Hmmm.. From the last time I looked at HAMs, they all required power or battery.. If there is no electricity for a week or a month, will your HAM still work?

I pay $5 a month for my landline, no long distance, nothing, just the dial tone.. I only use it for toll free calls when I need to talk to my bank, or any other institution that requires me to "authenticate" myself. For all other calls, I use my VoIP or my cellular.
