The Internet of Digital Radio by Onno Benschopu VK6FLAB
The topic of how radio evolves and embraces available technology is one that describes the hobby itself. From spark-gap through AM, SSB and FM our community picked up or invented solutions to make communication possible. When the internet came along it too became a tool ripe for picking and in 1997 a connection between a radio and the internet was made with the Internet Radio Linking Project or IRLP when Dave VE7LTD, a student at the University of British Columbia, joined the UBC Amateur Radio Society. Using a radio, some hardware and a computer, you could send audio between radios across the internet.
Since then this field has exploded with D-STAR, Echolink, DMR, AllStar, Wires, CODEC2, System Fusion and Brandmeister.
At a glance they're all the same thing, radio + internet = joy.
Looking closer there are two distinct kinds of internet radio contraptions, those where the radio is digital and those where it's not. IRLP is an example of an analogue radio connecting to hardware that does the encoding into digital and transmission across the internet. At the other end the reverse process, decoding, happens and another analogue radio is used to hear the result. This encoding and decoding is done by a piece of software called a CODEC.
If we continue for a moment down the analogue path, Echolink, AllStar and Wires do similar things. In 2002 Echolink made its way onto the scene, similar to IRLP, but it didn't need any specialised hardware, any computer running the Echolink software could be used as both a client and a server, that is, you could use it to listen to Echolink, or you could use it to connect a radio to another Echolink computer.
AllStar, which started life in 2008 went a step further by making the linking completely separate. It uses the metaphor of a telephone exchange to connect nodes together, which is not surprising if you know that it's built on top of the open source telephone switching software Asterisk.
In 2012 or so, Yaesu introduced Wires which is much like Echolink and AllStar. There are servers with rooms, not unlike chat rooms, where you connect a node to and in turn your radio.
Blurring the lines between these technologies happened when you could build a computer that spoke both IRLP and Echolink at the same time. Now you can also add AllStar to that mix.
Essentially these systems do similar things. They manage switching differently, handle DTMF differently, use a different audio CODEC and handle authentication in a variety of ways, but essentially they're ways of connecting normal hand-held radios, generally FM, to each other via the internet using intermediary computers called nodes. Before you start sending angry letters, I know, there's more to it, but I've got more to tell.
While Dave was busy in Canada inventing IRLP back in the late 1990's, in Japan the Ministry of Posts and Telecommunications funded research, administered by the Japan Amateur Radio League into the digitisation of amateur radio. In 2001 that research resulted in what we know today as D-STAR. Two years later, ICOM started developing D-STAR hardware which resulted in actual physical radios less than a year later. Today you can get D-STAR hardware from ICOM, Kenwood and FlexRadio Systems.
Unlike the other technologies where the audio was converted at a central place, in D-STAR the audio is encoded in the radio and a digital signal is sent across the airwaves. That in turn means that the software that does the encoding, the CODEC, needs to be inside the radio. Since the information is digital right from the point of transmit, you can send other information, like GPS locations and messages along with the audio.
In 2005 DMR started life as a group of companies, now up to around 40, agreeing on some standards for digital audio in much the same way as D-STAR. Mostly in use by commercial users, DMR has the ability to have two users simultaneously on-air using alternate channels by having separate time slots for each channel, alternating between the two of them. They agreed to use the same CODEC to ensure compatibility. Formal interoperability testing has been happening since 2010, but because DMR allows manufacturers to build in extra features many brands cannot actually work together on the same network.
For many years D-STAR and DMR-MARC, the DMR Motorola Amateur Radio Club World Wide Network, were the main digital radio systems around in amateur radio. That changed in 2013 when Yaesu introduced System Fusion. It too made digital audio at the radio, but it added a wrinkle by making it possible to have both analogue and digital audio on the same repeater. Depending on how the repeater is configured, analogue and digital radios can coexist and communicate with each other.
The Wires system that Yaesu rolled out was upgraded in 2016, renamed to Wires X and now also incorporates digital information to allow the linking of their System Fusion repeaters.
In 2014 at the Ham Radio Exhibition in Friedrichshafen in Germany, Artem R3ABM planned to make an alternative master server for DMR+ and DMR-MARC and the result was a German wordplay which we know today as Brandmeister. It acts as a network for digital radios in much the same way as DMR, but it's run as an open alternative to the commercially available options made by Motorola and Hytera.
The story isn't complete without mentioning one other development, CODEC2. It started in 2008 when Bruce Perens K6BP contacted Jean-Marc Valin, famous for the SPEEX audio compressor and David Rowe VK5DGR about the proprietary and patented nature of low data use voice encoders such as those in use in D-STAR, DMR and System Fusion. David had already been working in this area a decade earlier and started writing code.
In 2012 during Linux Conference Australia, Jean-Marc and David spent some time together hacking and managed to make a 25% improvement and CODEC2 was well under way. Today CODEC2 forms the basis of several projects including FreeDV in software, the SM1000 FreeDV adaptor in hardware and the roadmap for the future of open and free digital voice is bright.
I should mention that this information is specifically brief to give you an overview of the landscape and hopefully I've not made too many glaring errors, but feel free to drop me a line if you do find a problem.
Digital radio and the internet, it's not just a single mode, a whole cloud of modes, and I haven't even started with WSPR, FT8 or JT65.

The creator of APRS Bob Bruninga WB4APR says "I don't want to be an alarmist, but we need the Hams with the proper knowledge to get involved in this disturbing news"
His post on the AMSAT-BB, used with permission, says:
The National Electric Code now requires electronics on every module of a solar array communicating via signalling on the DC power lines to assure EACH pair of panels can shut down independently. This is to make all possible faults never allow more than 80 volts anywhere in the system. This is effective 1 Jan 2019
This is the nail in the coffin of simple DC series string arrays which are the quietest systems and almost demands microinverters oroptimizers on every panel. Refer to the QST article a few years ago about how disastrous optimizers are to RFI and HF operations with modules all over the roof.
Here is the Solar news:
Also, what is going to happen to an array that has signaling all over it in the near field of HF?
Although you can avoid it by going solar before then, you may have problems when your neighbors go later.
I hate to be an alarmist but we all know what happens when ham radio and commercial systems are incompatible and even though Ham radio might be in the right, we are only 1 in 600 and no one is going to side with us.
We took on broadband over power and squelched that dumb idea, but now this has the potential for equal demise of Ham radio. It should be fixable, but we also know that there is high competition in the solar market and the modules that are made the cheapest will be popular and will likely not be adequately filtered.
If nothing else, we need to find out what systems are terrible emitters and nip them in the bud. Maybe all it takes is driving by solar systems you see and turing on your AM radio on a weak signal channel and seeing if the background noise peaks near that home. But also it has individual peaks, so it might also be nice to tune around too find the max and then check the range. I find the noise can go hundreds of feet along the power lines.
You can't miss em... just sounds like a 60 Hz buzz on all the harmonics of the inverter switching frequency.

From Matt VE1BSG May 1st,
I wanted to pass on my congratulations and recognition to the Province’s newest set of licensed amateur radio operators!
Over the last four months this group has put in a great deal of effort and study both inside and outside the Province’s class, and has shown a great deal of interest in this hobby, which is also a great help to public safety during times of emergency. The examiners commented that both the interest and the diligence of the students was obvious when the final review occurred and the exam was written. We are proud to welcome this group into the amateur community, and know that their new privileges will be very useful in their roles as communicators and emergency management personnel.
Congratulations to you all!

They approached Trevor Munroe VE1TKM who is the fire chief, and asked him if he could put one on for them, he agreed. He obtained training information from Honorary Firefighter Shane McDougall VE1SMC. On April 7th, 2018 the group sat down with Bill Corkum VA1BC the local examiner from the Queens County ARC along with assistance form Howard Henderson VE1FV, and 4 out of 5 member passed there amateur radio course.
Two of them obtained Basic with Honors. They are Devon Whynot VE1DXW and Chris Whynot VE1CLS. The other two that passed with Basic are Nicholas Whynot VE1NJW and Byron Thorburne VE1BET. Michael Peach will be rewriting his exam at a later date.
Best of luck to you and congratulations to our new ham radio operators, and enjoy this hobby we call Amateur Radio.
From Jim VE1JBL Apr.7th
Not all amateurs are interested in DMR and some may not have the funds to purchase a radio yet but the prices have really come down in the past couple of years.
If interested in a weekly net please email me and let me know. You can also suggest a day and time to have a net. If you have questions, send them along.
There is also a poll on the Maritime Amateur Twitter feed @maritimeamateur where you can vote YES or NO to a weekly maritime net. This poll will be active for seven days.
As most of you know I like to promote the hobby the best I can. Saying that I have set up an email list for amateurs interested in digital radio in Atlantic Canada. I will share all the information I receive dealing with the mode including updates to repeaters and local nets as they come online. Send me an email letting me know you would like to be on this list and I will add you in.

From the February HARC Reflector
Brian reported that HRM has made the Club an offer to occupy two rooms on the upper floor of the Hammond Plains Fire Station #50 and HARC has accepted.
There will have to be a few upgrades made to the facility before we can take occupancy. There is also a large meeting room that we can book that will hold upwards of 40 people and will work for our monthly meeting.
There is a smaller room that is also bookable and will work for smallgroup meetings such as the Executive and our Basic Course.
Not having to rent our current monthly meeting room, will save the Club significant money. The plan is to move our tower from St. Andrews and put it up as a 56-foot tower with a beam and other antennae at the new location.
The actual move-in date is yet to be determined.

Net control was VE9DOH at Department of Health, Fredericton, headed by Al Thurber CG1RG contacted each health care facility. Operators at each facility reported those present and the equipment being used, and any particular comments on accessibility to the radio or the facility for the test. Over forty five (45) operators took part at twenty-one (21) facilities.
The test was a good demonstration to served agencies that amateur radio can be used as a back-up network in case of communication failures such as those experienced on August 4, 2017 when many cellular and internet connections were disrupted in the Maritimes.
The International Repeater Group maintains agreements with the Department of Health, and the Horizon and Vitalité Health Networks to assist with emergency communications. Each health care facility with an emergency room is equipped with an amateur radio as back-up.
