| FREQUENCY (kHz) | MAX BANDWIDTH (Hz) | PREFERRED MODE AND USAGE |
| 135.7 – 137.8 | 200 | CW, QRSS and narrow band digital modes |
| RR 5.67A Stations in the amateur service using frequencies in the band 135.7-137.8 kHz shall not exceed a maximum radiated power of 1 W (e.i.r.p.) and shall not cause harmful interference to stations of the radionavigation service operating in countries listed in No. 5.67. (WRC-07) (Cavtat 2008) |
| RR 5.67B The use of the band 135.7-137.8 kHz in Algeria, Egypt, Iran (Islamic Republic of), Iraq, Libyan Arab Jamahiriya, Lebanon, Syrian Arab Republic, Sudan and Tunisia is limited to the fixed and maritime mobile services. The amateur service shall not be used in the above-mentioned countries in the band 135.7-137.8 kHz, and this should be taken into account by the countries authorising such use. (WRC-07)(Cavtat 2008) |

| A deviation of ±2.5 kHz being used with 2.5 kHz as maximum modulation frequency. |
| 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) |
