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) 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 Link 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.
