I am having trouble finding the right emergency weather radio. Shortwave..NOAA..CRANK ...SOLAR POWER?

We Answered:

NOAA All Hazard Radio, the new name for NOAA Weather Radio, is designed for local area warnings only. Therefore, a shortwave frequency is not used.

There are two main reasons for this:

1. Warnings are best handled by the local NOAA National Weather Service office which is responsible for most local warnings, advisories, and forecast. This lower power broadcast will make it less likely to interfere with another distanced NOAA weather radio station that is broadcasting at the same frequency for their local area.

2. When a warning is issued through the radio, a special code is sent out to activate only the area that matches this frequency code. Because there are a limited combination of codes it can use and a limited distance this code can be heard, the low power NOAA broacast same code can be reused again.

Since a shortwave radio broadcast frequency can be heard well passed the distance of the local office area of responsibility. The short wave radio frequency range is not really suited for this kind of broadcast needs.

whats the best hand crank/solar power emergency radio with a big light available at a good price ?

We Answered:

Real cheap at any Wal*Mart, Walgreens, Home Depot or Lowe's. Also Radio Shack or eBay search for "crank radio" or the brand name "FreePlay" among others.

I'm in So. Fla. and keep a couple around for hurricane outages.

Originally developed by a good samaritan engineer for poor people in Africa who are without electricity and cannot afford batteries.
