Last week when they toned out their weekly Wednesday test, the automated announcement said 'This NOAA transmitter is out of service', etc. About 30 minutes later they figured out their error and aired the expected test. I kept wondering how a transmitter that is out of service was transmitting that information. I should call them on my phone the next time my phone is out of service.
They frequently seem to have trouble figuring out how to make the test procedure work. Doesn't inspire confidence in their abilities.
