Band Plan Update
Band plan news
6 metre band plan
The 6 metre band plan has been reworded to clarify ACMA operating restrictions between 50 and 52 MHz.
Recommended IARU Region III centre frequencies for emergency operation
At its 2009 meeting, IARU Region III 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. They are recommended as starting points for emergency traffic which may extend 5 kHz above or below the designated centre frequency.
Proposed band plan changes
6 Metre APRS
A dedicated simplex channel for APRS is to be established in the 6 metre band. The frequency proposed is 53.050 MHz.
23 cm D-Star simplex channel
It is proposed to extablish a national simplex channel for 23 cm simplex operation (as distinct from the single frequency D-Star repeater gateways operating above 1298 MHz). The suggested frequency is 1297.500 MHz, in the existing Digital Simplex band segment.
Recent band plan changes
IRLP and Echolink
Band plan changes during the past year include recommended frequencies for simplex IRLP and Echolink gateways:
 2 metres - 145.325, 145.350, 145.375 and 145.400
70 cm - 439.150 and 439.175
D-Star Frequencies
To avoid co-channel interference between D-Star and analog FM operation, D-Star repeaters are being assigned to frequencies that are not used by FM repeaters.
The band plans also include details of recommended frequencies for simplex D-Star operation:
2 metres - 145.125 MHz.
70 cm - primary 438.900, secondary 439.8875 and 439.9125 (12.5 kHz spacing)
These recommended frequencies are subject to review as D-Star activity increases.
Revised CTCSS Standards
Changes have been 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.
LF Band
The band plans now include an interim plan for the 2200 metre (135.7 - 137.8 kHz) band.
