It is often the case when Data modes cannot be decoded they are visible on the waterfall display. It is also a fact that RTTY can easily be visually read on a waterfall display when it does not decode/print because of qrn hits or qsb.
In the past RTTY fsk marks/spaces were read from undulator tape by a competent operator who knew the Murray code. This method produced better results than direct demodulation/printing
The preferred method on LF/MF surely is QRSS, DFCW for reliability in handling very weak signals then CW for the stronger signals and local working.

Did the program show that decode on your PC? On my PC the decode did not appear! It would be a pity if decodes would be lost. I tried to reach UZ2HZ but thought i wasn't successful. Maybe it was the same with SM2DJK?
Maybe further stations got successful TA decodes but no one knows? Another disadvantage compared to QRSS/DFCW..
