Follow-up on communications

As a follow-up to my earlier musing on communication technologies, I did pen recently a document summarizing the various licensed and unlicensed two-way technologies that are available to people here in the United States and Canada. Here is the current version of it:

(Should a new numbered version get created of this document, you will be able to find the update by checking at this webpage: http://home.mchsi.com/~anderson.kevin/)

Two-way radio will only be a stop-gap measure, as eventually we won't have the parts or electricity to keep it going. But between now and then some people will want to have it available.
