|I'm a poor student and can't afford the deposit for a telephone line. Is there any kind of telephone or radio that I can use to communicate with other people? — AG, Tulsa, OK
Yes, you can use a radio to communicate with your friends, but they will also have to have radios. Amateur radio has been popular almost since the invention of radio and the most accessible version of this hobby, citizen band or CB radio, was extremely popular in the 60's and 70's. You can still buy CB radios and communicate with friends directly through the air, but the general interest in CB radio has waned in recent years. Unfortunately, you can't make your friend's radio ring to alert them to begin listening. You'll have to anticipate your "call." Also, there is no privacy on conventional radio—any nearby person with a similar radio can listen in.
