Do those use a frequency band that's suitable for cellphones to monitor (antenna size, power, etc)? Because your best chance of getting my attention in an emergency is to make my phone start shrieking.
NOAA Weather Radio frequencies are in the 162 MHz band. I have no idea how well a cell-phone could pick that up, but even if they could, it's going to be a power draw. Also, there are 7 different channels, and the phone would have to know which channel to tune for the local area. For phones, it is much more practical to use the (already provided) notifications from the cell network (which you can mostly opt out of as well). -- Chris Adams <cma () cmadams net>
