| Keywords: Recreational Walkie Talkies.jpg A collection of walkie-talkies handheld portable two-way radios for recreational use From left Motorola FRS radio purchased in 2002 which operates on the Family Radio Service band Motorola dual band walkie-talkie purchased in 2004 which can operate on either the FRS or the General Mobile Radio Service GMRS channels On both these radios the antenna is permanently attached as required by FCC regulations for FRS gear Early 1980s amateur radio transceiver for the 2 meter 144 MHz band complete with external speaker-mike and DTMF keypad for remote repeater control and phone patch operation Smaller amateur transciever for the 2 meter 144 MHz and 70 cm 428 MHz bands Although similar in size to the smaller FRS units it is much more versatile has a higher transmit power and can transmit on any of several hundred frequencies in two Amateur radio bands A 1960s vintage toy walkie-talkie operating in the 27 MHz Citizens' Band; its 900 mm 36 inch whip antenna is partly extended This unit has a superheterodyne receiver and 10 transistors A mid-1980's toy walkie-talkie operating at very low power in the 49 MHz band with a Morse code key and the Morse code printed on the case This unit has only 4 transistors and no volume control or squelch In addition rather than the telescoping whip antenna common on earlier models this unit has a rubber duck antenna which is thought to be more robust and less dangerous to the user if broken and has replaced telescoping antennas in virtually all children's two-way radio units 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 en wikipedia Premeditated Chaos CommonsHelper 2005-04-21 Wtshymanski wikipedia en Wtshymanski Original upload log page en wikipedia Recreational_Walkie_Talkies jpg 2005-04-21 04 01 Wtshymanski 640×480× 107183 bytes <nowiki> pd Recreational walkie-talkies From the left two different models of FRS radios by Motorola Third from the left an early 1980's amateur radio radio for the 2 metre band complete with external speaker-mike and DTMF keypad for remote</nowiki> Walkie-talkie | ||||
