I should add that if you use a smartphone, there is a free app from the ARRL for repeaters. Go to your Play Store and search on ARRL Repeater Directory. Be advised that you can listen but it is a federal offense to transmit or interfere on ameteur frequencies without a license. Hams are self regulating and will find you and prosecute you. We actually train to locate hidden transmitters. We call it a foxhunt.
Thanks. Would hand held ham radios such as Baofeng UV5R be useful when SHTF?
