UoM University of Minnesota DMR site is deferring the move to Brandmeister. Mother nature takes control.

Matt, NØYNT had planned to move his repeater over to Brandmeister but discovered the weather has taken control and the door lock was frozen making the site inaccessible. A future date will depend on weather cooperation. Galen as already updated the codeplug so new code-plugs will not work for Nationwide and Worldwide talk-groups on this one repeater.

Matt may need to fight back with lock-deicer… More news as it develops.

Centerville Repeater moved to Brandmeister Network

Terry’s repeater in Centerville was moved from the K4USD cBridge over to Brandmeister about 4pm this past Saturday the 31st. Minnesota State TG3127 is on Time-Slot 1.

Updated code-plugs (Radio Programming) are available for download on this website.

The move includes a couple of minor changes for talk-group numbers. The Old TG1 becomes 91, the Old 3 becomes 93.  MNDMR is now available at TG31127.

More repeaters swapping Minnesota Statewide and MNDMR Time-slots

Bill – KDØYRF has announced that on Wednesday evening after the Wednesday night net, January 10th, Repeaters connected to the MNDMR cBridge will be reconfigured to modify or swap the time-slots for two talk-groups. Minnesota Statewide TG3127 will be moving from Time-Slot 2 to Time-Slot 1 just like the MTKA, BLM, BLW, Chaska and StPaul repeaters. They will then move their MNDMR TG31127(1127) from Time-Slot 1 over to 2.

The impacted repeaters are AIR, MSP, LIT, BKH, MED, RST.

The move for Minnesota Statewide from TS2 to TS1 accomplishes the goal of freeing up Time-Slot 2 for more user activated activities including Local2, Local9 and the TAC talk-groups. Today Minnesota Statewide is where most of the activity is. If it’s active, these other talk-groups are impacted and basically unavailable.

Please plan for updating your code-plug (Radio programming) on Wednesday night after the net or around 8pm January 10th. New updated code-plugs can be found on this site around that date.

MMDVM Hotspot with OLED display

For anyone handy with a soldering iron, here’s some eye candy. It’s not that difficult to add an OLED display to the MMDVM hotspots if you have a steady hand, good eyesight and about 10 bucks. I’m recommending the Pi-Star software distribution for our MMDVM hotspots as most all of the configuration is now possible from a web browser and the software for running external displays is built in (always could be enabled, but it’s easier now) OLED display can be sourced from China for about 4 bucks and 4 weeks… Amazon will bring you one tomorrow if you like: https://www.amazon.com/gp/product/B01AE3MR7Q/ I plan to polish my plastic case with one of those headlight rejuvenation kits. Should become crystal clear with a small amount of elbow grease.


Another teaser – New hardware pledge

If you’re a digital radio nerd, you might be interested in the sexy, ham sexy, new hardware under development. I am one of the early pledges to see this hardware come to fruition. You can check out the device here: http://kck.st/2jUfo1z

This little USB dongle will support the bidirectional trans-coding of our digital streams from one radio technology to another. So, someday in the not too distant future, you might be able to turn on your DMR radio and bridge to another radio frequency in a another part of the state or world. Let’s say you’re on vacation and in Hawaii. Imagine turning your radio dial to a DMR talk-group where you can control a remote base in Minneapolis and entering the 146.XX repeater into the DTMF pad on the front of your radio. That ability to encode and decode the analog stream into the DMR network is provided by this hardware. There’s still software in development and the same is true with this hardware. It’s not here today, but there are those of us behind the scene working on these technical challenges. DStar, Fusion, Analog, DMR, P25, Other IMBE are all modes being worked on.

I’d like to ask for your financial support. Installing and operating the DMR network isn’t inexpensive. The repeaters themselves begin to look really cheap when you consider the filtering, cabling, duplexers, electric bills, hard-line, connectors, lightening protection, Internet access, routers, microwave links, etc. With your financial support, I can continue to invest in new technologies and increase the capabilities of Minnesota’s DMR (and other) Radio Networks. The KickStarter project will be funded at the end of January. I hope to have ~$400 for this hardware dongle and will contribute testing and code review to the projects. Additional projects include the WhiteBear Township Water Tower DMR site, Duluth Hill DMR site and with the right funding, a major DMR installation in the eastern metro. Unfortunately both WhiteBear and eastern metro have hellacious installation expenses. Paypal donations gladly accepted at ejosterberg@gmail.com – 73 nØnki – Eric Osterberg I’d like to thank those of you who have already donated for past projects and without any solicitation. I very much appreciate this.

Happy Birthday Brandmeister

Two years ago today, Brandmeister appeared at the domain: brandmeister.network

The network designed by hams for hams using completely open specifications designed to connect anything without regard for the politics.
Without Brandmeister, your hotspot would not exist. Home brew equipment would not have access to the networks. (Or maybe someone else would have done it!) I’m very thankful myself. Happy belated Thanks-Giving day!
