Andy, I have had a registered copy of TruTTY for years and it constantly outperforms any other program for RTTY. I also think the MFSK-16 and PSK31 implementations are excellent too. Well worth the money if you need a simple to operate, processor non-intensive application. It also interfaces to AALog3 which makes it very useful.
For those interested in SW monitoring the SeaTTY program also has excellent performance on Navtex, GMDSS and HF fax. Patrick's MultiPSK fax decoding is slightly better I think but the automatic logging facility of SeaTTY is fantastic. For weak signal Morse then Norbert's MRP40 is unrivaled. If you've never tried this program then download the demo and try it. Sholto K7TMG
