Committee C.4 DOC/96/TAI/C4.9
Revision 1
IARU REGION 1 HF BAND PLAN (part 2 of 2)
===========================================
REMARKS:
Where several modes are shown in the sub-bands the first has priority.
But this has to be exercised on a Non-interference Basis (NIB) according
to the ITU Radio Regulations.
A mode written in brackets () means "preferred area of activity".
The expression RTTY shall be replaced by the expression DIGIMODE. The
expression "digimode" includes all modes of this form of transmission.
(e.g. Baudot/RTTY, AMTOR, PACTOR, CLOVER, ASCII, Packet Radio).
The expression "phone" includes all modes of this form of transmission.
Up to 10 MHz LSB and above USB should be used on HF bands.
1.8 MHz band:
Those Societies which have an existing SSB allocation below 1840 kHz may
continue to use it. However, they are requested to take all necessary steps
with their licensing Administrations to adjust the phone allocations in
accordance with the Region 1 Band Plan.
3.5 MHz band: 3500 - 3510 kHz and 3775 - 3800 kHz:
Intercontinental operation should be given priority in these segments.
Contest Preferred Segments:
Where no DX traffic is involved, the contest preferred 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).
This recommendation does not apply to digimode stations. Contest activity
shall not take place on the 10, 18 and 24 MHz bands.
7 and 10 MHz band:
The use of Packet Radio is discouraged on 7 and 10 MHz band. The band seg-
ment 7035 - 7045 kHz may be used for store-and-forward traffic in the area
of Africa south of the equator during local daylight hours. However, the
use of more efficient modes than the AX.25 packet radio are encouraged.
10 MHz band:
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.
It is recommended that unmanned stations using digital modes shall avoid
the use of the 10 MHz band.
The bandsegment 10120 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.
SSTV/FAX:
The frequencies 14230, 21340 and 28680 kHz should be used as calling
frequencies for SSTV and FAX operators. After having established contact,
they should move to another free frequency within the telephony portion of
the band.
Satellite operation frequencies:
Member Societies should advise FM (and other) operators not to transmit on
frequencies between 29.3 and 29.51 MHz in order to avoid interference to
amateur satellite downlinks.
Unmanned transmitting stations:
IARU Member Societies are requested to limit this activity on the HF bands.
It is recommended that any unmanned transmitting station on HF shall only
be activated under operator control except for IARU approved beacons or
specially licensed experimental stations.
Transmitting Frequencies:
The announced frequencies in the Band Plan are understood as "transmitting
frequencies" (not those of the suppressed carrier!).
Experimentation with NBFM Packet Radio on 29 MHz Band:
Preferred operating frequencies on each 10 kHz from 29210 to 29290 kHz incl.
should be used. A deviation of +/- 2.5 kHz being used with 2.5 kHz as maximum
modulation frequency.
Footnotes:
Footnotes to the HF Band Plan should be avoided.
National Societies are requested to advise their members to follow this Band
Plan.
