When disastar came, how can you ask for Help?
Maybe you’ll say, just carry my phone! However, when we reach a remote place, your mobile phone has no signal, or a place with good signal, but where nearby mobile phone base station is damaged (such as an earthquake). it may also let us lose contact with the outside. We can’t make phone’s signal go farther, but Amateur Radio Emergency Communication can do so. There will be always Emergency Communication channels all over the world, and there are radio amateurs on the air from the world. As long as your SOS signal is received, the chance of your being rescued will be much greater.
Of course, it’s unexpected. But if it does happen, we have to be faced. our life is important, think of those we love and those who love us. And maybe a group of people would be rescued because you knew ”Amateur Radio Emergency Communication“—whether you transmited or received the signal. So just prepare for it in advance!
When an emergency disastar occurs, it is often accompanied by the destruction of power supply, public telecommunications, road traffic and other facilities, temporary interruption of contact with the outside etc. At this time, the primary task of Amateur Radio Emergency Communication is to quickly set up a radio station ,to call for help.
Seven steps to use your Amateur Radio:
1. Install the battery and confirm that it is locked with the radio body
2. Check the antenna to make sure the contact is good
3. Start to turn on
4. To set or check the same frequency/channel, your amateur radio and other walkie talkies in the same group
5. Set the transmit power: (First check the battery is fully charged. For example, when the transmit button PTT is pressed, the transmit indicator (usually red) flashes. Using high power to transmit will consumer more power immediately. Or try to use lower power to maintain a longer talk time.)
6. Adjust the squelch SQL to a right value where there is just no extra noise (if the squelch SQL knob is adjusted too higher, weaker signals will be missed and the call distance will be shortened.)
7. Press PTT to transmit, try connecting with teammate in a group, adjust the volume, and confirm that the handheld transceiver is normal, and start to talk.
Lastly but most importantly, For Amateur Radio Emergency Communication, “SOS call” and “SOS reply” are the highest level of signals, which must be heard/received by any amateur radio stations. whether contacting or not , you should interrupt the transmission immediately and unconditionally, and turn to the listen/receive mode and give necessary assistance or help.
Note: 145.000MHz and 433.000MHz are international emergency frequencies
