ACMA Types of Broadcast licensing

Included are many useful Links to information pages located within the ACMA website.
The Australian Communications and Media Authority (ACMA) regulates broadcasting services in Australia.

VHF NAS (Narrowband Area Service) frequency bands

70.00000 to 70.24375 MHz
77.29375 to 77.49375 MHz
151.39375 to 152.49375 MHz
173.29375 to 174.00000 MHz

The technical parameters that apply to VHF NAS stations are:

a) a maximum Equivalent Isotropically Radiated Power (EIRP) of 83 watts; (50 watts transmitter power)
b) an emission bandwidth of 16 kHz (16K0F3E in a 25 kHz bandwidth channel) and
c) Radiocommunications Standard (Analogue Speech (Angle Modulated) Equipment) No. 1 of 1995.

Understanding how ACMA manage Frequency Assignment in the Land Mobile space.

ACMA Frequency Assignment in the Land Mobile space

VHF NAS station transmitters, in a technical sense, operate under similar arrangements to land stations in the Land Mobile licence type.


MF Narrowband Area Service (NAS) stations operate in the
Extended AM band over 11 channels in 9 kHz channel steps
Mediumwave Extended AM Radio Broadcast Band
1611 kHz 186 meters - 1701 kHz 176 meters

MF NAS (Narrowband Area Service) AM frequency channels
1611, 1620, 1629, 1638, 1647, 1656, 1665, 1674, 1683, 1692, 1701 KHz

The Extended AM radio broadcast band 1611 kHz - 1701 kHz

MF AM transmitter power 400 watts, bandwidth limited to 6 kHz.

400 watts pZ Carrier Power 'pZ' means the average power supplied to the
antenna transmission line by a transmitter during one radio
frequency cycle taken under the condition of no modulation.

The co-channel separation distance between transmitters is 160 km
and the 9 kHz adjacent channel separation distance between transmitters is 30 km.

MF and VHF NAS radio stations operate outside of the normal broadcast radio bands.

The MF (Mediumwave) NAS spectrum segment is in the Extended AM band of 1611 kHz (186 metres) - 1701 kHz (176 metres) in 9 kHz steps over 11 channels.

The VHF NAS spectrum segments are in the following mid and high VHF bands.
70, 77, 151/152 & 173 mHz bands using the standard radio communications emission mode 16K0F3E (FM) within a 25 kHz bandwidth channel.

It would also be possible to use an emission mode of 10K1F3E (NB-FM) within a 12.5 kHz bandwidth channel, although this is rare.

What is a NAS (Narrowband Area Service) station?

The operation of a NAS station is authorised by a radiocommunications apparatus licence
issued under the narrowband area service licensing option within the broadcasting licence type.

NAS stations are normally authorised to provide a service using non broadcasting services band frequencies.
NAS stations may operate in appropriate parts of the VHF (70, 77, 151/152, 173 mHz bands)
and MF (1611 kHz 186 metres to 1701 kHz 176 metres) frequency bands.

NAS stations are usually used to provide 'narrowcasting' programming (within the meaning of the Broadcasting Services Act 1992).
Narrowcasting services must have reception limited in some way (for example, by being targeted at special interest groups).
Such operation is authorised under a class licence issued, by the ACMA, under the BSA.

FM 87 - 88 MHz

VHF FM LPON stations
1 watt transmitter power (10 watts in low density areas)
87.6, 87.8, 88.0 MHz


HF Domestic Broadcasting stations

Currently ACMA have allocated the following frequencies to HF Domestic stations:
2310, 2325, 2350, 2355, 2368.5 kHz (120 meter band), 3210 kHz (90 meter band), 4835, 5045, 5050, 5055 kHz (60 meter band).

The L.I.P.D. Class Licensing

The LIPD Class Licence authorises users to operate a wide range of low power
radiocommunications devices operating in various segments of the radiofrequency spectrum.
The LIPD Class Licence sets out the conditions under which many types of short range devices may operate.
These conditions always cover frequency bands of operation and radiated power limits.

Low Interference Potential Devices are small low power radio transmitters that can be used without a licence
on certain frequencies because they are unlikely to interfere with other users.
Details of frequencies and power limits here:
Low Interference Potential Devices

Some of the bands allocated to LIPD are as follows:-

70.0000 70.24375 mHz 100 mW max RF power
77.29375 77.49375 mHz 100 mW max RF power
150.7875 152.49375 mHz 100 mW max RF power
173.29375 174.0000 mHz 100 mW max RF power

LIPD transmitters are authorised under an ACMA Class Licence -

This Class Licence authorises a person to operate a transmitter included in a class of transmitters
mentioned in an item in Schedule 1, subject to the following conditions:
(i) The transmitter must be operated: on a frequency, or within a range of frequencies, mentioned in the item; and
(ii) at a radiated power that does not exceed the maximum EIRP mentioned in the item; and
(iii) within the limitations (if any) mentioned in the item;

For the full details of the LIPD Class Licence please click on the following link
ACMA "The ACMA LIPD Class Licence"

SRK Electronics can build to order a fixed frequency LIPD VHF transmitter for use in one of the VHF LIPD and VHF NAS bands

70 mHz (4.2 metre band), 77 mHz (3.8 metre band), 151-152 mHz (1.9 metre band), 173 mHz (1.7 metre band)

Transmitter RF power output: 100 milli watts (LIPD max legal output)

Class licences

Class licences are issued by the Australian Communications and Media Authority (the ACMA).
Under a class licence, all users share the same spectrum segment and are subject to the same conditions.
A class licence governs equipment standards and the frequencies that may be used,
and can specify other technical and operational parameters.
Class licences do not have to be applied for, and no licence fees are payable.
