March 2010 RMT & Tsunami Warning Test

ARCSTV successfully received and retransmitted the March RMT at 0949 local time, March 24, 2010.  This exercise also served as the annual statewide tsunami warning communications test.  The test in the recording presented here was viewed at the APBI offices in Anchorage using a 3.0 meter C-band dish and a Scientific Atlanta D9223 receiver. The recording was made using a VHS tape recorder with audio source taken from the left channel of audio output #1.

This recording positively demonstrates the successful execution of the drill and delivery of the test material.  Below the recording is the printout from the Sage ENDEC confidence decoder at the APBI offices, showing that the test signal as delivered by ARCSTV was properly distributed and relay-capable.  The ARCSTV signal is available to any person or organization in possession of a properly installed and functioning C-band satellite antenna and an MPEG-II DVB satellite receiver.

ARCSTV's primary mission is to serve the residents of bush Alaska through a network of over 200 low-power analog television transmitters, but ARCSTV is also used by commercial and non-commercial broadcasters around the state as a monitored source for their EAS facilities.

 Sit back, relax, and watch the pictures, now, as they fly through the air.

ARCSTV will participate in the upcoming test of the Tsunami Warning Communications System set for middle of Tsunami Awareness Week

Here's the info from NOAA's Alaska Region web page:

OFFICIALS TO CONDUCT TEST OF THE ALASKA TSUNAMI WARNING SYSTEM
NOAA's National Weather Service and Alaska's Division of Homeland Security and Emergency Management, in cooperation with local emergency management offices and the Alaska Broadcasters Association, will conduct a statewide test of the tsunami warning communications system on Wednesday, March 24 at 9:45 a.m.

The test is part of Tsunami Awareness Week, proclaimed by Gov. Sean Parnell as March 21 to 27. The week coincides with the anniversary of the Good Friday Earthquake - a devastating 9.2 magnitude earthquake that triggered deadly tsunamis in Alaska on Good Friday, March 27, 1964.

The communications test will involve NOAA Weather Radio All Hazards, the emergency alert system and other state and local communication links. Radio listeners should hear the familiar alerting tone followed by an audio message describing the test, similar to the routine monthly tests of the emergency alert system. Residents of some communities may hear sirens.

It is important to note that some television systems are programmed to scroll a standard message based upon the emergency code received. In some cases, the message may not contain the word 'TEST'. An audio message will say that it is a test, but if the volume is turned down or otherwise unheard, viewers may not realize the warning is a test.

The general public can participate in the test by monitoring NOAA Weather Radio All Hazards, commercial radio, cable TV or local television for the emergency alert system message. Local emergency management may use the test to help raise awareness of the tsunami hazard. If there is excessive seismic activity on March 24, the test will be canceled.

The public can provide feedback online at http://www.tsunami.gov/test. People monitoring the test in coastal areas who do not receive the test through commercial or weather radio should inform their local National Weather Service office.

ARCS, Digital Television, and The Future


You have probably heard a lot about Digital Television and the upcoming February deadline when “all TV must be digital”. Well, not exactly. Even after February 2009, ARCS will still be “Analog” and your current TV will work just the same way it does now. You won’t need to make any changes to keep watching because ARCS is a “low-power” television system that is not required by the FCC to convert to digital at this time.

The FCC has required some 1,700 full-power stations nationwide to meet this conversion deadline. However there are nearly 7,000 low-power transmitters across the USA, just like ARCS, which are not yet required to convert. Most of these transmitters serve viewers in rural communities.

ARCS probably will convert to digital in the next three to five years, so eventually you will need to do something. One thing you can do right now is check out the TV Converter Box Coupon Program. Created by Congress, this program allows households to get up to two coupons, each worth $40, for use in obtaining a box that will convert over-the-air digital television signals for viewing on an analog television set. Even though you won’t need a converter to watch ARCS in the near term, you can still get your coupons, use them to purchase converters at the reduced cost, and then keep them for future use. You can find out more at http://www.dtv2009.gov/ or by calling toll free, 888-388-2009.

Meanwhile we continue to work with volunteers across the state, in more than 230 communities, to repair and maintain the ARCS system.
