Two-Way Radio Links
A cell phone is the obvious alternative to a two-way radio. One downside is the cost of airtime, but many plans include free connections to other subscribers or unlimited minutes. In addition, Verizon and Sprint Nextel currently offer "push-to-talk" phones that can also be used as walkie- talkies. But cell phones are at a disadvantage in wilderness areas where there will be no reception or spotty reception.
The Federal Communications Commission (FCC) has information about two-way radios and licensing requirements.
The FCC also has a page explaining GMRS.
The Two Way Radio Directory is an extensive resource for all things relating to two-way radios. The site offers forums and links to other resources including dealers, distributors and emerging technologies.
