some local differences on |
|
|
on frequencies above 430

|
Note 1:
Local traffic using narrow band modes should operate between
1296.500-1296.800 MHz during contests and band openings. |
|
|
Note 2: Stations in countries that do not have
access to 1298-1300 MHz may also use the FM simplex segment |
|
|
for digital
communications. |
|
|
|
Note 3: IARU Region 1 recommended maximum bandwidth
is 20 kHz. See also Note-7 |
|
|
Note 4: deleted |

|
|
|
Note
5: Embedded data
traffic is allowed with digital voice (DV) |
|
|
Note
6: Simplex use only
- no DV gateways |
|
|
Note
7:
1240.000-1240.750 has been designated by IARU as an alternative centre
for narrowband activity and beacons |
|
|
Operations in this range
should be on a flexible basis to enable coordinated activation of this
alternate usage |
|
|
Note
8: The band 1240-1300MHz is subject to
major replanning. Contact the Microwave Manager for further information |
|
|
Note
9: Repeaters and
Migration to DATV, inc option for new DATV simplex are subject to further
development and coordination |

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. |
