The CPS “Optional Settings” dialog and then “Display” tab has an option for “Call Display Mode” and that is a choice between “Turn Off Talker Alias”, “Name Based” and “Call Sign Based”.

Note that what you see on the display of the 878 is configurable. The DMR-ID is part of the transmission and the radio uses the “digital contact list” to turn the “Radio-ID” into what you see on the display. I still have a few more bookmarked to watch but I am getting a handle on it.What you see on the display is a function of what is in your radio. I used many web resources along with several YouTube videos. Overall the process was not difficult, but took some time researching how DMR worked so I could understand the programming better. I am planning on taking the hotspot on business trips and possibly use it in the car for DMR mobile. My next step is to find other talk groups that I might want to listen to, and determine how I will use DMR going forward. I also made a call and confirmed that I was able to transmit on the talk group as well as receive. I listen to the Hamradio 360 Workbench podcast and they use a talk group that I programmed into a channel and was able to hear some of that traffic. I won’t go into a lot of detail on programming the radio as there are a lot of YouTube videos and web pages describing that process. After consulting the band plans and looking at the Arkansas repeater council page, I was able to choose one to use. I had to choose a simplex 70cm frequency. The next step was to program the TYT MD-380. It was worth browsing around and finding information that I didn’t know.Īfter configuring the hotspot, I was able to verify that it connected to the BrandMeister Network.

There is a lot of information on this site in addition to this page related to DMR. To setup the Pi-Star software, I followed along with this page:

DMR JOTSPOT UPGRADE

pistar-update / pistar-upgrade which are similar to the Raspian apt-get-update and apt-get upgrade commands but do so for the operating system and the software included in pi-star. The Pi-Star creators provide two commands for doing that. The second important thing to do is to make sure the image is updated. When first written, a small portion of the space is used and a command needs to be run to expand the file system to use the rest of the space. The first is to expand the image to use the entire card. Pi-Star can be downloaded from here. Once the image was downloaded, I used the Linux dd command to write the image to the card.Īfter inserting the card into the Pi and booting it up, there are two very important steps. It is an easy way to get everything you need for DMR, DStar, P25 and more digital voice modes. It is essentially Raspian with MMDVMHost, DStarRepeater and other software included.

DMR JOTSPOT INSTALL

One could download Raspian and install all the software separately but there is an image already created that is very popular called Pi-Star. One of these cards is less than $15, so it is not very expensive compared to the cost of the entire hotspot project. It is important to use a decent storage card so the performance isn’t worse than it needs to be. I don’t know that I need them so I left them out.įor storage for the Pi, I used a Sandisk class 10 32GB micro SD card that I already had. The completed Pi, DVMega combination put together and ready to go. I asked a friend with a 3D printer to print this case for the Pi and DVMega from Thingiverse. I figured putting together my own hotspot would be the ticket as I have three Raspberry Pi’s sitting around doing nothing but collecting dust, so acting on some advice from more experienced hams, I ordered a DVMega board to go with one of the Pi’s.

DMR JOTSPOT CODE

I wanted to start simple and begin my code plug from scratch. The closest DMR repeater to my house is about 20 miles away and with all the hills around Arkansas, I cannot hear it with the HT antenna.

DMR JOTSPOT HOW TO

I decided to take a step back and learn some more about how DMR works and how to do the programming. It was a lot to digest for someone who didn’t know how to program a DMR radio. He had all the repeaters for two states, lots of talk groups and lots of operator call signs. This friend sent me his code plug and when I looked at it I was lost. After that, I decided to order the same radio and see what DMR was all about. He uses it a lot when he travels around a two state are for his job and loves it. If you are a seasoned DMR operator, then you likely know all this already.Ī friend of mine brought an inexpensive TYT MD-380 DMR radio to a club meeting and told us about DMR. As with most of my posts, this is aimed at someone just looking at and thinking about diving into DMR. This post is going to be about my learning and stepping in DMR. Ham Radio, as you all know, is a diverse hobby with a lot of different ways to enjoy it. There is a lot of blogs, forums and place to get information about various aspects of our hobby.
