20 Meter Band SEANET
The South East Asia Amateur Radio Network (SEANET) was established in 1964 on 20m (14.320 MHz plus or minus QRM). The objective of this Net is to promote international understanding and fellowship among hams and to relay emergency, medical, urgent or priority traffic. This on-the-air meeting which has taken place without fail daily at 1200 UTC has strengthened unity and co-operation among Hams around the world, especially those within the region. The net also provides Hams a facility for testing their equipment and propagation conditions on the 20m band.
