Analog walkie-talkie is an analog walkie-talkie (also known as traditional walkie-talkie) designed with analog communication technology, which is to modulate the stored signal to the transmission frequency of the walkie-talkie.
The advantage of the card walkie-talkie is that it breaks through the limitation of distance, unlimited distance national intercom, as long as there is a network of places can intercom. Analog machines can generally only reach a distance of 1-3km due to environmental limitations, and the same is true for digital walkie-talkies.
As an electronic communication device, the walkie-talkie also has a certain amount of radiation in the process of use. Unlike electronic devices that are used for a long time, such as mobile phones and tablets, analog walkie-talkie calls are intermittent and only generate high power when transmitting. Therefore, compared to mobile phones, the radiation of walkie-talkies is almost negligible. The card walkie-talkie is constantly searching for signals and transmitting beacons as long as it is turned on, and there is always radiation.
In addition, when we use the walkie-talkie, as long as we master the correct use method, we can also further reduce the radiation of the walkie-talkie. For example, when using the walkie-talkie to press PTT to talk, when the transmitter is transmitting, you can put the walkie-talkie in a vertical position and keep the distance between the microphone and the mouth about 25-5 cm, walkie-talkie at least 2 miles away from the head or body5 cm.
In fact, in addition to the electromagnetic radiation produced by electronic devices such as walkie-talkies, mobile phones, and tablets in daily life, the sun is the most powerful "radiator", and the radiation intensity is much higher than that of electronic products. Therefore, as long as it is a walkie-talkie of a regular manufacturer, the radiation value is within the range specified by the state, you can use it with confidence, and you don't have to worry about radiation problems!
