A Radio To Communicate...

In times of emergency or while you are out and about having a way to communicate can be handy. It may even save a life. Now, there are several types of radios; FRS, GMRS, MURS, Amateur, etc. Cell phones are every where, but maybe there is no coverage. Something has caused the local cell to be off the air? What to do now?

FRS & GMRS operate up in the 400 MHZ range of frequencies. Good for keeping in touch for everyone in a two to five mile radius. The user can set up privacy codes, but the transmission is not secure. The privacy codes just let the users "call" each other by setting a code up in each radio. Prevents unwanted contact in the band.

Trisquare TSX-300 and its variants are pretty cool radios that operate in the 900 MHZ range. Limited in distance, maybe on a good day a user can get a mile. But, that depends on the terrain. The best I could do is half a mile. You may ask what good these radios are? Well, they use spread spectrum frequency hopping, texting capability radio to radio. Each radio has a specific address. This means users can communicate directly without people listening in. Or use the group frequency and talk to all radios. More frequency codes then you can imagine.This results in a very secure means of communications in your AO base camp and vicinity. Some users have complained that they cannot sync more than three radios. At the moment I have two of these with plans to get more to test out. Amazon has these radios at a reasonable price for two.

Lastly, the one radio I found to be a bargain; Baofeng UV-5R. This little hand-held radio is excellent for the money. Less than 60$ at Amazon. Has more features than you can shake a stick at. Single LED flash light, FM broadcast band reception, transmits high and low of the 144 and 400 MHZ ham bands. Can be programmed by a USB cable attached to your PC. Takes a little bit of time to get it programmed, but I found some useful Youtube videos to help out. Once again the price is great for a radio that will do as much as more expensive radios.

Give some thought to how your family, friends, and neighbors will communicate during an emergency. Develop a plan and acquire the equipment you need to keep everyone safe and in touch.

Enjoy
