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

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.

Amateurs in countries that have a SSB
allocation ONLY below 1840 kHz, may
continue to use it, but the National Societies in
those countries are requested totake all necessary
steps with their licence administrations to adjust
the phone allocations in accordance with the
Region 1 Bandplan. (Davos 2005) |

Intercontinental
operations should be given priority in the
segments 3500-3510 kHz and 3775-3800 kHz. |
|
Where
no DX traffic is involved, the contest segments
should not include 3500-3510 kHz or 3775-3800 kHz.
Member societies will be permitted to set other (lower)
limits for national contests (within these limits). |
|
3510-3600
kHz may be used for unmanned ARDF beacons (CW ) (Davos
2005) |
|
Member
societies should approach their national
telecommunication authorities and ask them not to
allocate frequencies to other than amateur
stations in the band segment that IARU has
assigned to intercontinental long distance traffic. |

Member
societies should advise operators not to transmit
on frequencies between 29.3 and 29.51 MHz to avoid
interference to amateur satellite downlinks. |
|
Preferred
NBFM operating frequencies on each 10 kHz from
29.210 to 29.290 MHz inclusive should be used. |
|
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) |
