I have been active on RTTY since the 1960s, and was instrumental in introducing AmTOR to amateur radio at the end of the '70s. This improved the reliability of the HF radio link and paved the way to further developments which have taken this side of the hobby more into data transfer, message handling, and computer linking, but further away from the rest of amateur radio which is.based on two-way contacts between operators. There is now a gap opening up between the data transfer enthusiasts using the latest techniques and the two-way contact fans who are still using the traditional RTTY mode of the '60s, although of course using keyboard and screen rather than teleprinter. There is scope for applying the new techniques now available to bring RTTY into the 21st century.
