Welcome to Australia Narrowband Broadcast Radio -

ACMA Types of Broadcast licensing


Our messageboard forum is located at the bottom of the page

This is the place for people interested in the Australian Radio "off-band" sector
as well as providing a resource for sharing useful information on broadcast radio licensing options in Australia.

The main categories of broadcast radio licensing that we focus on are:-
VHF Narrowband Area Service (NAS) stations
MF Narrowband Area Service (NAS) stations
VHF FM LPON Low Power Open Narrowcast stations
HF Domestic shortwave stations

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 FM

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 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.

MEDIUMWAVE AM

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

Mediumwave 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.

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
ACMA LPON VHF FM Link

SHORTWAVE

HF Domestic Broadcasting stations
Shortwave AM - 6 KHz bandwidth 400 ~ 1000 watts transmitter power
Bands that may be used for HF domestic broadcasting

Frequency range (kHz)
2 300 - 2 495
3 200 - 3 400
3 950 - 4 000
4 750 - 4 995
5 005 - 5 060

Currently ACMA have allocated the following frequencies to HF Domestic stations:
2355, 2368.5, 3210, 5050 KHz.

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 for legal use in Australia

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 NAS LIPD bands

VHF NAS LIPD 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)
