The following band plan
is largely based on that agreed at IARU Region 1 General Conferences with
some local differences on |
|
|
|
on frequencies above 430
MHz. |

Notes to the Band Plan |
|
|
|
ITU-R Recommendation
SM.328 (extract) |
|
|
Necessary
bandwidth: For a given class of emission, the width
of the frequency band which is just sufficient to |
|
|
ensure the transmission of
information at the rate and with the quality required under specified
conditions. |
|
|
|
The use of Amplitude
Modulation (AM) is acceptable in the all modes segments but users are asked
to consider |
|
|
adjacent
channel activity when selecting operating frequencies. |
|
|
|
Foundation
and Intermediate Licence holders are advised to check their licences for the
permitted power limits and |
|
|
conditions applicable to their class
of licence. |
