Amateur radio

excerpt -
History

The origins of amateur radio can be traced to the late 19th century, but amateur radio as practiced today began in the early 20th century. The First Annual Official Wireless Blue Book of the Wireless Association of America, produced in 1909, contains a list of amateur radio stations. This radio callbook lists wireless telegraph stations in Canada and the United States, including 89 amateur radio stations. As with radio in general, amateur radio was associated with various amateur experimenters and hobbyists. Amateur radio enthusiasts have significantly contributed to science, engineering, industry, and social services. Research by amateur operators has founded new industries, built economies, empowered nations, and saved lives in times of emergency. Ham radio can also be used in the classroom to teach English, map skills, geography, math, science and computer skills.

Yowbarb Note: Just a few facts about HAM (I'm learning.)
...
https://en.wikipedia.org/w/index.php?title=Amateur_radio&redirect=no

Amateur radio (also called ham radio) describes the use of radio frequency spectra for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation and emergency communication. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;"[1] (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.).

The amateur radio service (amateur service and amateur-satellite service) is established by the International Telecommunication Union (ITU) through the International Telecommunication Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual stations licenses with an identifying call sign. Prospective amateur operators are tested for their understanding of key concepts in electronics and the host government's radio regulations. Radio amateurs use a variety of voice, text, image, and data communications modes and have access to frequency allocations throughout the RF spectrum to enable communication across a city, region, country, continent, the world, or even into space.

Amateur radio is officially represented and coordinated by the International Amateur Radio Union (IARU), which is organized in three regions and has as its members the national amateur radio societies which exist in most countries. According to an estimate made in 2011 by the American Radio Relay League, two million people throughout the world are regularly involved with amateur radio.[2] About 830,000 amateur radio stations are located in IARU Region 2 (the Americas) followed by IARU Region 3 (South and East Asia and the Pacific Ocean) with about 750,000 stations. A significantly smaller number, about 400,000, are located in IARU Region 1 (Europe, Middle East, CIS, Africa).

Emergency Communications will be a major theme of this years event:

http://hamvention.org/hamvention-seeking-emcomm-vehicles-for-static-display/

DAYTON HAMVENTION® EMERGENCY COMMUNICATIONS UNIT DISPLAY

Emergency communications groups such as ARES, RACES, MARS, CERT, SALVATION ARMY, DHS, NATIONAL GUARD, CGAUX or any groups who have a sincere interest in emergency communications are invited to display their emergency communications TRAILERS, VANS, TRUCKS or other displays at Dayton Hamvention®.

This is an opportunity to show off working units and their capabilities to the 25,000+ attendees at Hamvention. There are many groups that are thinking about building units and would get beneficial ideas from displayed units.
Set up is on Thursday May 19, 2016. The order of arrival and parking depends on the type of displays and their size.

General admission tickets are provided for 5 people and two parking passes included. The coordinator will require the names and calls of the display’s team to receive a ticket.
Please consider to have units fully manned, functional and demonstrate its capabilities throughout the show.  Organizers encourage teams to have flyers or handouts describing the unit its parent organization organization. Remember, this is also about sharing information and ideas!
Organizers hope to hear from interested parties as soon as possible as space is limited! Please contact NJ8BB, Gary Hollenbaugh to reserve a space at the EMComm Display!

GREAT article about HAM Radio Emergency Communications:

When everything else fails, amateur radio will still be there—and thriving
Ham is now a full-fat fabric that can provide Internet access. Why aren't you using it?

http://arstechnica.com/gadgets/2016/06/when-everything-else-fails-amateur-radio-will-still-be-there-and-thriving/

It’s a good time to be technical. Maker communities are thriving around the world, tools and materials to create and adapt are cheaper and more powerful now than ever, and open source hardware, software, and information mean that if you can think it, you can learn how to do it and then make it happen.

For one group of technological explorers, this is more than just a golden age of opportunity: it’s providing the means to save one of the oldest traditions in electronic invention and self-education, one that helped shape the modern world: amateur radio.

Radio amateurs get a sweet deal, with effectively free access to many gigahertz of the same radio spectrum that companies pay billions for. They’ve earned it. Throughout the history of electronics, they’ve been at the borders of the possible, trying out ideas that commerce or government deem impossible or pointless—and making them work. Here's one example of hundreds: Allied military comms in World War II needed a way to reliably control the radios used by front-line forces, replacing tuning knobs with channel switches. Hams had the answer ready and waiting—quartz crystal oscillators. (Those are part of computing history, too. You’re probably using about 10 of them right now.).

Then, there’s backup. Take the European HAMNET, for example. That’s a four-thousand-node high speed data network covering a large part of continental Europe and providing full IP connectivity at megabit speeds. It connects to the Internet—ham radio owns 16 million IPV4 addresses, believe it or not—but is independent of it, doing its own robust and flexible routing. If the Internet was to go away, HAMNET would still be running. The same’s true of nearly all ham radio infrastructure. When everything else fails (power, comms, roads), ham radio is still there. These days it can even be a full-fat digital medium.

An important bill just passed the House for HAM Radio and Emergency Communications!

Amateur Radio Parity Act Passes in the US House of Representatives!

http://www.arrl.org/news/view/amateur-radio-parity-act-passes-in-the-us-house-of-representatives

09/14/2016

“The bill is passed without objection.” With those words, Amateur Radio history was made on September 12, when the US House of Representatives approved the Amateur Radio Parity Act, H.R. 1301 on a voice vote under a suspension of the rules. The focus of the campaign to enact the legislation into law now shifts to the US Senate. The House victory culminated many years of effort on ARRL’s part to gain legislation that would enable radio amateurs living in deed-restricted communities to erect antennas that support Amateur Radio communication. The measure calls on the FCC to amend its Part 97 rules “to prohibit the application to amateur stations of certain private land-use restrictions, and for other purposes.” While similar bills in past years gained some traction on Capitol Hill, it was not until the overwhelming grassroots support from the Amateur Radio community for H.R. 1301 shepherded by ARRL that a bill made it this far. The legislation faces significant obstacles to passage in the US Senate, however.

“This is huge step in our effort to enact legislation that will allow radio amateurs who live in deed-restricted communities the ability to construct an effective outdoor antenna,” ARRL President Rick Roderick, K5UR, said. “Thanks to everyone for their help in this effort thus far. Now we must turn our full attention to getting the bill passed in the Senate.”

ARRL Hudson Division Director Mike Lisenco, N2YBB, who chairs the ARRL Board’s Legislative Advocacy Committee, has been heavily involved in efforts to move H.R. 1301 forward. “This has been a multiyear effort that is finally seeing some light,” he said. “The passage of the bill in the House is a major accomplishment, due to the hard work of so many — from the rank-and-file member to the officers and directors.”

Lisenco said it’s not a time to rest on our laurels. “We are only halfway there. The focus now shifts to our effort in the Senate,” he said. “We are beginning a massive e-mail campaign in which we need every member to write their two Senators using our simplified process. You will be hearing from President Roderick and from your Directors, asking you to go to our ‘Rally Congress’ page. Using your ZIP code, e-mails will be generated much like our recent letter campaign. You’ll fill in your name and address and press Enter. The e-mails will be sent directly to your Senators without you having to search through their websites.”

Lisenco said getting these e-mails to members’ Senators is a critical part of the process. “Those numbers matter! Please help us help you by participating in this effort,” he said.

As the amended bill provides, “Community associations should fairly administer private land-use regulations in the interest of their communities, while nevertheless permitting the installation and maintenance of effective outdoor Amateur Radio antennas. There exist antenna designs and installations that can be consistent with the aesthetics and physical characteristics of land and structures in community associations while accommodating communications in the Amateur Radio services.”

During this week’s limited debate, the House bill’s sponsor, Rep Adam Kinzinger (R-IL), thanked ARRL and the Community Associations Institute (CAI) for reaching an agreement to move the bill forward “in a bipartisan and very positive manner.” He pointed out to his colleagues that Amateur Radio antennas are prohibited outright in some areas.

“For some this is merely a nuisance,” Kinzinger said, “but for others — those that use their Amateur Radio license for life-saving emergency communications — a dangerous situation can be created by limiting their ability to establish effective communication for those in need.”

Kinzinger said that in emergencies, hams can provide “a vital and life-saving function” when conventional communication systems are down. He also praised the Military Auxiliary Radio System (MARS), a US Department of Defense-sponsored program, comprised largely of Amateur Radio volunteers, that also supports communication during emergencies and disasters.

Stay connected in remote areas with GoTenna Mesh


http://www.foxnews.com/tech/2016/09/30/stay-connected-in-remote-areas-with-gotenna-mesh.html


GoTenna Mesh
pcmag

By Ajay Kumar Published September 30, 2016

GoTenna, which created an off-the-grid communication device of the same name that earned our Editors' Choice, is rolling out a new product—the GoTenna Mesh.

Where the first GoTenna product was able to carry out point-to-point communication using VHF (Very High Frequency) radio, the new product can set up a long-range, consumer-ready mesh network.

"We're addressing something bigger than just unreliable service," says GoTenna co-founder and CEO Daniela Perdomo. Mesh differs from the first generation GoTenna, which is limited to sending a message between two individuals or a select group of users within range of each other. The Mesh operates on a different frequency, selecting publicly available frequencies on the UHF spectrum. This allows it to be sold internationally, since it isn't subject to the same regulations that hampered some aspects of the first GoTenna.


The Mesh can also send one-to-one messages with text and GPS over long range, but most importantly, it can use a technique known as store and forward to create a mesh network and extend range. So the more GoTenna Mesh users there are, the stronger the network range and connectivity will be, increasing what people can do while remaining a compact, off-the-grid device with no fixed nodes.

Perdomo talked up "people-powered connectivity" that runs in tandem with traditional communications infrastructure. "We're set on redefining communication based on need as opposed to access, and with GoTenna Mesh, we're one step closer to achieving this on a larger scale," she said. "It starts being useful when you don't have service, but we believe mesh networking of this kind will soon be a part of the everyday communication stack."

Finally, GoTenna Plus is a $9.99 per year subscription service launching alongside the Mesh, allowing users to take advantage of special features like topographic maps, trip statistics, automated location tracking, sharing with trusted contacts, group delivery confirmation, and network relays into traditional SMS.

I have done quite a bit of research on civilian HAM radios. I always thought the HAM was the equivalent of the military HF radios. Military HF works from 1 MHz to generally 30.00 MHz. I know these crews well, however if solar activity is high, you lose the ability to make a long range shot. Our radios were 20 watts output power, which you can increase the gain of by 16db by going to a full wave antenna.

The civilian HAM radio I have operates: 136-174 MHz & 400-480 MHz. These are UHF freqs, and I am very familiar with UHF. It is definitely the most clear frequency range there is. Pilots use this range, as well as space operations and satellite communications.

To build a field expedient antenna for UHF, you need either a Yagi antenna format, or a heck of a lot of wire for a quarter wave antenna.

I also still have an antenna handbook if anyone wants a copy, pm me with your email address.
It also discusses wave propogation theory.

Erv,

Actually, the US HAM VHF (2m) band is 144.000 -> 148.000 MHz and the UHF (70cm) band  coverage is 420.000 -> 450.000 MHz.  ;D

Sorry,

I have been silent for awhile, 2 new additions to the family and I have started a new business, you guessed it, "commercial communications" where I live so . . . I do have solutions, and I am more than willing to help!  I am glad you have kept this thread alive, sorry for the loooong silence, things have been 'cooking' in the oven of life!   ;D

(Natural News) It’s crucial that you have the right communication equipment during emergency situations. Your ability to communicate with the right people can spell the difference between life and death. Having the right communications tool can save you during times of crisis. That being said, there are five essential communications devices you must have during emergency situations, according to SecurityandSelfReliance.com.

NOAA emergency radio with specific area messaging encoder –

Battery-powered AM/FM radio – Emergency situations sometimes mean going back to the basics.

Scanner radio – A scanner radio can scan for and locate channels that may offer a lifeline during times of emergency.

Two-way radio – A two-way radio creates a private communication line between people who are tuned in on the same channel, letting you keep in contact with your group during emergencies

Portable shortwave radio – A shortwave radio can communicate over long distances — you can listen to broadcasts from other countries — and in real time.

Communication is essential in a disaster. If you prepare accordingly, you will come out of any emergency situation unscathed. With the kind of technology available to us, it should be easy to create contingency plans for your family.
