Personal Locator Beacons

Personal locator beacons, or PLBs, are an important piece of safety equipment for anyone in the outdoors. They can signal a distress beacon to alert search and rescue teams if you become lost or injured during a hike or any other type of outdoor activity.

Today there are several different types of personal locator beacons available on the market, each with its own advantages and disadvantages. One popular brand is ACR Electronics’ ResQLink+, which features a 10-year battery life, weighs just 4.6 ounces (130 grams), and is waterproof up to 16 feet (5 meters). It also has two significant safety features: GPS location technology for pinpoint accuracy, and “Man Overboard” mode designed specifically for boaters.

Another popular brand is the Garmin inReach, which features a two-way satellite communication system and access to its own SOS alert services worldwide. The inReach also has an emergency response center that can provide help from specialists with experience coordinating rescues in remote areas. However, it does not have a Man Overboard mode like the ResQLink+.

For those who want even more reliable communication options when out in the wilderness, satellite phones are another option. A satellite phone provides a direct connection to the global cellular network and allows users to place calls as well as send and receive text messages anywhere on Earth, provided they have line of sight with at least one geostationary satellite. They are an ideal tool for adventurers who may not have access to any other form of communication, and they can be used in conjunction with a personal locator beacon for added security.

No matter which type of device you choose, it is important to remember that a personal locator beacon or satellite phone is only as useful as the person using it. It is always wise to practice safety protocols when out in the wilderness, such as letting others know your plans, carrying appropriate supplies, and taking necessary precautions against injury or getting lost. With the right equipment and knowledge, you can help ensure your own survival in any outdoor situation.

Whether you are a solo adventurer or part of a team, having the right personal locator beacon can be essential for survival in any outdoor situation. The devices come in many shapes and sizes, with varying features and capabilities. Make sure to do your research before investing in one so that you choose the device best suited to your needs. With the proper preparation and knowledge, you will be able to enjoy Mother Nature’s beauty while keeping yourself safe at all times.

Is Amateur Radio Dead?

Amateur radio, also known as ham radio, is a popular hobby amongst technically-minded people who enjoy communicating with others and learning about electronics. Despite its popularity in the past, the number of amateur radio enthusiasts has been declining in recent years. There are several reasons for this decline.

First, modern technology has made amateur radio less relevant. Many radio-related activities, such as broadcasting and distance communication, can now be done with cell phones or the internet. Amateur radio operators need to have a license in order to use certain frequencies, so most people opt for other simpler options like smartphones instead.

Second, amateur radio requires a large investment of time and money in order to setup and maintain the necessary equipment. Amateur radio operators need to have an antenna, transceiver, power supply, and other components. This can be expensive for hobbyists who may not have much money to spare.

Finally, amateur radio is seen as being old-fashioned by many people today. The technology used in amateur radio has remained largely unchanged since its introduction, while other forms of communication have advanced significantly. People tend to prefer the newer, more modern options such as the internet or smartphones instead of using outdated methods like amateur radio.

Despite this, there are still many avid amateur radio enthusiasts who use the technology on a regular basis. Amateur radio is a great way to stay connected to other people around the world and can be a lot of fun for those who are interested in it. However, it is clear to see why amateur radio has become much less popular than it once was. The outdated technology, expensive equipment, and lack of modern features have all contributed to its decline in recent years. With a focus on modern technologies, amateur radio has become a thing of the past.

Amateur radio was once an invaluable source of communication in emergency situations, however with the advancements in technology and internet access even rural areas now have access to much more reliable methods of communication. Smartphones provide a wealth of information at anyone’s fingertips and are much easier to use than bulky, outdated radios.

The cost of the equipment is also a factor in why amateur radio has lost its popularity. Amateur radio requires multiple pieces of expensive hardware and antennas that need frequent maintenance and can be costly to repair. This makes it too expensive for many people who may otherwise be interested in using this type of communication technology.

The complexity of using amateur radio is also a major factor in its decline. It requires a lot of technical knowledge and skill to properly use, which can be intimidating for beginners. Additionally, the license needed to operate a transmitter on any public frequency is difficult to obtain and time consuming to understand. This has caused many people to simply give up on the idea of getting involved in amateur radio.

The internet has also taken away many of the reasons to use amateur radio. The internet is much easier to use than an amateur radio and it enables people to easily communicate with each other from anywhere in the world, without having to worry about technical knowledge or expensive hardware.

Finally, the cost of getting involved in amateur radio has become too prohibitive for many people. The hardware and licenses required to participate are expensive, and the costs can quickly add up.

Overall, amateur radio is no longer as popular as it once was due to a number of factors like complexity of use, availability of better alternatives such as the internet, and the cost associated with it. Unfortunately, this means that fewer people are able to experience the joys of amateur radio. However, there is still a passionate community around the world that continues to practice amateur radio and keep it alive.

For those looking to get involved in amateur radio today, they have access to online learning resources, as well as clubs and organizations that help guide newcomers. As technology advances, the cost of participation has become more affordable. With a little bit of effort and dedication, amateur radio can still be an enjoyable hobby for many people. There is still something special about a direct line of communication with another person, without the need for any infrastructure. In a survival situation, ham radio can still be a critical asset.

General Mobile Radio Service (GMRS)

GMRS is a great way to stay in touch with family members during an emergency or while outside of cellphone reception range. It operates on a set number of frequencies, requires a license available online, and maxes out at 50 watts of power. Typical range is between 5 & 25 miles. More information is available here: FCC GMRS Information.

FRS Channels also used by GMRS

The reasons to use FRS channels with a GMRS license is either that the GMRS channels are too crowded (unlikely), your communicating with someone outside your family who doesn’t hold a GMRS license, or you’re using handheld units and are in close enough proximity to use lower power settings. You always only want to use enough power to make clear contact. This is partly to be courteous to other radio users, and also to limit power consumption and wear on your radio gear. Just because your mobile radio is capable of outputting 7 watts of power doesn’t mean you’ll set it to 7 watts and forget it. Try lower outputs and see if you can still communicate. This is particularly true while camping and hiking while the other person is just out of site.

Communication

Imagine a scenario where you’re driving home from work and there’s a traffic jam. You don’t think much of it at first until you notice panic in the faces of other motorists. Something has happened and it’s bad. You reach for your cellphone to call your wife and receive the message “We’re sorry, your call cannot be completed at this time.” The cellphone network is jammed because too many people are trying to use the network at one time. What do you do now?

We’ve become so dependent on cellphone technology that it’s hard to imagine our phones just not working, but it’s happened before. In times of natural disasters the cellphone networks have often collapsed. Even large events like football games have overworked networks to the point of collapse. They’re simply not designed for everyone to be on them at once. For this reason there has been a push towards getting people to send text messages instead of voice calls in emergency situations because it frees up the network. Unfortunately it’s not so easy for crowds to think so rationally during an emergency, and I too would try to call my family, not text. So what are the other options besides a cellphone? It’s simple, direct radio communication.

CB, amateur radio, and GMRS, are all systems that can keep you in touch with your family should SHTF. The only one that requires no license is Citizen Band radio. GMRS requires that you pay a fee to the FCC for a license which is good for 10 years and includes your family members at no additional costs. Amateur radio will require that you pass a written exam to become a Technician and you can then progress to the General license after another exam for bands that are able to communicate around the world. So which is best for you?

I should start out by letting you know that in an emergency situation all bands are fair game; however, you should pick a band that allows you to legally practice and become proficient. Your family should know the frequencies you will be using and you should designate 1 frequency where you’ll be able to find each other, as well as a backup frequency.

As a licensed amateur radio operator I’ve been partial to ham radio. It can be fun for the whole family and as a technician you have access to the 2 meter band as well as 76cm, plus all of the local repeaters across the country to really boost your coverage area. Some limited shortwave communication is also possible with the technician class but to really open up the shortwave bands you’d want the General license. If a test is not something you want to undertake then your next best thing would be to pay the FCC fee and acquire a GMRS license. You’re limited to 50 watts of power but that’s still much better than the 4 watts of power from CB radios, and GMRS radios have access to GMRS repeaters as well. With a little planning you should be able to communicate with your family directly if within range, or through a GMRS repeater.

Any dual-band amateur radio should work on GMRS as long as you don’t go over the 50W GMRS limit. Handheld units are also great for hiking, but typically max out at between 5 and 7 watts of power. For the full 50W you’d want a vehicle mounted system. Keep in mind that if you have a vehicle mounted system and your family has a handheld you could end up in a situation where they hear you but you cannot hear them. You could setup a home base station with a large roof-mounted antenna for even better reception. The sky’s the limit when it comes to radio communication. No pun intended.
