Note
1: Meteor scatter operation can take place up to 26kHz
higher than the reference frequency. |
|
|
Note
2: 12.5kHz channels numbered RV48-RV63. RV48 input =
145.000 MHz, output=145.600 MHz. |
|
|
Note
3: 12.5kHz simplex channels numbered V16-V47. V16=145.200 MHz. |
|
|
Note
4: Emergency Communications Groups utilising this
frequency should take steps to avoid interference to ISS operations |
|
|
in non-emergency
situations. |
|
|
Note
5: Embedded data traffic is allowed with digital voice
(DV) |
|
|
Note
6: Simplex use only - no DV gateways |
|
|
Note
7: EME activity using MGM is commonly practised between
144.110-144.160 MHz |
|
|
Note
8: Amplitude Modulation (AM) is acceptable within the All
Modes segment. AM usage is typically found on 144.550MHz. |
|
|
Users should consider adjacent
channel activity when selecting operating frequencies |
|
|
Note
9: In other countries IARU Region-1 recommend 145.375 MHz |
|
|
Note
10: May be used for Emergency Communications and Community
Events |
|
|
Note
11: May be used for repeaters in other IARU Region-1
countries |
|
|
Note 12: DV users are asked not to use
this channel, and use 144.6125 MHz for calling. |
|
|
Note 13: not used |
|
|
|
|
Note 14: 144.800 use should be NBFM to
avoid interference to 144.8125 DV Gateways |

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. |
