HSMM-MESH Valley Hub Sites Testing!

Email regarding HSMM-MESH from David Bauman, KF7MCF, sent on October 30, 2013


Two Sites in Test Mode!

SLCC (Salt Lake Community College Hub Site)

The above photos show the SLCC Valley Hub Site.  It is composed of a High Power 2.4 Ghz Ubiquiti Bullet attached to a 15 dbi Commercial Omni Antenna (spec sheets attached).  The funny looking thing I am pointing at is a plastic pop bottle that is temporarily protecting the POE unit from the elements.  (Grant has replaced that with a weather proof box.)

This site is on top of a four story building at the Salt Lake Community College Campus.  It is running as an access point with regular Wi-Fi on Channel One with over 20 watts ERP output. With a little luck, the right equipment (and clear Radio Line of Sight) you should see it within about 5 miles, and you may see it out as far as 10 miles with the right equipment, skills, and circumstances.



Below is a view shed or rough idea of where the signal will hit out to about 5 miles.  The bite out of the circle at the bottom is because of elevation difference - Might be a coverage area also with a good antenna and a good Ham.

Ensign Peak Hub Site Testing also!

It is composed of a Linksys WRT54 router running HSMM-MESH 4.3 into a Renasis 1 watt Bi-directional Amplifier, and then Into a 17 dbi gain 90 degree Sector antenna with a bit of a down tilt (about 4-5  degrees)  


Below is a plot showing the Possible coverage area out to 10 miles.  If you are about half that distance, you have a good chance of connecting, with The right hardware, Clear Radio Line of Sight, and a bit of skill.  Remember, the signal does not hit the ground for about The first mile because of the elevation of Ensign Peak, and the 7.5 degree vertical beam out of the antenna.  This HSMM-MESH site is on Ch 1.  Because of the different operating Modes, the two Hub sites will not connect at the present.   Later that Will be resolved.  The Ensign Peak and SLCC sites are about 10 miles apart.  Credit for this site goes Ed Sim (N7RTA) and some of the guys from L3 group.  Nicely done!

The view below shows the possible combined coverage of Ensign and the SLCC Valley Hub Sites.  The other possible Future Valley Hub Sites shown  with distance from The SLCC Valley Hub are:  Church Headquarters (7 miles), Welfare Square (6 miles), Magna Bishop’s Storehouse (7 miles), and The Sandy Bishop’s Storehouse (6 miles), New IHC Med Center 2 miles, Storehouse Distribution Center 7 miles.
(About 10 miles From the SLCC  Hub Site to Ensign Peak.)

The View Shed picture below shows Possible future valley coverage from all proposed Valley Hub Sites

We are making progress, it is slow, but someday…

Thanks for all your help!  Anyone that can help us get other proposed sites up, or that just want to participate, just let us know.  Meetings are held Saturdays at 9 AM at the Magna Utah Bishop’s Storehouse ERC Com Center on 2nd floor. You are welcome to come and join with us, and have a donut!

Unlicensed Cheap Chinese Radios Can Cause Trouble

I found a really good posting from David Coursey, N5FDL's blog...here is a teaser...

"Got a call the other day from a local man who said he’d paid something in the $80 range to purchase a pair of radios from Amazon. “I bought them to use when I go out hunting,” he told me.

You may already see where this is headed. He’s purchased two “Cheap Chinese” talkies in hopes of using them for emergency backup and routine communications while hunting in the Sierras. He wanted to know if, perhaps, he needed a license and what would happen if he used them without a license.

“Do it often enough and we will find you,” I hold him. “After that, we will turn you in to the FCC. You can expect a letter from a Mrs. Smith and if you don’t comply, the fine is $10,000. You should probably send the radios back before they get you into trouble.”

I went on the explain that a license wasn't hard to get, but everyone who would use the radios would need one."

Communication in Colorado Flooding Response

Past news from the ARRL on the Colorado ARES response:

Amateur Radio Provides Critical Communication in Colorado

Flooding Response

Photo from businessinsider.com

More than five dozen Amateur Radio Emergency Service (ARES) volunteers have deployed in and around
flood-stricken counties of Colorado, providing critical communication for Red Cross shelters and state and local emergency operation centers. Recent heavy rains have caused veritable mountainside tsunamis that have caused rivers and streams to overflow their banks, ravaged roads and property and displaced an undetermined number of residents. At least three people are known to have died. ARRL Colorado Section Manager Jack Ciaccia, WM0G, says that with power cut off to affected communities and many cell telephone towers along the Big Thompson River toppled by the flooding, ham radio is providing medical and health-and-welfare traffic between evacuation centers and the EOCs.

"Every EOC is being staffed by ARES people," Ciaccia told ARRL. "Almost every evacuation center has an ARES communicator, doing either voice or packet communications between EOCs and shelters."

The isolated towns of Estes Park, Lyons, and Jamestown were or still are relying solely on ham radio for contact with the outside.  Jamestown has since been evacuated. "Everybody was huddled into the high school there," Ciaccia told ARRL. He was in contact with the mayor there and trying to get the community needed resources as soon as possible. Hams in Estes Park have been working out of the EOC in
the Town Hall, which is on high ground. "There's no place to go. Everything's flooded," Ciaccia said. "The only ham in Lyons was working out of an evacuation center at the local elementary school." He said the National Guard has been relocating some evacuees, as the shelter has become overcrowded.

On Saturday, September 14, US Congressman Cory Gardner (R-4) visited the state emergency operation center to express his appreciation to the Amateur Radio operators responding to the historic flooding
disaster. Rep Gardner asked Colorado Section Emergency Coordinator Robert Wareham, N0ESQ, to extend his thanks to all ARES members staffing positions in the field as well.

Boulder County has deployed miniature drone aircraft carrying Amateur TV cameras to survey the affected, more remote regions, for now to spot individuals who may need to be rescued. "We're still in a search-and-rescue mode," Ciaccia said, "not really in a damage-assessment mode."

Ciaccia said the drones - a fixed-wing aircraft and a hybrid gas/electric-powered helicopter - have been transmitting ATV video via UHF to the ground and simultaneously recording the video on a memory stick. The helicopter can remain in the air for more than 5 hours at a clip, recording images for officials at the EOC to evaluate. Ciaccia said Boulder County Emergency Coordinator Al Bishop, K0ARK, owns Reference Technology, the company providing the drones.

Ciaccia said that during the past year the Boulder County ARES team created the Mountain Emergency Radio Network (MERN) on its own time and money and put up two repeaters - one at Allenspark and another in Gold Hill. "The intent was to start educating people in the mountain regions to become hams," Ciaccia said. Some 65 individuals have gotten their licenses, and the team provided each with a radio.  "Those radios and those people - they became the eyes and ears for their communities," Ciaccia explained.

Allenspark Repeater location from http://bouldercountyares.org/

As power was lost, the only remaining means of communication were the two repeaters operating on propane-powered generators. "The system worked," Ciaccia added, "and we were able to utilize it for emergency communication purposes." Those communities have since been evacuated.

News media accounts citing the state Office of Emergency Management say 19 Colorado counties remain under a high threat of flooding. These include Boulder, Arapahoe, Weld, Park, Jefferson, Larimer, Clear Creek, Adams, Douglas, Broomfield, Gilpin, Denver, Logan, Morgan, Washington, El Paso, Teller, Pueblo and Elbert.

State authorities are warning residents in the hard-hit counties to stay off the road. Interstate 25 from the Wyoming line to Denver has been closed, along with part of Interstate 70.

LDS Guidelines for Emergency Communication

Because many of the blog viewers are LDS, I have included two links to lds.org that covers emergency
preparedness communications guidelines from the church.

Priesthood leaders may call communication specialists as needed. Communication Specialists may develop a plan that involves a variety of communication options (Internet-based technologies, text messaging, social media, amateur radio, satellite telephones).

HamTime - 10min Reminder Clock

Thanks to O.D. Williams, N7OZH, and his blog for finding this helpful software.

Have you ever forgotten to announce your call sign within the FCC required 10 minute interval?  HamTime has been created to help with that problem.  HamTime runs in the corner of the screen and gives you an audible alarm when that announcement is due.

 "This program was requested by a Ham radio operator. FCC regulations demand that you announce your callsign at least once every ten minutes, and HamTime runs in the corner of the screen and gives you an audible alarm when that announcement is due." 

Through the settings tab, you are able to adjust the interval of the alarm, select either an audio or visual alarm, input UTC time and your call sign.  The audio alarm sounds like a school bell.

Amateur Radio Public Service Events

A reminder if you are interested in volunteering your Ham Radio skills, to serve as a communicator for a special event, ARPSE.org has the following events through September:

This site has been established to link Amateur Radio (Ham) Operators with various public service opportunities in the state of Utah.  All throughout the year, Amateur Radio Operators volunteer their time and equipment to help support a wide variety of events.  These events include, but are not limited to, parades, walks, runs, and bike tours.  While Amateur Radio operators are primarily communicators, they in many cases get heavily involved in the actual operation of the event.  Whether it be helping to plan logistical support or responding to event emergencies, Amateur Radio Operators play a vital role in the health and safety of event participants and overall event success.

Back in 2007 this site was created as a public service to the Amateur Radio community.  Each year since then the site has continued to grow and expand and provides a service that enables Amateur Radio operators to give back to their communities through their hobby.

Radio Amateurs Comm Support in Boston Marathon Bombings

Story posted from ARRL.org
4/16/2013

As has happened many times in years past, over 200 Amateur Radio operators participated in communications for the Boston Marathon on Monday, April 15, 2013. Unlike prior challenging situations such as very warm weather for the runners or other weather-related challenges, this year’s marathon will be remembered for the bombings that took place at the finish line. Despite this heinous act, professional first responders, medical volunteers from the American Red Cross that staffed the route, and Amateur Radio operators performed magnificently in the face of adversity.

“Within minutes, cell phone systems became overloaded and making phone calls and text messages was difficult. Amateur Radio operators performed communication duties under duress and performed admirably. No Amateur Radio volunteers were injured on the course in this terrible act,” said Steve Schwarm, W3EVE, who is the Amateur Radio Course Communication Coordinator and associated with a consortium of clubs and groups known as Marathon Amateur Radio Communications (MARC).

“At the finish line net control, which was only 400 feet from the initial blast, we heard the explosion. I poked my head outside to confirm what I thought it was and saw the white smoke. We immediately knew what had happened and commenced a roll call of all ham operators and medical tents.  State Police authorities initially ordered us to lock down and post a ham for security watch outside the net control trailer. Thankfully none of our people were hurt,” said Paul Topolski, W1SEX, Amateur Radio Finish Line Coordinator.

Following the explosion and roll call, Topolski stated that they began pulling together updates and sent the information via the Massachusetts Emergency Management Agency (MEMA) Web-EOC software tool and provided updates via Amateur Radio. Shortly after sending a few updates both Boston Police and Massachusetts State Police gave the order for the tent area to be evacuated. “In my mind, the course end of things is where a lot of work needed to happen as runners eventually needed to be stopped, congregated and transported to safety and staging areas,” Topolski said. “At the finish line, our job was to check on the safety of our people, provide those initial updates and evacuate per police instructions. Three of our Amateur Radio operators redeployed to the Boston Marathon Course Net Control Center.”

Across the course outside of the finish line after the bombings occurred, first aid stations were consolidated to larger first aid stations to pool runners for pickup and to keep runners warm as there were enhanced tents along the route where runners could be kept warm and hydrated. At the Heartbreak Hill first aid station, amateur operators had a complete base station setup, including a computer, and were prepared to handle health and welfare traffic as required. Several shelters were set up along the route at churches and schools, and Amateur Radio operators from secured first aid stations went to those shelters, providing communications in those areas until runners were moved out of their locations.

“My role at the request of Steve, W3EVE, as event organizer before the race was to shadow the course medical tent coordinator for the Red Cross, Kandi Finch,” said Rob Macedo, KD1CY, who is also the Eastern Massachusetts ARES Section Emergency Coordinator. “It was a challenging position but all organizers on both the Amateur Radio side and Red Cross side said things went well in coordinating during normal race conditions and particularly after the bombings.”

At course net control, which was away from the bombings, ham operators controlled their nets calmly and professionally while also expressing an appropriate level of urgency. Over a dozen amateurs at the net control center pooled together to announce messages and keep status of changes along the course route as required.

Net Control Center Coordinator, Karen Brothers, K1KEB, kept in constant contact with MEMA, where Terry Stader, KA8SCP, was stationed. Stader became the MEMA ‘Ops’ point person at the State Emergency Operations Center as runners were transported from the shelters to other staging locations. From his location at the EOC, Stader was able to sort out the sheltering plan and reception centers for the runners, subsequent transport of runners from shelter locations and give out information on MBTA bus and train operations.

Jim Palmer, KB1KQW -- who served as a net control at the Net Control Center -- stated that nets were doubled up on operators, to allow one person to operate the radio while the other listened and logged priority calls and ambulance requests, creating a more efficient operation. “Several ambulance requests for dehydration and exhaustion were handled due to the runners needing to be stopped,” Palmer said. The specific net that Palmer ran also provided a link between the marathon course and the American Red Cross in its Cambridge facility. Lou Harris, N1UEC; Frank O’Laughlin, WQ1O, and Dan Howard, K1DYO, staffed the Red Cross in Cambridge.

Many amateur operators who volunteered along the marathon route praised Net Control’s support after the bombing. “Net Control did an awesome job,” said course volunteer David Wihl, KB1VEG. “The workload was busiest after seven hours on the radio, and it didn’t let up for another couple hours.”

Several young radio amateurs from the Clay Center Amateur Radio Club also supported Net Control Operations, both as direct net control operators and runners for the operation as they have done in the past. This provided a tremendous learning opportunity for these young operators, from both an Amateur Radio perspective and an overall learning perspective.

“Despite the total lack of warning in this situation, amateurs followed a creed I’ve long since preached since the 9/11 terrorist attacks and the mutual aid response to those attacks: ‘blessed are the flexible for they will not get bent out of shape,’” said Steve Schwarm, W3EVE. “Amateurs on the course did what they had to do to assure their own safety and runner safety working with the Red Cross medical people. They did an outstanding job and I was told so by Red Cross organizers as well.”

From an ARES perspective, a heightened state of awareness on the Boston Marathon event is typical, but within 15 minutes of the bombings, Eastern Massachusetts ARES Assistant Section Emergency Coordinator, Carl Aveni, N1FY, issued an ARES Stand-By and requested that amateurs give availability for the next 24 hours. Within minutes, 20 amateurs offered their availability.

The ARES sub-regional command center at the Acushnet, Massachusetts EOC (under call sign WA1EMA) was utilized as a control point to obtain critical situational awareness of the rapidly changing situation, as well as to monitor resource nets per a report filed by Acushnet Emergency Management Communications Officer Ed Caron, KA1RSY; he also serves as the South Shore Massachusetts ARES District Emergency Coordinator. A total of five Amateur Radio operators were deployed to this facility. An ARES resource net was called on the 147.18 Bridgewater repeater with Byron Piette, K1YCQ, as net control with 11 stations checking into the net.

“In terms of having amateurs within ARES who cannot get directly involved in the marathon, we have a process where we have them monitor in case of a situation like what occurred on Monday. That process paid off and facilitated a rapid response to our request for possible additional support,” said Carl Aveni, N1FY.

Some radio amateurs who volunteered in the Boston Marathon have posted their stories online; read one such story is from Tim Carter, W3ATB, of Meredith, New Hampshire.

WORLD AMATEUR RADIO DAY

Each year on 18 April, radio amateurs celebrate World Amateur Radio Day. On that day in 1925 the International Amateur Radio Union (IARU) was founded.

Amateur radio has truly entered the 21st Century. In less than 100 years amateur radio communications has evolved from crude spark-gap technology to digital signal processing and software-defined radios. The amateur's HF choice between voice and CW has been expanded to a broad range of communication choices from television to spread spectrum.

Amateur digital communications has evolved. At the end of World War II until the early 1980's, radioteletype, also known as RTTY, was the only HF digital mode available to amateurs. In the 1980's, AMTOR made its debut along with the increased popularity and availability of personal computers. AMTOR was the first amateur digital communication mode to offer error-free text transmission.

From the early 1980's, the rate of change increased dramatically. Packet Radio emerged and for a period of time was the most popular form of amateur digital communication. As microprocessor technology became more sophisticated, there was a rise in modes such as Clover, PACTOR, and G-TOR that were capable of error-free exchanges under marginal band conditions. In the late 1990's, there was an invention that harnessed personal computer technology to create PSK31.

In the VHF-UHF frequency ranges, Packet Radio had less activity at the close of the century than it did in the 1980's and 1990's. However, Packet Radio was reborn as the popular Automatic Packet Reporting System (APRS) and traditional packet systems still exist to support public service activities with greatly enhanced functionality.

Thanks to individual amateurs, hams now enjoy digital meteor scatter contacts and even moonbounce on VHF and UHF frequencies with modest stations. An ordinary computer sound device and software that can be downloaded free from the internet is all that is needed.

The Japan Amateur Radio League developed the D-STAR digital voice and data standard and there has been significant amateur growth as amateurs establish D-STAR repeater networks on the VHF, UHF and microwave bands.

All of these development have inspired amateurs around the world to experiment in their own HF, VHF, UHF and microwave band digital communication.

Activities on the occasion of World Amateur Radio Day  can be a great opportunity to spread the word about what the "hams" are doing in the 21st Century.

Training Comment for the SLC SE Division Net

Training for the April 3. 2013

Salt Lake City Southeast Division Emergency Preparedness Net

By T. Michael Smith (KM7TMS)

This is KM7TMS with tonight’s Training Comment.  About this time last year we were involved in Utah’s first ever Shake-out drill.  It was an exciting event despite the reduced monies that ended up available.  I know some of you participated as I did, and your presence helped make the event memorable.

This year we are all again invited to join thousands of people who will Drop, Cover, and Hold On at 10:15 a.m. on April 17th* in the 2013 Great Utah Shake Out!  I hope you have signed up to participate.  As of early evening there were 760,000 participants signed up for this basic drill.

Of course, this simple general public drop cover and hold on drill is directed to give us all the fundamental practice on what should be our initial response to an earthquake.  However, it is not all that is happening.  Like last time most of what happens will be outside of our court.  Various other agencies and organizations are doing various things.  For instance, my training comment for last November included a mention of how the Utah Preparedness folks stationed at the state capital were looking for volunteers who would want to learn the software utilized in tracking various donations given for sizable emergency events.  They intended to include such a record keeping aspect to their 2013 ShakeOut drill.

As public moneys are tight these days, not a lot is being spent.  Salt Lake City is apparently planning nothing, other than encouraging participation in the basic drill and organizations to do what else they may want to do.  This accents the ongoing importance of volunteer organizations like this net and the local CERT teams in our neighborhoods.  That is, when the agency first responders are busy it will basically be up to the local neighborhoods to tend to themselves until help arrives.

Living in the real world with limited resources and abilities, we should take this occasion to ask ourselves this question: are we better prepared than we were last year for a big quake.   I think I can say yes to that question -- in most aspects.  Susan and I have more supplies and equipment than a year ago.  But more importantly, because we have continued in our various preparation activities, we are more experienced, knowledgeable, and better networked than we were a year ago.  I hope all of you can say the same.

Beyond the personal situation we can ask ourselves if we have stronger, better prepared community groups than we had a year ago.   Many of us can say yes, and I will point to two examples of this.  For instance, the recent Southeast Division’s meeting on MESH technology held over at the Foothill Stake Center was surprisingly well attended.  Similarly, this not easy, but promising powerful new technology continues to generate interest around the wider valley, state and in other states.  In that same progressive manner, the CERT classes have continued to produce new CERTS and refreshed CERTS.  There is still much that needs doing in the CERT program, but there are now more of us in our communities.

Those found in the emergencies will best benefit from the preparedness we promote, and that promoting maybe the most important thing we can do.  Preparedness quickly becomes a shared activity, and good preparedness is a community endeavor.

With those important promoting and sharing thoughts I will conclude tonight’s Southeast Division Training Comment.  This is KM7TMS thanking you all for our attention and returning the mic back to net control.

Event:        HSMM-MESH introduction and demonstration
Location:    LDS Foothill Stake Center
                 1933 S  2100 E
                 Salt Lake City, UT

Date:         March 28, 2013
Time:        7pm - 9pm


Dear Amateur Radio Operators and other Friends,

You are invited to an introduction and demonstration of HSMM-MESH, particularly emphasizing some valuable applications and operations for emergency communications.  We will meet on Thursday, March 28 at 7 - 9 p.m. at the LDS Foothill Stake Center, 1933 S 2100 E.  (Although odd-numbered addresses in this area are usually on the east side of the street, this one is on the west side, across the street from Dilworth Elementary School.)  I am excited that Dave Bird (WA7RYV) will share his knowledge, skill and ongoing efforts with us.  He will include hands-on opportunities in his presentation which will excite you about utilizing mesh in disasters.

HSMM-MESH stands for High-Speed Multimedia Mesh.  You can read much more about this up-and-coming system at www.hsmm-mesh.org, but I'll give a quick overview.  Quotes are from that website.

Currently using certain versions of Linksys WRT54G, -GS, and -GL series routers, MESH is "being designed, developed and deployed as an amateur radio broadband communications system," focusing on emergency communications.  The wireless router "operates on channels 1-6 of the 2.4GHz ISM band, which overlaps with the upper portion of the 13cm amateur radio band."   

A router is connected via Ethernet cable to a computer and "flashed" or "upgraded" to a different free firmware and then functions through a web browser not  connected to the Internet.  The router, with or without accompanying computer, is called a "node," and multiple mesh nodes constitute a mesh network -- what one might call an intranet.  "Mesh nodes communicate with other nodes over Wi-Fi frequencies and only talk to other mesh nodes on the wireless port."  With a variety of software on the operator's computer,  "most tasks that you can do over a wired network will work on a mesh node," including data transfer/file sharing, shadowing another node, Internet-style chat, live feed from cameras, and telephone calls via Voice over Internet Protocol (VoIP).

Depending upon true line of sight, mesh nodes with auxiliary antennas "can easily have a range of 10 miles or more using stock power."  Nodes and the mesh are not connected via the Internet, and you cannot connect to the mesh from wireless devices such as computers or smart phones.  Some operators have established nodes on their homes or other buildings and have them running 24/7 so other nodes can establish a mesh with them.  Others have grab-and-go kits or drop boxes for portable nodes in emergencies.

A node connects to the strongest signal it can detect.  If the connected node becomes unavailable, the initial node will search for the next strongest signal.  The success and viability of a mesh is dependent on having lots of nodes so that one node can connect to another node, which also connects to another, which connects to another, and on.

A node in the mesh "wireless computer network . . . can run for days from a fully charged car battery, or indefinitely with the addition of a modest solar array or other supplemental power source."

Assuming an operator already has a computer to use for one of the nodes, developing a node can be relatively inexpensive, especially as used Linksys routers are available on the Internet and sometimes at thrift stores.  The firmware and software being used most at this time are free.  Some operators have put their transportable nodes in plastic laundry detergent or kitty litter containers.  Of course, operators can make nodes more complex and costly, depending upon his/her objectives, with amplifiers, antennas, weather-proof enclosures, cameras, VoIP phones, etc.

Although the node has to be identified with a ham callsign, the computer software can be run under the licensee's auspices by a non-ham, allowing a person who might be proficient in computer applications (or just plain available) to assist in communications during a disaster.

If you have not heard of MESH before now, I hope you will be interested in this meeting; come with a laptop computer in hand, if you like.  If you are acquainted with or have started a mesh node already, you are welcome to bring your node(s) or photographs for display tables; set up before the meeting and show-and-tell with other participants for a short while after the meeting.  If you have Ethernet cables, please bring them as we intend to set up only a few active nodes for the demonstration and link to everyone's computers.  If you have friends who are not amateur radio operators but interested in disaster communications, please invite them.

Come for an informative evening and a fun time meeting and greeting other hams.  After this presentation, you'll surely want to be part of a mesh!

Amateur Radio Public Service Events

This site has been established to link Amateur Radio (Ham) Operators with various public service opportunities in the state of Utah.  All throughout the year, Amateur Radio Operators volunteer their time and equipment to help support a wide variety of events.  These events include, but are not limited to, parades, walks, runs, and bike tours.  While Amateur Radio operators are primarily communicators, they in many cases get heavily involved in the actual operation of the event.  Whether it be helping to plan logistical support or responding to event emergencies, Amateur Radio Operators play a vital role in the health and safety of event participants and overall event success.

Back in 2007 this site was created as a public service to the Amateur Radio community.  Each year since then the site has continued to grow and expand and provides a service that enables Amateur Radio operators to give back to their communities through their hobby.

BSA to Offer Amateur Radio Operator Rating Strip

The Boy Scouts of America (BSA) has approved an Amateur Radio Operator rating strip for Scouts and Scouters to wear on their uniforms. According to BSA Communication Services Director Jim Wilson, K5ND, the strip recognizes the Scout or Scouter’s availability as an Amateur Radio operator for communication services for events and activities, as well as emergencies. All registered youth members and adult leaders who also hold a valid FCC-issued Amateur Radio license of any class are eligible to wear the rating strip.

Any Scout or Scouter who holds a current Amateur Radio license issued by the FCC is eligible to wear the Amateur Radio rating strip on the right sleeve of their uniform. The strip signifies to Scouts and the public that the wearer is a radio amateur who is capable and prepared to assist in providing communication services for events and activities, as well as emergencies.

“Last year, the BSA Awards and Insignia Committee introduced the Morse Code Interpreter Strip upon the recommendation of the BSA’s National Radio Scouting Committee,” Wilson told the ARRL. “We are always looking for ways to promote Amateur Radio, both within Scouting and to the world. The National Radio Scouting Committee thought this new Amateur Radio rating strip was a wonderful way to do exactly that, as it readily identifies to everyone that the wearer is a licensed radio amateur, prepared to be useful and to help others.”

Wilson, who heads up the National Radio Scouting Committee, said that the Amateur Radio Operator rating strip is similar to the Amateur Radio Operator badge offered as a proficiency badge by Scouts Australia, as well as the badge recently introduced by Scouting Netherlands. It follows in the footsteps of the Scout Radioman personal interest badge for Senior Scouts and Explorer Scouts that was offered by the Boy Scouts of America in the 1940s. The strip is worn on the right sleeve.

ARRL January VHF Contest - 
Perfect for ARES Practice, Too

The ARRL has added a new "FM Only" category to ARRL VHF contests, starting with the January VHF Contest, which begins this Saturday, January 19. The contest starts at 1900 UTC and runs until Sunday night at 0359 UTC. You'll find lots of "weak signal" VHF operators using high power and sensitive antennas working hard to work your station on FM. No special gear, no big expense -- you can operate in this contest and possibly win a certificate using just the radios you already own.

It's also a perfect opportunity for ARES, SKYWARN, RACES and CERT teams to test their ability to communicate without using a repeater, just as you might have to in an actual emergency. Want to have even more fun? Drive or hike to a local hilltop and you can exercise your deployment capabilities -- it's like "Field Day In the Cold!"

You'll find lots of VHF operators hoping to work YOU! Try transmitting a "CQ Contest" on the following frequencies: 146.550 MHz simplex; 146.580 MHz simplex; also 52.525 MHz (6 meters); 223.5 MHz (1.25 meters); and 446.0 MHz (70 cm band). Remember under the new rules, you're limited to 100 watts or less, but that means you'll be on equal footing with a lot of small stations. A gain antenna (like a beam or Yagi) can really help, and a high location is a big plus, too. You'll need to know your "grid square" as that is part of the exchange of reports with other stations.

**********

As the previous Section Emergency Coordinator for Alabama, I understood that FM simplex capability translated to a greater level of capability during an emergency. Amateurs who improved their stations on simplex, also benefited by being able to reach more distant repeaters, which is a huge advantage during severe weather. Some "lessons learned" from cross-promoting FM activity during VHF contests were:

1. Tailor your message to your audience. I didn't try to pitch it as a "contest" as much as an exercise when talking to ARES, SKYWARN, and CERT groups. We encouraged them to test their ability to communicate without the aid of a repeater, as they might have to do in an emergency. We also encouraged Field Day-type operations from high locations.
2. Concentrating activity in a three- to five-hour period is going to be more successful than just putting out the dates and times for a two-day long contest. Nothing is less interesting than "dead air" to a non-contester. (It's not all that interesting to a contester, either - N0AX.)
3. It's vital that weak-signal operators monitor the FM simplex channels and participate during those concentrated activity periods. I tried to utilize the afternoon hours on Saturday, when conditions are poorest---so that operators didn't miss out on a lot of contacts on SSB and CW but that doesn't work well in June when six meters is liable to be open.                                                                   The point is that weak-signal operators often turn their nose up at FM - and this hurts the effort. If you give a new operator a taste of DX, they may become hooked for life. The best way to accomplish this is to get those "monster signals" active on FM. If your local big gun doesn't support FM contesting, then try to change their mind on the topic.                                                                                      You should hear some of the reactions you get from newcomers when they discover they can communicate 75-100 miles or more on their FM rig without a repeater. This is easily possible with a high-performance weak-signal station on one end of the contact.
4. Talk up the event on your local FM nets, club meetings, etc. Tailor the message to the crowd. A DX club isn't going to respond to the same "pitch" as your local ARES team.
5. Poll your club and see who has 222 MHz FM capability. I always make it a point to schedule contacts with those operators on 223.5 MHz simplex.
6. In the last few days before the contest, make a lot of calls on 146.52 MHz and talk to operators there about the contest. They understand the concept of simplex and use it often. They're your best candidates for participation in the contest. Nothing in the rules forbids promoting the contest on 146.52 prior to the event!
7. Don't get discouraged by the naysayers. The FM-Only category is a great idea, but it needs the active support of the weak signal community to work!
