It is wise to leave a good margin to ensure that sidebands, etc do not spread onto this frequency. However great care must be exercised when operating at the top end of this section to ensure that no interference is caused to the beacons on 14.100 MHz.

On the 20 metre ham radio band, RTTY activity can be found at the top end of the Morse or CW section of the band between frequencies of 14.080 and 14.099 MHz. In view of the restrictions of the band, what activity there is can be found between frequencies of 10.110 and 10.150 MHz. In the USA, RTTY is permitted between 70, although most US activity is between 70. RTTY allocations for 40 metres vary greatly around the world in view of the different amateur radio band allocations. RTTY operation is typically found on frequencies between about 3.58 and 3.65 MHz although there are variations for some countries including Japan. It is also necessary to avoid the CW DX window between 1.830 and 1.840 MHz. 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 kHz. A rough summary of RTTY frequencies is given in the table below:įrequencies where RTTY transmissions can be found. 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 kHz 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.
