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

|
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. |
