This is not intended to be an “etched in stone” indication of how to operate a RTTY contest, so please don’t take it that way! Whatever works the best for you, is what you should do, as long as it allows your participation to be fun! These hints were obtained from RTTY contesters, world wide, and only reflect how they try to make their operation more efficient! The more efficient “we” make our contest exchanges, the more efficient we make it for all involved! Band conditions certainly play an important part in the exchanged data, so establishing a “different” buffer could make your exchange more efficient in “not so good” band conditions! I’ve archived a copy that I believe could be usefull for beginners. This document was originally posted by K4WW on but this domain has expired since some months at time writing. RTTY allocations for 40 metres vary greatly around the world in view of the different amateur radio band allocations.ISBN: It is also necessary to avoid the CW DX window between 1.830 and 1.840 MHz.
A rough summary of RTTY frequencies is given in the table below: There is little RTTY activity on this band, but what little there is can usually be found on frequencies between 1.800 and 1.820 MHz, although in many countries the bottom end of the band is 1810 k Hz. However this is not true in all cases because the different amateur radio bands have different bandwidths and also the requirements may be slightly different.
the frequencies where amateur RTTY transmissions can be found are between 80 and 100 k Hz above the bottom end of each band. Typically the radio teletype, RTTY frequencies, i.e. In view of the fact that the amateur radio bands are planned so that different modes are restricted to particular areas to reduce interference and ensure the optimum use of each band, so RTTY can be found in particular areas of the HF amateur radio bands.
