Band Plan Update

Band plan news

CHANGES TO THE 2 METRE BAND PLAN

Changes have been adopted for frequencies between 144.700 and 145.800 MHz. These changes include rearrangement of simplex channels and the provision of extra repeater allocations for use in cases where none of the regular channels is available.

Existing legacy repeater, IRLP and AX25 licences allocated prior to September 2015 may remain on their existing frequencies until the licensees choose to initiate a frequency change. Some long established special purpose simplex frequencies (e.g. ARDF) may also need to remain for some time.

Full details of the band plan changes are available in the "Files for Download" section.

CHANGES TO THE 70 cm BAND PLAN

Please note the band plan changes which have been adopted for the purpose of overcoming interference problems caused by LIPD (“Low Interference Potential” devices) in the band 433.050 - 434.790 MHz. These changes include rearrangement of simplex channels and the creation of a new repeater input segment.

Existing legacy repeater, IRLP and AX25 licences allocated prior to September 2015, and some long established special purpose simplex channels may remain on their existing frequencies until the licensees choose to initiate a frequency change.

Full details of the band plan changes are available in the "Files for Download" section.

RESTRICTIONS ON 3.4 GHz OPERATION

From July 2015, operation on frequencies between 3400 and 3575 MHz is prohibited in many parts of Australia (basically all major population centres). However operation is still permitted in country and remote areas. For full details, please refer to the latest ACMA Amateur Licence Conditions Determination.

The main impact is on the Narrow Band Modes segment. To avoid any confusion about where operation should take place, it is recommended that all weak signal activity should move to 3398 MHz.

Recent band plan changes

Over the last couple of years ....

2200 Metres

Please refer to the band plans for an interim plan for the 2200 metre (135.7 - 137.8 kHz) band.

630 Metres

The band plan has been updated with additional detail added. Full details are in the "Files For Download" section.

The following frequencies are based on current CW and digital activity in IARU Region I, and are recommended for DX activity.

CW 472.500 kHz - recommended centre frequency for international DX
WSPR 474.2 kHz USB dial frequency (occupied bandwidth 475.6 - 475.8 kHz)
ROS 476.0 kHz USB dial frequency (occupied bandwidth 477.4 - 477.6 kHz)
QRSS 476.175 kHz USB dial frequency (occupied bandwidth 477.175 - 477.185 kHz).
(Some activity also on 478.9 kHz)
WSJTX 477.0 kHz USB dial frequency (occupied bandwidth 478.0 - 478.5 kHz)
Opera 477.0 kHz USB dial frequency (occupied bandwidth 478.5 - 478.8 kHz)

SSB operation is also permitted, with a maximum occupied bandwidth of 2.1 kHz. However it is not possible to run SSB without overlapping frequencies that are used for CW or digital modes. Users of this band will need to exercise tolerance and restraint. One suggested approach is that SSB operators voluntarily restrict their activities to daylight hours.

The two SSB frequencies listed below are possible options that have been suggested. The frequencies given assume the use of LSB mode and an audio bandwidth of 300 - 2400 Hz.
 479.3 kHz LSB dial frequency (occupied bandwidth 476.9 - 479.0 kHz).
 476.0 kHz LSB dial frequency (occupied bandwidth 473.6 - 475.7 kHz).

HF Bands - Recommended IARU Region III centre frequencies for emergency operation

IARU Region III has adopted the following frequencies as recommended emergency centre of activity frequencies: 3.600, 7.110, 14.300, 18.160 and 21.360 MHz. As an IARU member society, the WIA has adopted these recommended frequencies.

"Centre of Activity" frequencies are not spot frequencies or net frequencies. They are recommended as starting points for emergency traffic which may extend 5 kHz above or below the designated centre frequency.

6 Metres

The 6 metre band plan has had some additions:

50.000 - 50.030 MHz - Reserved for future international Synchronised Beacon Project
50.240 - 50.280 MHz - Recommended for Chirp beacons with bandwidths 2 - 20 kHz.
50.320 - 50.400 MHz - Reserved for upward expansion of the beacon segment.
50.400 - 50.500 MHz - Reserved for propagation studies:
Guard band for proposed new Region I beacon segment.
Recommended for Chirp beacons with 20 - 100 kHz bandwidth.
50.500 -52.000 MHz - Still tagged "All Modes" for maximum future flexibility. Possible use of all or part when the availability of the full 50 - 54 MHz band is confirmed. Digital ATV may be possible in this segment provided the occupied bandwidth limits in the LCD are increased.

Any comments on future uses of the band are most welcome.

Revised CTCSS Standards

Changes were made to the standard CTCSS tones to be used for repeater access and linking.

Our licence conditions require tone access for repeaters that are linked to repeaters in certain other bands, to prevent transmissions from being relayed on frequencies that the operators are not entitled to use. CTCSS is also used to activate selective linking or for interference protection.

The following CTCSS tones have been adopted for repeater access:
 91.5 Hz: For use with repeaters fitted with CTCSS for interference protection.
 141.3 or 146.2 Hz: To activate links to repeaters on other VHF/UHF bands.
 85.4 Hz: To activate links to other bands that some operators are not permitted to use.
The previously recommended 123 Hz tone is no longer recommended for future repeaters due to problems with false detecting.

ATV Updates

The band plans were updated to include revised standards for DVB tranmssion.
