RTTY Subbands

The HF RTTY sub-band boundaries are defined and limited by your license.  Below are approximations of "normal" operating RTTY sub-bands world-wide.  When operating RTTY, be sure respect the band guards around the IBP/NCDXA beacon frequencies noted below.  For a detailed frequency band for IARU Region 2, see http://www.iaru-regionii.org/Region_2_HF_Band_Plan.html.  For USA licensed frequencies, see http://www.arrl.org/FandES/field/regulations/allocate.html and for USA band plan, see http://www.arrl.org/FandES/field/regulations/bandplan.html.

10 meters - 28080 to 28100 KHz, during contests 28060-28150 KHz.  (note:  PSK operation around 28120 KHz).  Avoid 28199.5-28200.5 KHz (IBP/NCDXA frequency 28200 KHz).

12 meters - 24910 to 24930 KHz with most activity around 24920 KHz.  Avoid 24929.5-24930.5 KHz (IBP/NCDXA frequency 24930 KHz).

15 meters - 21080 to 21100 KHz, during contests 21060-21150 KHz (note:  PSK31 operations around 21070-21072 KHz).  Avoid 21149.5-21150.5 KHz (IBP/NCDXA frequency 21150 KHz).

17 meters - 18100 to 18110 KHz with occasionally operations below 18100 but above 18090 KHz.  Note:  It is illegal for USA stations to operate RTTY above 18110 KHz.  Avoid 18109.5-18110.5 KHz (IBP/NCDXA frequency 18110 KHz).

20 meters - 14080 to 14100 KHz, during contests 14060-14140 KHz (note MFSK16 operations around 14080-14082, PSK31 around 14070-14072 KHz).  Avoid 14099.5-14100.5 KHz (IBP/NCDXA frequency 14100 KHz).

30 meters - 10120 to 10150 KHz, with most operation around 10140 KHz.

40 meters - 7025 to 7050 KHz and 7080 to 7100 KHz, during contests 7025-7100 KHz (USA stations are allowed RTTY between 7100-7125 KHz).

80 meters - 3580 to 3600 KHz (JA 3520-3525 KHz), during contests 3570 (or lower)-3600 KHz. (RTTY operation above 3600 KHz is not permitted in the USA).

160 meters - 1800 to 1820 KHz (RTTY is very rare on 160 meters).
