Shown here are the UK licence conditions, and national and international
band plans for most amateur bands. The licence conditions are for guidance
only, are subject to change and must be read in conjunction with the
appropriate RA booklet for your class of licence. These band plans,
including any updates, will be published in the RSGB Yearbook 2003 Edition.
Note that the power levels shown in these band plans are for the UK Full
licences. Intermediate Licensees are limited to 50W PEP, while Foundation
Licensees are limited to 10W PEP. Intermediate and Foundation licence
holders should refer to their appropriate RA licence booklet for full
details.
Notes to the HF
Band Plans
1. The word ‘phone’
includes all permitted forms of telephony.
2. If transmitting very close to a band edge, take care not to radiate
outside of the band.
3. Before transmitting, all operators should check that the frequency is not
already occupied. The normal advice is to use the question “Is this
frequency in use?” on SSB or “QRL?” using Morse.
4. *Machine Generated Modulation (MGM) are defined as including AmTOR,
PacTOR, Clover, ASCII, RTTY (Baudot), PSK31 and AX25 packet.
5. LSB is recommended on bands below 10MHz, and USB on bands above 7MHz.
6. The Region 1 IARU HF band plans are designed to enable the best
utilisation of the HF spectrum space available. They achieve this objective
because the vast majority of licensed amateurs observe the voluntary
recommendations. In some countries (eg the USA), licence regulations require
that specific modes be confined to specific sections of each band.
7. The frequencies 14.230, 21.230 and 28.680MHz 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 section of
the band.
* The designation 'Machine
Generated Modulation’ (MGM) replaces the Digimode’ designation.
Notes on the VHF
Band Plans
1. The beacon and
satellite services must be kept free of normal communication transmissions
to prevent interference with these services.
2. The use of the FM mode within the SSB/CW section and CW and SSB in the
FM-only sector is not recommended.
3. Repeater stations are primarily intended as an aid for mobile working and
they are not intended to be used for DX communication. FM stations wishing
to work DX should use the all-modes section, taking care to avoid
frequencies allocated for specific purposes.
Unattended (U/A)
Operation
Frequencies on which
unattended (U/A) operation is permitted are shown in these band plans.
Remember that unattended operation requires the prior consent of the local
Radio Investigation Service before operation can begin, to enable close down
arrangements to be made.
Unattended beacons are limited to 14dBW ERP max. Do not confuse this type of
unattended beacon operation with the normal beacon sections of the bands
(these are fully site cleared, have special licences and are co-ordinated on
an international basis.
Unattended low power remote control is limited to -20dBW ERP and should not
radiate outside the boundary of the premises from which you are operating.
Unattended digital operation is limited to 10dBW on the 50MHz band and 14dBW
on the other bands where it is permitted. |
