- When operating RTTY, be sure respect the band guards around the IBP/NCDXA beacon
10 meters – 28080.5 to 28100 kHz, during contests 28080.5-28200 kHz (JA 28070-28200 kHz). (Note: PSK operation around 28120 KHz).
- Avoid 28199.5-28200.5 KHz (NCDXF/IARU frequency 28200 kHz).
12 meters – 24910 to 24930 kHz with most activity around 24920 kHz (JA 24910-24940 kHz).
- Avoid 24929.5-24930.5 kHz (NCDXF/IARU frequency 24930 kHz).
15 meters – 21080.5 to 21100 kHz, during contests 21080.5-21150 kHz (JA 21070-21150 kHz) (note: PSK31 operations around 21070-21072 kHz). Avoid 21149.5-21150.5 kHz (NCDXF/IARU frequency 21150 kHz).
17 meters – 18100 to 18110 kHz with occasionally operations below 18100 but above 18090 KHz (JA 18090-18120 kHz). Note: It is illegal for USA stations to operate RTTY above 18110 KHz.
- Avoid 18109.5-18110.5 KHz (NCDXF/IARU frequency 18110 KHz).
20 meters – 14080.5 to 14100 kHz, during contests 14080.5-14150 kHz (JA 14070-14150 kHz). (Note PSK31 around 14070-14072 kHz).
- Avoid 14099.5-14100.5 kHz (NCDXF/IARU frequency 14100 kHz).
30 meters – 10120 to 10150 kHz, with most operation around 10140 kHz (JA 10130-10150 kHz).
40 meters – 7025 to 7050 kHz and 7080 to 7100 kHz, during contests 7025-7100 kHz (JA 7030-7100 kHz). (USA stations are also allowed RTTY between 7100-7125 kHz).
80 meters – 3580 to 3600 kHz (JA 3520-3575 kHz), during contests 3570 (or lower)-3600 kHz. (RTTY operation above 3600 KHz is not permitted in the USA).
160 meters – 1800 to 1810 kHz. (JA 1907.5-1912.5 kHz) 1800 to 1810 kHz. (JA 1907.5-1912.5 kHz) Europe cannot operate below 1810 kHz. Region 1 (Europe, Africa, Middle East & Northern Asia) band plan suggests 1838-1843 kHz.
