English:
A collection of
walkie-talkies
, handheld portable
two-way radios
for recreational use. From left:
Commercial and emergency services walkie-talkies may be similar in size to the amateur units shown here, but generally have much better battery life, more rugged construction, and simpler controls, often restricting operation to only one or a few pre-programmed channels. In addition, many have ruggedizing features such as waterproofing (especially for outdoors and marine use) and intrinsically safe design for use in fire-prone industrial environments. The two older walkie-talkies on the right use only discrete transistors; all the more recent ones shown here use microprocessors and integrated circuits for most of their functions. |
