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/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 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.

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 LIPD and VHF NAS bands VHF 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) Transmitters for the 100 milli watt VHF NAS LIPD bands - go to SRK Electronics VHF NAS LIPD Transmitters Latest reports from the ACMA’s Field Operations staff ACMA "In The Field" Broadcast Licensing ACMA Broadcast Licensing ACMA Spectrum Search Register ACMA Spectrum Search Link ACMA Apparatus License Fee Calculator ACMA Apparatus License Fee Calculator Related Links: ACMA Licensing application forms and fee schedule.
