On the afternoon of Tuesday, February 7 (Geneva time), Committee 4 of the 2012 World Radiocommunication Conference (WRC-12) approved Option 1 to satisfy Agenda Item 1.23, with minor editorial amendments to the text received from Working Group 4C.

Option 1 calls for a worldwide secondary allocation to the Amateur Service at 472 – 479 kHz, with a power limit of 1 W EIRP, with a provision for administrations to permit up to 5 W EIRP for stations located more than 800 km from certain countries that wish to protect their aeronautical radionavigation service (non-directional beacons) from any possible interference. Option 2 was NOC (no change to the current rules).
