Now in its fourth year, the World Autism Awareness Week special event will again carry the message that "it's OK to be different." It's a theme uniting amateurs across oceans, with callsigns that include W2A here in the US and others in participating nations such as Italy, South Africa, Russia, New Zealand, Australia, Argentina, Israel and West Malaysia.

This weeklong special event begins on Wednesday the 1st of April. It has gained momentum as it brings advocacy on the air for those with autism spectrum disorder - a developmental disorder seen among people of all races and nationalities.

More details about the event and its callsigns - as well as useful information about autism spectrum disorder - can be found on the QRZ.com page of W2A.
