I found I couldn't get away with any other framing as you can sometimes do with real modem hardware, i.e. As seen in the screenshot below I used shift=170, baud=45.45, framing=5N1.5, encoding=ITA2, not inverted. Sure enough, I was able to tune some contest RTTY on 40m using a Kiwi in The Netherlands. Although these functions are not currently documented. With some skill you can use the "scope" and "framing" functions from the mode menu, instead of "decode", to help narrow down the correct baud and framing values (just like the "baud error" indicator helps select the correct baud rate). I don't know that much about ham use but I believe the old-time RTTY stuff is more likely to be 5N1 or 5N1.5 and ITA2 as the encoding. See the "Weather, Maritime, Military, Utility" menus. That's why the FSK extension has a number of example signals that you can tune (using a Kiwi in an appropriate location, mostly Europe). But that's partly because decoding FSK signals is frustrating unless you know most of the many transmission parameters involved. Thank you, too, for your support of these sites.Yes, the FSK extension is frustrating to use. This configuration will let me click on a signal in the panadapter and watch it decode in the DI window. I also have disabled 'Turn Auto TRXUpdate On' option.
it does all the popular digital mode except for jt65, ft8, js8-call (for which wsjtx is there pipe program) if you check the rxid box in the top right it will very often detect the digital mode automatically.

If you’ve roamed the bands for RTTY signals you’ll find that most are encrypted with a few exceptions, one of which is WLO which is transmitting continuously. These are most commonly used by amateur radio ops too. The RTTY ( Radio Tele TYpe) parameters used by WLO transmissions are 45.45 bauds, 170Hz shift.
Those of you who are neophytes to RTTY or just want to dabble then this is the place to be to try your hand at an old and venerable digital mode. Joined Messages 24,365 Location Bowie, Md. Any suggestions would be greatly appreciated.

I am looking for software that will decode rtty and cw with a sdr-rtl (it can receive HF) dongle using the sound card and at this point have gotten no where.

Many thanks to SWLing Post contributor, Mario Filippi (N2HUN) for the following guest post: YouTube user ukasz Kosson has uploaded a video showing how he was able to decode RTTY signals on 10m (28 MHz).
