that first and it should set things straight.
I usually set the RTTY filters as follows: FL1=OP1, with the BFOs set the same as those for SSB (RTTY = LSB and RTTYr = USB). FL2=1.00, FL3=0.80, FL4=0.40 with the BFOs set to position the passband centered at 1000 Hz. With those settings, tune the station of interest to (or near) 1000 Hz using FL1, then when the station is selected, lock the transmit frequency in the software. Now you can narrow the filters by tapping XFIL if a strong station comes on nearby and tries to take over the receiver AGC. 73, Don W3FPR > -----Original Message----- > > I have encountered a problem using PSK31 in data mode with my K2.
