In this frequency band, stations in the amateur service shall not cause harmful interference to, or claim protection from, stations of the aeronautical radionavigation service.
302:, the 505–515 kHz band was allocated to amateur radio temporarily, "pending an international frequency allocation", on 1 March 2010. Amateur use is on a non-interference basis, and transmissions are limited to 25 watts EIRP, with a bandwidth not exceeding 200 Hz. Now that an international frequency allocation has been made by the
99:, a 15 kHz allocation to the amateur radio service was considered on a secondary use basis. The frequencies studied were between 415 kHz and 526.5 kHz. The result was that 472–479 kHz was identified as agreeable for all three ITU Regions, except for some countries such as Russia, China, and some Arab states.

WRC-12 re-allocated the original 500 kHz frequency back to exclusive maritime mobile use for new navigation systems. On 14 February 2012, the delegates at WRC-12 formally approved allocating 472–479 kHz to the amateur radio service; however, this new allocation will not take effect

The new WRC-12 allocation did not take formal effect until 1 January 2013. However, several countries had already allocated the WRC-12 band to amateurs domestically. Previously, several other countries authorized temporary allocations or experimental operations on nearby frequencies.

277:, amateurs were allocated 501–504 kHz on a secondary basis on 15 January 2008. Only CW may be used with a maximum ERP of 5 W. On 14 August 2013, an additional allocation for 472–479 kHz has been added allowing all modes of transmission.
262:, amateurs have an allocation from 472–479 kHz. Restriction in this is that no contests are allowed, and only the modes A1A, F1A, G1A, and J2A are allowed. The allocation is secondary, and a maximum power rating of 100 watts PEP is allowed.

and subsequently implemented in New
Zealand, this temporary band is being phased out. A transition period of one year was given for amateurs to move to the new allocation. Use of this band will not be permitted after 31 December 2013.
150:, on 14 August 2013, a new allocation of 472–479 kHz has been added to the existing allocation of 501–504 kHz for ham radio operators holding a HAREC-class license. The maximum EIRP is 5 watts. All modes are permitted.

until it is entered into the ITU's Radio
Regulations. Following that, individual regulatory authorities need to implement the change nationally in order to make the allocation available to radio amateurs under their jurisdiction.
284:, the band 493–510 kHz was allocated to radio amateurs on 6 November 2009. Only radiotelegraphy is permitted. After WRC-12, this allocation was replaced with an allocation of 472–479 kHz.
