When it comes to DMR, people usually think of Brandmeister. But there is another network rapidly gaining popularity in North America worthy of your attention – DMR Plus. DMR Plus gives you many of the same features as Brandmeister such as talkgroups, SMS messaging, private call, reflectors and more. The main difference is DMR Plus presents these features in a well thought out manner which allows for outstanding flexibility when it comes to the way we communicate.

Doing a google search for DMR Plus comes up with the following from the DMR-MARC website:

DMR Plus is the original network that developed tools to interconnect ETSI Tier 2 DMR repeaters. It has been popular in Europe for years but now, with the cooperation of DMR-MARC, it has finally arrived in North America and the South Pacific. The DMR Plus architecture is similar to D-Star. Users have talkgroups to converse, to disconnect, and to monitor channel status. Users choose from a large pool of reflectors and move back to the converse talkgroup for all QSOs.

The DMR-MARC and DMR Plus partnership is ideal. The DMR-MARC network is robust and reliable. The DMR Plus network is more aligned with experimentation and interoperability of technologies. Think of DMR Plus as the best possible implementation of the former DMR-MARC Sandbox.

DMR Plus also supports a configuration that features the traditional DMR-MARC talkgroups like Worldwide English, North America, Latin America, etc. on TS1 and the DMR-Plus reflectors on TS2. The USA Regional talkgroups and the Canadian Provincial talkgroups are now connected to the TS2 reflectors.

Like Brandmeister, DMR Plus uses talkgroups (many of which are bridged between the two networks such as TAC310, World Wide 91 etc) but they also use reflectors. A reflector is kind of like a hub that allows you to communicate with everyone else that is also connected to that same reflector. But on DMR Plus, the reflector itself can be bridged to either another talkgroup, another reflector or even another network or digital voice mode.

One perfect example of this is the QuadNet Array. The Array brings the most popular digital voice modes under the same roof. You can find the QuadNet Array on reflector 4551 or DMR Plus talkgroup 320. By connecting to either of these your transmission can be heard by users on DMR Plus but also Brandmeister 31012, Yaesu System Fusion reflector 37099, D- STAR reflector XRF757A, Smart Groups DSTAR1 and more. For a complete overview of the QuadNet Array visit the QuadNet website at www.openquad.net.

You can also find an updated list of DMR Plus reflectors at https://www.dmr-marc.net/FAQ/dmrplus-america.html.

One thing that stands out in my experience is that DMR Plus appears to have better audio quality than Brandmeister. I find much fewer dropouts and lower packet loss on the DMR Plus network.

So, what do you need in order to give DMR Plus a try? If you are running a Pi-STAR based hotspot you are good to go. The OpenSPOT will also allow you to use DMR Plus. However since I have not had the opportunity to use one I am not able to give you specific setup instructions. Refer to the OpenSPOT website and Facebook group for more information.

In Pi-STAR version 4, do the following:

1. Login to your dashboard
2. Click on configuration
3. Scroll down to DMR Configuration
4. Under the DMR Master setting select IPSC2-Quadnet and click on apply settings.

While you can use any IPSC2 server you like, I recommend IPSC2-Quadnet because it is very well maintained and extremely stable. We make sure it is up to date with the latest software version which provides the newest features and bug fixes and I personally feel our technical support team is second to none. We are very responsive when it comes to support requests as well as adding requested DMR Plus talkgroups to the server. If there is a talkgroup you are having difficulty accessing on IPSC2-Quadnet send an email to [email protected] and let us know the DMR Plus talkgroup number and time slot and we will add it to the server.

Once your hotspot returns to the configuration page, enter the following in the options= box

StartRef=;RelinkTime=120;UserLink=1;TS1_1=320;TS1_2=;TS1_3=;TS1_4=;TS1_5=;

Once entered, click on apply changes.

What this line means is you are having our hotspot not automatically link to a reflector upon startup. If you want to setup a default reflector, enter the reflector number after the StartRef= command. RelinkTime means if you do link to a reflector it will automatically disconnect after 120 minutes if you don’t key your mic to reset the timer. If you have a default reflector set and change to a different reflector your hotspot will automatically return to the default reflector after the time expires. UserLink tells your hotspot to allow you to link to talkgroups and reflectors via RF. The TS1 lines setup static talkgroups. In this example I entered talkgroup 320 which is the QuadNet Array. I use the talkgroup for the QuadNet Array instead of selecting reflector 4541 because this allows me to monitor the Array and use reflectors at the same time. Very convenient when listening for a call while tuning around the various reflectors searching for activity.

Now in your radio code plug you will want to do the following:

Setup a contact for talkgroup for 320 and then add this contact to a channel and zone in your radio code plug. You will want to do the same for any other talkgroups that you would like to use and add them to your radio. Talkgroup 320 is what you would use to talk on the QuadNet Array multi protocol network. So if you have a friend that uses D-STAR, Yaesu System Fusion, Brandmeister DMR etc you can still talk with them on the Array. You can also use this talkgroup to talk with the administrators of the IPSC2-QuadNet server in case you notice a problem or have a question.

Add any reflectors that you would like to use (see the link earlier in this article to find the list of available DMR Plus reflectors) in your radio code plug as well. Any reflector you want to add needs to be setup as a private call in your contacts instead of group call. Then create a channel with the reflector contact that you just created, then add the channel to a zone. To link to a reflector you will then have easy access by selecting the zone you just programmed these into. When selected, key your mic and you should get an acknowledgement that you are now connected to that reflector.

You will also need to add a contact, channel and zone for talkgroup 9 (groups call, not private call) in your radio code plug. This is the talkgroup you will need to use when talking on a DMR Plus reflector.

While you are setting up your code plug, you will want to make sure you have your friends contact information setup in your radio and set these contacts as private call instead of group call. This is how you will initiate a private call to talk radio to radio outside of any talkgroups or reflectors. Private call is similar to call sign routing on D-STAR in that it allows you to talk with the other station radio to radio without using a talkgroup or reflector. The two of you can have a relatively private conversations and not get in the way of other users. You will also use this contact if you want to send them a SMS message.

I hope you decide to give DMR Plus a try. If you have any questions you can usually find me on the QuadNet Array talkgroup 320. If you prefer you can also contact me via email. I can be reached either at [email protected] or [email protected].

The magic band has always had a strong pull on me, ever since being put under its spell in the late 60s. I quickly learned that the surest way to guarantee a band opening was to leave the house for a few hours. Invariably when returning, the other local 6m addicts would gleefully describe everything that you had ‘just missed’. The 6m gods were rarely forgiving and this unfailing behaviour became part of the band's mystique.



This odd love-hate relationship continues to this day but with the FT8 mode being used almost exclusively now on 6m, it’s your computer that now snickers at you for any untimely excursions from the shack ... showing you, in any delightful color scheme that you choose, all of the DX that you 'just missed' once again!

It happened to me again yesterday, while out in the yard stacking next winter's firewood.

It was just a short excursion, as the eastern stations were working Europeans and all of the VE4 beacons were very loud back here on the coast. The possibilities of a link to the European path kept my excursion to only 10 minutes but sure enough, there it was on my WSJT-X list of decodes .... several CQs from CT7ANG in Portugal! My laptop could barely stop giggling. This would have been the first PNW-EU QSO of the summer had I been maintaining vigilance.l!

163315 -14 0.1 738 ~ CQ CT7ANG IM67
I continued to stack firewood and to watch the band more closely, knowing that every once in awhile, for entertainment purposes, the prop gods will toss out a bone or two, just to keep you on the hook.

A later check indicated that CT1HZE’s CQs had been decoded just a few moments earlier ... there was renewed hope!


185100 -2 0.2 2134 ~ CQ NA CT1HZE IM57

Joe’s strong FT8 CQ popped-up again a few minutes later and he came right back to my initial call. Although that was it for the day, the 2019 PNW-EU path had begun!

I’m still somewhat ambivalent about FT8 and its ‘coldness’ when it comes to person-to-person interaction, but since most of the DX action on 6m is now digital, it’s either embrace it or miss out. At the moment, I’m at least prepared to hug it and see how it behaves. If it puts more Europeans and new DXCCs into my magic band log, then that’s a worthwhile investment.

Unlike way too many others, I’m not prepared to let my computer endlessly CQ for hours at a time. In a crowded local environment, with big strong signals being the norm, this method of operating is simply disrespectful to other amateurs as this mostly useless CQing will usually make reception of any weaker signals impossible.

FT8 is a weak-signal mode and the interfaces used do not handle extremely strong local signals very well. I would urge others to think about this poor operating practice and adopt what has always proved to be the best tactic for catching DX ... listen, listen, listen. The same tactic works just as well on FT8 as it does on CW.

Back to stacking firewood but having tossed me a bone yesterday, I’m sure the prop gods will be out to get even for awhile!

Here is this week’s space weather and geophysical report, issued 2019 Jun 10 0314 UTC.

Highlights of Solar and Geomagnetic Activity 03 – 09 June 2019

Solar activity was at very low levels. No sunspots were observed on the visible disk and there was an absence of significant flare activity. A dissapearing solar filament (DSF), centered near S05E52, was observed in GONG optical imagery at 03/0715 UTC but was not observed in LASCO imagery. This CME was believed to have impacted Earth midday on 08 June. An additional DSF, centered near S05E13, was observed at 07/2145 UTC and is expected to have a possible geoeffective component with an anticipated arrival of 12 June.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 03 June and moderate levels on 04-08 June in response to elevated wind speeds from a negative polarity, coronal hole high-speed stream (CH HSS). The peak electron flux during the reporting period was 2,270 pfu at 03/1755 UTC.

Geomagnetic field activity reached G1 (Minor) storm levels on 08 June and unsettled levels on 09 June as a result of the aforementioned 03 June CME. Quiet conditons were observed throughout the remainder of the period.

Forecast of Solar and Geomagnetic Activity 10 June – 06 July 2019

Solar activity is expected to be at very low levels throughout the outlook period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 11-13 and 26-30 June, with moderate levels expected on 10, 14-20, 25 June and 01-03 July in response to elevated wind speeds associated with recurrent CH HSS activity.

Geomagnetic field activity is expected to reach active levels on 12 and 25 June, unsettled levels on 10-11, 13, 24, 26 June and 06 July due to CH HSS influence. Quiet conditions are expected throughout the remainder of the outlook period.

Today was my time to sit down at the PC and check out what amateur radio programs needed updating........now this has always lead me into a computer/software adventure. I use the word "adventure" loosely as it's more like a grey hair adventure. The programs I planned to tackle were:
                    - N1MM+ my contesting program
                    - WSJT-X my digi program
                    - JTDX my digi program I am testing out to see if I like it over WSJT-X
                    - Amateur contact log my logging program and sometime contest program
                    - WSJT-X JTAlert 
                    - Win4icom my Icom 7610 radio control program
                    -  Win4K3 my Elecraft KX3 radio control program

After I had finished with all that excitement it was then time to do a Windows update (running windows 7 64 bit pro), virus software which is Bitedefender and  malware software which is Malwarebytes.

The first program I tackled was N1MM+ contest program and this was one program I have updated many times in the past without issue. I thought this would be a nice place to start off the whole process. I had everything updated and install. When I started the program I was greeted with the message below on my PC.
It read "The remote server returned an error (404) Not found" so it would seem for some reason the great option this programs offers that it looks for new updates to the program and it informs you has an issue. I am  not sure if this is my issue or one with N1MM+ site. I will be later today posting on the N1MM+ user site for further info.
I then moved onto Win4icom radio control program for it's latest and greatest! All downloaded just fine and then when I started the program all was well and it connected with my rig no problem. I then tried to connect my logging program and Win4icom was not able to connect to it. I then went to the settings page of Win4icom and was greeted with the message below:
All of my Aux/CAT ports were now blank but fortunately this has happened to me in the past and  I now keep track of the port assignments. This was not a big deal but it still takes time to redo the whole deal.
My next task was to upgrade WSJT-X to the latest and greatest 2.1.0 rc7 and once done and I started it for the first time I was greeted with the message below:
In a nut shell it was telling me (which I knew) that this program was a per-release version but also (which I did not know) this program was not going to run this weekend. Since I wanted to see  how all my programs were getting along this was not going to do. So I just uninstalled this program BUT it seemed to uninstall ALL my previous WSJT-X programs so it was time to start from scratch and install the version I was using. Fortunately the DLL file was in-tacked and all my settings were loading and I was up and running in no time.
To keep track of my ports, order of program start up and some common problem fixes I have post it notes on the PC desktop.
 Win4k3 was very smooth but it has never been setup to communicate with any other programs at this point it just a stand alone program that controls my Elecraft KX3. WSJT-X JTAlert was the smoothest off all the programs to update.  The windows updates, malware update and scan and the bitedefender scan went off without a hitch. I was going to type that I was "all set to go" BUT software can be a funny thing and so I am just going to just leave to a warm fuzzy feeling inside and that's it.
