Quick Reference Chart

In the "Files for Download" section we now have a draft band plans chart, covering the bands from 160 metres to 70 cm. Updated version 4 July 2019.

FT8 Segments on 160 and 40 Metres

The 160 metre band plan has now been updated to recognise the use of 1840 - 1843 kHz for FT8 operation. And on 40 metres, the band plan now recognises the use of 7074 - 7080 kHz for FT8 activity.

There have also been some interference issues between FT8 operation on 7074 kHz (USB) and WICEN voice activity on 7075 kHz LSB. The logical remedy, at least for now, is to move the recommended WICEN frequency down 1 kHz to 7074 kHz LSB. However this is not a permanent cure because digital activity is constantly increasing and 7070 - 7080 kHz is being used for digimodes in Region II. Our band plan needs to be aligned with IARU Region III, but we also need to avoid clashes for stations working into other regions. So this issue will need further consideration.

In the longer term, WICEN groups may wish to consider making use in the future of the IARU Region III recommended emergency frequency of 7110 kHz. This is in the internationally agreed SSB segment and is a comfortable distance away from the band segments being used by digimode stations.

70cm Digital ATV Repeaters

The 70 cm band plan has been amended to allow digital ATV repeaters to operate 1 MHz lower in the band, occupying a channel at 442 - 449 MHz.

A DATV signal occupies a full 7 MHz bandwidth with virtually no guard band, and filtering under these conditions is quite a challenge. This has resulted in interference between DATV operation and other services immediately above 450 MHz. By moving the DATV channel down, we gain a 1 MHz guard band for DATV, and also a new segment for links at 449 - 450 MHz.

Existing 442 MHz links can in most cases stay on their current frequencies, but some in the service areas of DATV repeaters may need to move down to 440 MHz or up to 449 MHz. AM ATV repeaters can also remain, but as they change over to DATV they should convert to a channel centre frequency of 445.500 MHz.

Beacons and FT8

The Barossa Valley 6 metre beacon VK5RBV has been switched off, to avoid interfering with stations running FT8. VK5RBV has been operating for many years on 50.315 MHz, but the developers of FT8 have nominated a worldwide operating frequency of 50.313 MHz, so VK5RBV will need to be relocated. It is also likely that similar clashes could occur in the future as more new digital modes come into use in the same part of the band.

The placement of our 6 metre beacon segment - centred on 50.300 MHz - was dictated by our licence conditions in the days of Channel 0 television. Below 52 MHz, operation in the eastern states was confined to the DX window at 50.000 - 50.300 MHz. So eastern state beacons were allocated just below 50.300 MHz, and western state beacons just above 50.300 MHz. But now we can progressively relocate our beacons as and when necessary to avoid any future clashes with digimode activity.

The sub-band 50.300 - 50.400 MHz is now recognised as digimode territory in all IARU regions. And 50.400 - 50.500 MHz has been adopted in Region I as the new recommended beacon segment. We will over time be able to follow the same pattern, and the existing band plan already makes provision for this.

FT8 on 2 metres

FT8 is becoming popular on 2 metres. The software comes with recommended operating frequencies built in, but only for bands up to 6 metres. On 2 metres, our band plan has a group of spot frequencies recommended for modes of different bandwidths. The narrow band channel on 144.320 MHz is the logical one for FT8. It is noted that 144.313 MHz has also been used for FT8. But unless there are compelling reasons to do otherwise, I would recommend the band plan.

HF Bands Digital Segments

The proposed changes to the HF digimode segments have now been made. This brings our digital band plans into line with the IARU Region 1, 2 and 3 plans. See the "Files for Download" section.

SSB on 30 Metre Band

Australia is almost unique in the world in allowing SSB operation on 30 metres. In other countries, the only permitted modes are CW and narrow band digital modes. The result is interference between CW and SSB stations. The only possible solution is co-operation and restraint. To reduce the likelihood of interference, it is recommended that SSB stations operate above 10.125 MHz whenever possible.

November 2017 Update

The 160 metre band plan now shows the digital mode segments applying in IARU Regions I, II and III. There has also been an update to the list of special purpose frequencies used internationally on the LF, MF and HF bands. Some of these frequencies differ from those in the Australian or IARU band plans. They are listed for information only and are not intended to be prescriptive.

Band plan changes in the past year


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.


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.

Recent band plan issues

Over the past couple of years, in order of frequency

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 below: Background - 630 metres 2014.pdf

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 IARU 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 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.

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 have been updated to include revised standards for DVB transmission.


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, all weak signal activity has moved to 3398 MHz.
