Please be aware that due to the breadth of this series of weather events, numerous emergency and public service nets are in session, especially on the 80, 40, and 20 meter bands. US licensees are reminded that Part 97.101 (c) always gives priority to stations providing emergency communications. All stations should be aware that in a large-scale natural disaster, immediate threats to life and property can happen quickly. In order for Amateur Radio to play an effective role in supporting humanitarian efforts, it is key that all licensees cooperate to minimize potential on-air problems.
Amateurs should also be aware that the primary users on the 60-meter channels are using those channels extensively. Amateur stations, as secondary users, must ensure that their communications are conducted in such a manner to ensure that Federal government stations, as primary users, can have immediate use of any 60-meter channel. Amateurs, please make sure you are leaving adequate breaks between transmissions to allow the primary stations to use the frequency. If a primary user does break into an amateur contact on the frequency, the amateurs involved should immediately cease their transmissions.
At this time, it is ARRL's understanding that only Amateur Radio Emergency or Amateur Radio Priority traffic is moving in and out of the affected areas. Amateur Radio Health and Welfare communications are being queued up for later delivery into the affected area, as the emergency and priority traffic eases.
In the aftermath of a natural disaster, it is human nature for persons outside of the affected area to seek information on their loved ones. Those wishing to send Health and Welfare queries are encouraged to use the American Red Cross's ''Safe and Well'' website to facilitate those contacts:
