Amateur Radio 630m Band in Australia

As of 1st January 2013, Australian Advanced amateur licensees can operate in the new wavelength band (630 metres) on a secondary basis in the segment 472 kHz to 479 kHz - refer to Radiocommunications Licence Conditions (Amateur Licence) Amendment Determination 2012 (No. 1) for details.

This secondary allocation is conditional on the Amateur Radio Service not interfering with a primary service, viz. aeronautical navigation Non Directional Beacons (NDBs) operating within and adjacent to the 630 m band.  Protection for these NDBs from transmitters operating in the Amateur Radio Service is provided via two exclusion zones; viz. Australian territory lying in the areas defined as follows:
This web page provides a map showing the exclusion zones, including the overall exclusion zone; and a list of coordinates (latitude and longitude) which are used to define the overall exclusion zone on the map.

Please note that this is provided for information only - readers are reminded that the LCD Amendment Determination is the defining reference, and not this web page!
