From Brad VE1ZX Nov.18th:
“For those interested in Yaesu's C4FM digital system (a.k.a. Fusion), my uncle (Brad Ross, VE1ZX) and I (VE1ZC) connected the VE1HPR Fusion repeater in Hammonds Plains (145.490-) to Yaesu's WiRES-X network yesterday night. The repeater is now part of a worldwide digital network. VE1HPR will normally be connected to the "CQ-Canada" room that is hosted by the Truro ARC (VE1AO). At any point in time, there are usually 12-20 repeaters and private nodes from across the country connected to the CQ-Canada room.
Wednesday evenings at 10pm Atlantic time, the CQ-Canada room hosts a
weekly net (with net controller Denis Rule, VE3BF) and the number of
connected repeaters and nodes can hit 30 with additional connections
from the US and overseas.
those interested in Fusion, Yaesu has a sales promotion on right now
with instant rebates on various models of Fusion radios.

I thought I would post a picture of the VE9GCS radio shack. It is a little messy but that is because the Mrs. is not allowed in here. This is the control point for the Moncton Area 2 meter simplex net and the 2 meter SSB net on Sunday nights.
From Lorne VE1BXK Oct.26th:
Eric VE1JW and Brian VE1IQ were successful in getting the RF QRM from the MFJ-1274 TNC's at the VE1WN packet installation at the Stronach Mountain site this morning as per my suggestion of using aluminum foil to hopefully snuff out the offending RF harmonics from both the MFJ-1274 TNCs. This is most likely the best the VHF LAN packet has worked since it originally installed many years ago.
Hats off to both Eric and Brian for a job well done after several trips! Thanks to Eric for the photos.

Memories of Jack Leahy VE1ZZ
VE1ZZ was not only a personal friend to many of us - he was probably one of the finest Topband Dx'ers ever to have lived. He goes back to not long after W1BB came back on the band at the end of WWII - and was one of the strongest signals I have ever witnessed on Topband. His signal was almost LEGENDARY all over the world. EU stations used to say - "He is almost as loud when he calls in Asian pileups as the EU callers are over here"...and that says it all!
Jack Leahy was personally responsible for my migrating to VY2ZM and was here at my home twice - once is 2002 and once in 2012. I last visited him and Opal (his XYL) in August of 2014 with Mike OE6MBG who wanted to meet Jack and see his QTH .
When I finally had the time after building my house here on PEI to visit Jack which was probably in July of 2003 or 2004, at first blush his place did not make a huge impression on me because it had only a short triangular portion of land at the road in the Head of Jeddore NE of Halifax - and the land rose rapidly behind his home. One initially wondered "How does he get out so well from here down at the road?"
The answer came shortly thereafter - Jack took me out behind the house - and we climbed that hill - up and up and up for something like a MILE - it was a pizza slice in shape and very wide at the top of the hill in the woods - with only about 100 feet (if that) at the road front side of the parcel.
Some distance up the hill was Jack's 160m 4sq array - which was made of ROHN 6 tower - that was sitting on 18 wheeler truck tires as base insulators. The towers were not tall - perhaps 55 feet or so and the rest of each radiator was wire - so it was really a WIRE inverted L 4sq. Jack was the "ultimate scavenger" and his radials were all 1-2" diameter pieces of HARDLINE!!! Hundreds of them all over the hillside I think he had a friend in CATV or at his local dump - but he got most of it for next to nothing he said.
From that point of his land, he could reach around the HILLTOP on 160m to acquire a clear shot to EU and the South was wide open and to the SW was also clear looking over the water. Looking straight up the hill was probably blocked to some degree - but often this does not matter all that much on Topband.
The day I was there was shortly after Jack had managed to communicate across the pond on what I think was 600m - I may be wrong about the frequency - but the antenna he used to make the SLOW SLOW SPEED CW contact was something out of this world!
It started about 1/3 of the way up the hill - and ran all the way to the rear of the property to near the furthest reaches of his land - and this was a LONG LONG LONG walk to get there - through some land that I recall was swampy. It had to have been at least 3000 feet long.
Part way up the hill, Jack had built a small shelter in which he placed the BIGGEST homebrew loading coil I have ever seen. It was about 4 feet tall and about 8 feet in diameter and wrapped around some kind of coil form he had created.
Jack explained that it took him awhile to resonate the system to his desired operating QRG - and this was done by taking a pair of alligator clips and through trial and error he tapped the coil he made - trying to use a DC ammeter to find the point of peak current into the system - which he explained seemed to indicate the system was reasonably matched.
His was among the first to work across the pond with that antenna - just one of his many achievements.
When I was in the US Navy stationed at Bremerhaven, Germany I used to listen to Jack and W1BB on 160m. W1BB would sit around 1801, KV4FZ often was around 1803 and Jack was down at the low end as well - calling CQ listening QSX up at around 1825-1830 in what was then known as the "DX Window".
Jack had a huge signal even then - using equipment that was popular in that era. I recall a Hammarlund HQ 160 Rx or something close to that model - there is a photo of that station from the late 1950's in my book "Dx'ing on the Edge."
Jack's More Recent Station - Inside
When I first visited Jack in 2003/2004, it was in his old house - not the newer one he built further up the hill some years later. The station was vintage (much like my own on Cape Cod) - and Jack used a TS830 driving a HB amp to something around a KW DC input. Jack's operating table gave me a chuckle because there was only about 4 inches of space between the front panel of the radio and the edge of the table. Jack was a "leftie" and placed his paddle parallel to the front of the TS830 and did his best to keep his forearm on the table while he sent.
Jack's keying system triggered a bunch of interconnected relays as he operated and he had quite a number of vintage antenna switches which selected his many Rx antennas.
After visiting his shack, Jack later showed me around other parts of the rest of the house - and I recall several rooms CHOCK FULL of stuff most of us would die for. One room was full of EIMAC xmitting tubes - 4-400's, some 304TL's, some 4-1000A's etc
Another room had shelves loaded with vacuum relays and vacuum variables he had collected over the years. Not one or two - but something like a 100 of them. There were also rotary inductors for HB design and many other things that made me drool.
I think I remember a third room full of vintage ham radio gear as well. Older stuff he had used previously over the years I guess.
I will relate one story about Jack when I was operating at 7O6T over in Yemen in 2012 I think it was. I was calling CQ arond 1823kHz waiting for SS to occur in NA - and this bone crushing signal came at me that almost blew me out of my chair. You can listen to this clip on my VY2ZM website - and you will see what I mean.
I told Jack that I was operating in the snippet - and later asked him to please tell me when OTHER NA stations were calling. I said, please do NOT tell me the calls - just tell me that USA stations are now hearing me and calling me. Jack did as I asked and about 15 mins later a very weak in the noise caller was Dave Patten, NN1N who was probably 3-4 S units down from Jack's signal. Dave's station is first rate - but there is something truly magical about operating from the Maritimes along oceanfront property. It is just how things work - Jack had what I call the "front door" to the NE path and it often shows up as it did that evening at 7O6T.
Here's how to listen to what I heard:
1) Go to http://www,vy2zm.com
2) Select the sound bites tab
3) Click on Sound Bite #4 and play VE1ZZ - Booming.
4) If you also wish to hear NN1N's piece look further down the list to hear the difference in signal levels.
JACK's last years
I last spoke with Jack in the summer of 2016. He told me he then had COPD and that his amp needed repairs and that his antennas were largely broken. I had heard him sparingly in 2015 and probably not at all in 2016 - and that explained why.
JACK's 160m DXCC Achievements:
For many years JACK held the #2 position WORLD in the Topband DXCC rankings. He finished his legendary Topband career at 334 countries confirmed at position #6 in the current rankings. This is only a HANDFUL of entities below that necessary to have qualified for DXCC HONOR ROLL - single band 160M. His mild, unassuming manner was also the measure of the man. He would stop DX'ing and work ANYONE who called him - which says alot as well. His was a special person and I have always admired him and what he managed to do in HAM RADIO.
Not only did he make DXCC on 160m - in the summers he got me hooked on 6M and he had a 6M DXCC as well - just to keep himself occupied during the summer doldrums on 160M.
I will close now and stop reminiscing about Jack - but I think it is altogether fitting that we stop and pause a moment to remember this fine 160M operator and gentleman and what he achieved on the band we all love to operate. He will always occupy a special place in our memories of Topband!

From Eric VE1JW Oct.16th:
The task was to move VE1BO and it associated equipment in the NSARA Rack to the new building at the site. Thanks to Neil's truck we were able to move the rack with most of the equipment still in the rack. This saved us an immense amount of time. Once the rack was in position and secured to the floor reassembly commenced. AC power was connected to the rack, equipment was
connected to feed lines to the antennas on the new tower, all equipment connections were verified and an upgrade was done to the repeater controller. Power was applied, all equipment was tested, cleanup was done and we were on our way home at 5:30pm.

From Dave VE1EDA Sept.16th:
The Halifax Auxiliary Telecommunications Service (HATS) is an operational vehicle through which HARC contributes to emergency telecommunications when a man-made or natural disaster strikes our community. This service is a joint effort of amateur radio clubs in the Halifax region and functions under the direction of the Emergency Management Division of Halifax Regional Fire and Emergency (HRFE).
NEWS: We held our first public demonstration and field Exercise on 6 – 8 July at Scott Manor House, a heritage property and museum in Bedford. Eight HATS members staffed the three-day event and interacted with visitors. We demonstrated our WinLink System by originating messages to various points in the HRM and communicated by voice with fixed and mobile stations over the VE1PSR and VE1HNS repeaters. A popular hands-on-activity was teaching visitors how to send their name in Morse Code. This event was an effective way to practice our communications skills, and to tell the public about amateur radio and its role in emergency communications. This is a model we will continue to use.
In the spring we initiated the HATS Leadership Program., an organized effort to recruit members who have leadership capability and are interested in developing it. I am pleased to report that over the summer we have had a good response, and we will begin working with 4 or 5 candidates this fall. I will provide more details about our current Leadership Candidates and their program in my October report.
Since training and practical exercises are the key part of our preparations to provide emergencies communication services, we will be offering courses this fall, including the Basic Message Handling Course, ICS-100 and Use of TMR Radios. As soon as dates are set, I will send out a training bulletin to all members. Remember that free ICS-100 training on-line is always available. If you want to pursue this independent learning opportunity, I can provide you with the URL and a necessary access code.
Our Third HATS General Meeting is scheduled on Thursday, 11 October from 7:00 – 9:30 pm at HARC’s new Club location in Fire Station #50 on Hammonds Plains Road. Matt Boyle, VE1BSG, who is with the NS Government’s Public Safety and Field Communications Office will make a short presentation on Threats to Radio. Communication. The program also will include a HATS update, plans going forward and group discussion as well as a chance to socialize with one another.
UP COMING EVENTS:
19 September (Wednesday) at 18:30 hrs. – HARC Monthly Meeting. It will feature Steve Frost, VE9SF talking about Wireless MESH Networks for Ham Radio
20 September (Thursday) at 1000 hrs. HRFE/EMO – Radio Advisory Group Meeting at the Eric Spicer Building on Mt Hope Drive in Dartmouth.
11 October (Thursday) from 19:00 – 21:30 hours a General Meeting of HATS will be held. Matt Boyle, VE1BSG, will speak about Threats to Radio Communications.
In October, Jim Calvesbert, VE1PPA, will be taking over from Joe MacPherson, VE1CH, the maintenance of our time and travel data, and making a regular report to HRFE Division Chief Erica Fleck. This is record of how much volunteer time and travel kilometers we accumulate each month in service to the HRM. Thus, it is vital information that demonstrates the value we provide to the HRM in return for the financial and organizational support we receive. This does not work without each member doing their part – regularly reporting their data. It is important to submit your data sheets, even if there is no activity for the month. It will show you are present!
Note that the HARC Program this month is on a topic of direct interest and importance to emergency communications, namely Wireless Mesh Networks for Ham Radio. Please plan on attending.
Do you want membership information? Please contact Dave Musgrave, VE1EDA. He is our membership officer and will see that you get the necessary information and application forms. His contact information is via email: [email protected]

Contact Manager 2.60 Released
We have just released N0GSG Contact Manager version 2.60. N0GSG Contact Manager is the "goto" software for working with codeplug data in many different makes of DMR radios, including Connect Systems, Tytera, AnyTone, and others. It allows you to freely edit information in all supported codeplugs, and also allows you to migrate data freely between any supported radio types using copy and paste commands for individual elements (such as contacts, channels, or zones), or Structural Import for migrating complete codeplug structures seamlessly.
Version 2.60 incorporates support for the new TYT MD-UV380, an enhanced DMR Database Search Facility, and for radios with multi-bank zones, a Mirroring Command to copy between A and B sections of these zones.
Everyone is aware of the impact that GDPR has had on the DMR databases. Ham Digital serves all DMR ID records worldwide, but due to GDPR, it's unable to provide detailed information on registrants beyond first name and callsign. Thankfully, Radio ID provides the missing data for non-European DMR users. But these are two distinct databases, which is hard to resolve for individual users. The enhanced DMR database search routine in Contact Manager now seamlessly merges the data from both sources so that you automatically get the best information available from both databases. Additionally, we've refined and expanded the DMR Online Database Searcher to allow you to enter additional search information that's "remembered" between Contact Manager sessions. For example, if you commonly wish to update your radio's contacts from specific regions, cities, or countries, you can enter those as additional search items, which Contact Manager will then automatically search for you each time you use the DMR Online Database Searcher.
Within the DMR Online Database Searcher we've also added a new CSV Contact Exporter that will allow you to export properly-formatted CSV contact files for radios such as the MD-2017, MD-9600, and MD-UV380, so that you can load additional contacts (up to 100,000) for these radios. The same enhancements applied to the DMR Online Database Searcher have been applied to the CSV Contact Exporter, so you can do this in just seconds with just a few mouse clicks.
The documentation for Contact Manager is updated and explains how to use the new features.
N0GSG Contact Manager is delivered via secured servers that are scanned daily for malware. Our site and software are 100% safe for your computer (we can make this claim only if you download Contact Manager direct from our site at http://n0gsg.com/contact-manag er/). It is well known that certain anti-virus software (including Windows Defender) is notorious for delivering false-positive reports. You may view an authoritative scan of this entire site and its content by visiting Virus Total.
We welcome your input on this software and very much appreciate your support for the Contact Manager project.

We are happy to announce we now have a means of connecting hotspots to the NBDMR system. At this time it is purely experimental, and limited to TS2. Performance may vary, but so far it does seem to work well.
We invite you to try it out and we want your feedback, please let us know if you try it and any issues encountered.
The currently silent packet radio system on the International Space Station could be back on the air by year’s end.
Amateur Radio on the International Space Station (ARISS) hardware team members have located an original duplicate of the packet module that had been in use on the International Space Station (ISS) before failing more than a year ago after 17 years of service. With a new battery installed, the unit was tested and found to be functioning. The ARISS packet system in the space station’s Columbus module, operating on 145.825 MHz, quit last July after first experiencing some problems. All necessary paperwork has been completed to manifest the packet module on the Progress 71P spacecraft launch now set for Halloween, with docking on November 2.
“Installation date will depend on the crew’s busy schedule, but ARISS hopes packet can be online again by the end of November 2018,” ARISS said this week in a news release. ARISS said it’s heard from “many hams” who have been asking when the packet system will be back on the air.
When the ARISS packet module aboard ISS died in last year, the ARISS hardware team already was overburdened with the design and safety certification of the new interoperable radio system ARISS has been developing that’s set for launch next year. The team did attempt some basic troubleshooting of the old packet module but was unable to revive it and decided instead to dedicate all of its time to the new replacement radio system, including packet capability.
Early this year, thermal testing of the first flight-identical power supply for the new comprehensive radio system showed that some changes to air flow were needed. This change would delay launch of the new radio equipment from late 2018 to early 2019.

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 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!
