Bandplanning between 10.100 and 10.150 MHz
10 MHz
SSB may be used during emergencies involving the immediate safety of life and property and only by stations actually involved in the handling of emergency traffic.
News bulletins on any mode should not be transmitted on the 10 MHz band.
DEFINITIONS
Narrow band modes All modes using up to 500 Hz bandwidth, including CW, RTTY, PSK etc.
Digimodes Any digital mode used within the appropriate bandwidth, for example RTTY, PSK, MT63 etc.
(*) Lowest dial setting for LSB Voice mode: 1843, 3603 and 7053 kHz.
NOTES
CW QSOs are accepted across all bands, except within beacon segments. (Recommendation DV05_C4_Rec_13).
Contest activity shall not take place on the 10, 18 and 24 MHz bands.
The term “automatically controlled data stations” includes Store and Forward stations.
Unmanned transmitting stations:
Sideband Usage Below 10MHz use lower sideband (LSB), above 10 MHz use upper sideband (USB).

| FREQUENCY (kHz) |
MAX BAND1WIDTH (Hz) |
PREFERRED MODE AND USAGE |
| 10100 - 10140 | 200 | CW, 10116 kHz - QRP Centre of Activity |
| 10140 - 10150 | 500 | Narrow band modes – digimodes |
SSB may be used during emergencies involving the immediate safety of life and property and only by stations actually involved in the handling of emergency traffic.
The band segment 10120 kHz to 10140 kHz may be used for SSB transmissions in the area of Africa south of the equator during local daylight hours.
News bulletins on any mode should not be transmitted on the 10 MHz band.
DEFINITIONS
All modes CW, SSB and those modes listed as Centres of Activity, plus AM (Consideration should be given to adjacent channel users).
Image modes Any analogue or digital image modes within the appropriate bandwidth, for example SSTV and FAX.
Narrow band modes All modes using up to 500 Hz bandwidth, including CW, RTTY, PSK etc.
Digimodes Any digital mode used within the appropriate bandwidth, for example RTTY, PSK, MT63 etc.
(*) Lowest dial setting for LSB Voice mode: 1843, 3603 and 7053 kHz.
NOTES
Amplitude modulation (AM) may be used in the telephony sub-bands providing consideration is given to adjacent channel users. (NRRL Davos 05).
CW QSOs are accepted across all bands, except within beacon segments. (Recommendation DV05_C4_Rec_13).
Contest activity shall not take place on the 10, 18 and 24 MHz bands.
Non-contesting radio amateurs are recommended to use the contest-free HF bands (30, 17 and 12m) during the largest international contests. (DV05_C4_Rev_07).
The term “automatically controlled data stations” includes Store and Forward stations.
The frequencies in the bandplan are understood as “transmitted frequencies” (not those of the suppressed carrier!).
Unmanned transmitting stations:
IARU member societies are requested to limit this activity on the HF bands. It is recommended that any unmanned transmitting stations on HF shall only be activated under operator control except for beacons agreed with the IARU Region 1 beacon coordinator, or specially licensed experimental stations.
Sideband Usage Below 10MHz use lower sideband (LSB), above 10 MHz use upper sideband (USB).
