NVIS for EMCOMM and Survival Communications.

Not clear on the concept. If you or someone you know has an HF station with a goal of DX communications in disaster situations, I have a question: What are you really trying to do? What is the need for very long distance communications in a SHTF scenario? Save for... Read more Β»

FRS3 For Colorado Backcountry

27 June 2024 at 14:10

The Colorado Search and Rescue Association is promoting FRS (Family Radio Service) Channel 3 as β€œthe default during backcountry search and rescue (backcountry SAR) emergencies.” FRS channel 3 is the same as GMRS (General Mobile Radio Service) channel 3. There is more GMRS info here. To keep things simple, no CTCSS (β€œprivacy code”) is used…carrier squelch only.Β  See the CSAR Continue reading FRS3 For Colorado Backcountryβ†’

FRS3 For Colorado Backcountry

By: Bob K0NR

The Colorado Search and Rescue Association is promoting FRS (Family Radio Service) Channel 3 as β€œthe default during backcountry search and rescue (backcountry SAR) emergencies.” FRS channel 3 is the same as GMRS (General Mobile Radio Service) channel 3. There is more GMRS info here. To keep things simple, no CTCSS (β€œprivacy code”) is used…carrier squelch only.Β  See the CSAR announcement here: FRS Radio Use for Backcountry.

For backcountry exploring, it is important to emphasize self-sufficiency and to avoid reliance on electronic gizmos that may fail. Avoiding an emergency situation is way better than having a device to call for help, which may be many hours away. See this article for a discussion of The Ten Essentials for Hiking.

Still, the FRS3 concept has merit. Many backcountry hikers already carry FRS or GMRS radios, so designating a preferred channel makes sense. My read on this is that randomly calling for help on FRS3 will not be very effective due to the limited range of FRS radios. However, it does not hurt to try. More likely, FRS3 can be used for local comms once Search and Rescue crews have been deployed and are within a few miles of the party in distress.

Ham radio operators may want to carry a handheld transceiver capable of transmitting on 462.6125 MHz. For emergency use only, of course.

2024 ARRL Field Day at Windham Summerfest

By: WS1SM
5 June 2024 at 18:52

WINDHAM, ME – The Wireless Society of Southern Maine will participate in the American Radio Relay League’s Summer Field Day activities during Windham’s Summerfest event on June 22nd. Once Summerfest activities end on Saturday evening, ham radio operations will continue through the night and end on Sunday at 2 pm. The public is welcome to visit each operating station to learn more about ham radio.

ARRL Field Day is the single most popular on-the-air event held annually in the US and Canada. On the fourth weekend of June of each year, thousands of radio amateurs gather with their clubs, groups or simply with friends to operate from remote locations.

Field Day is a picnic, a campout, practice for emergencies, an informal contest, and, most of all, FUN!

It is a time when many aspects of Amateur Radio come together to highlight our many roles. While some will treat it as a contest, other groups use the opportunity to practice their emergency response capabilities. It is an excellent opportunity to demonstrate Amateur Radio to the organizations that Amateur Radio might serve in an emergency, as well as the general public. For many clubs, ARRL Field Day is one of the highlights of their annual calendar.

The contest is simply to contact as many other stations as possible and learn to operate our radio gear in abnormal situations and less-than-optimal conditions.

Ham operators use these same skills when they help with events such as marathons and bike-a-thons; fund-raisers such as walk-a-thons; celebrations such as parades; and exhibits at fairs, malls, and museums β€” these are all large, preplanned, non-emergency activities.

But despite the development of very complex, modern communications systems β€” or maybe because they ARE so complex β€” ham radio has been called into action repeatedly to provide communications in crises when it matters. Amateur Radio people (also called β€œhams”) are well known for our communications support in real disasters and post-disasters.

What is Amateur Radio?

Often called β€œham radio,” the Amateur Radio Service has been around for a century. In that time, it’s grown into a worldwide community of licensed operators using the airwaves with every conceivable means of communications technology. Its people range in age from youngsters to grandparents. Even rocket scientists and a rock star or two are in the ham ranks. Most, however, are just normal folks like you and me who enjoy learning and being able to transmit voice, data, and pictures through the air to unusual places, both near and far, without depending on commercial systems.

The Amateur Radio frequencies are the last remaining place in the usable radio spectrum where you as an individual can develop and experiment with wireless communications. Hams not only can make and modify their equipment but can create whole new ways to do things.

Look for them on the athletic field next to the Windham Primary School. They will have signs throughout the facility to point to the location. Actual ham radio operations will begin on Saturday @ 2 pm and end on Sunday @ 2 pm.

Hope to see you there!

Data Modes: Game Changer or Gimmick?

25 April 2024 at 02:14

Time + technology= options. Ham radio has a lot more options than it did years ago. Back in the day your choices were phone or CW and that was about it. In the 1970s/1980s slow scan TV and early data such as RTTY came about, but they were niche modes... Read more Β»

Batteries: Your Weakest Link.

It cannot be avoided… Batteries are arguably the weakest link in the off grid radio chain. Solar panels, controllers, connecting cables, and almost everything else can last years, even decades. But batteries are a consumable product and no matter how good yours are, it’s almost certain they will not last... Read more Β»
