Walkie-talkies using the Raiders
Walkie-talkies using the Raiders
Walkie-talkies for communication between members of outdoor activities, there is no signal in places where mobile phones are very effective.
Radio power and communication distance:
Civilian radio power is generally 0.5w, communication distance is 3 kilometers under ideal conditions, obstructions in a building environment that will reduce the actual effective communication distance. Such a small size and light weight radio features, for a small team within the Communications and outdoor activities without any communications costs, save money.
Professional radio power is generally 2w, communication distance 10 km, the urban area 3 km;
Are theoretically of course, but once in the Bogda stronghold, with moto of a police radio, actually clearly hear the foot of the dialogue: "Get them to the Bureau of go," so I was shocked into a cold sweat .
Typical walkie-talkie models: Motorola, there t6200c, Mickey type / princess type, t5428, t5308 and other models, all civil 0.5w, and also North Peak, General Star, julier, Kenwood and other models. But most of the fire is Motorola's several civilian aircraft, small, inexpensive, and civilian bands, without the formalities. 6200c which is consistent with the public SRRC opening band.
Radio price:
Motorola in several price around 300-500.
Radio frequency: 10-20 generally talk radio channels, as long as the same channel can talk to each other, regardless of how many. If a channel is not clear or there is interference, you can talk well, to switch to other channels. Do not forget to discuss our amazing good, if a change, and one did not change, it was blind.
SRRC frequency 409mhz open to the public within the 20 frequencies, the Motorola 6200c is this band, so you can open the phone shop to sell. There are many radio and using foreign frs (family radio) standard, for example I bought BF5118, operating frequency is 450mhz and 470mhz in the vicinity.
Although frs frequency does not meet national norms, but because only 0.5w, no one bought the pipe, but the 6200c and Motorola can not be communication, so the time in outdoor activities, radio and more, and first see if you can with each other pass.
Remember, push to talk is a single worker (unlike phone is duplex), if you keep button has been accounted for channel words, other people say does not become. So popular is text messaging walkie-talkie-style dialogue, you are one, I am one.
Walkie-talkie batteries:
Professional multifunctional rechargeable battery, the same as mobile phones, nickel metal hydride or lithium; civil aircraft with more ordinary batteries, aa or aaa, usually with a 3-4, you can also use rechargeable aa or aaa.
According to the outdoor experience, battery life is generally a two day, which is 20 hours or so. I often see people with a walkie-talkie to the camp to yell, telling everyone to turn off the radio. Best with rechargeable batteries, an investment more slowly on the cost-effective, or else an event must take into account four South-fu.
The use of walkie-talkie: general outdoor activities, a dozen individuals, with 2-3 radio enough, a captain, a Pathfinder, a guard, more Fandao chaos. Radio more than one, into a microphone and karaoke ok, and let the rogue take on a number of songs, was even worse.
Some people think that radio is not used in the outdoors, I do not agree. Walkie-talkie of the most important role is to enhance the confidence of the team leader and to know whether the good road to go ahead, that opened after the team members, you can master the rhythm of the march for the team's happiness is very important.
Radio should be used in smart, have to master a number of radio language, taking into account the work of radio simplex method, while the signal field is not very stable, it should be possible to simplify complex statements, but to use Mandarin. Hou Baolin comic dialogue heard it? According to Mr. Hou's theory, the radio should try to control people in Henan, Shandong, or hands, do not fall into the hands of Peking Man, one wordy, and second dialect too, there are Cantonese does not work, days are not afraid , in fear, afraid Cantonese Putonghua. Zan Xinjiang this place quite a mixed bag, which the people have to be cautious.
In addition, the finished one end, said an "over", would seem very knowledgeable.
Another very important point, when people use walkie-talkie, is facing the rear of radio palm, I used to as well. Look after people take law professionals, just turn the panel against the palm. I guess this has two advantages: First, if missed fall, radio's front panel is not easy to damage, and second, look more professional, and will not someone to see you say: "You, the new donkey bar
