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

https://brandmeister.network/?page=news&post=9
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!

Breakfast Time again – August 26th 2017

Hello from your host’s Dave – KE0NA and John KA0KMJ

It’s been another two weeks, so it’s time to get together at Fat Nat’s Eggs in St. Anthony Village for DMR breakfast!

Enjoy some delicious food, get your DMR questions answered, arrange to have a code plug loaded onto your radio.

It’s the best way to catch up on the dynamic world of DMR in Minnesota while socializing with a friendly group of guys and gals.

The earlier birds will be there at 7:30 AM (or even earlier) but the official start time is 8:00 AM.

Next breakfast will be August 12th 2017.

Hello All,

Free admission for buyers. Sellers pay $5.00 which will be donated to the Church. Please bring your own table and chairs.  Talk in on 145.170. 100.0 tone or DMR MNStatewide(3127) – Give a holler for K0GOI or 444.050 PL 114.8Hz

See you there.  You may have a chance to play with the new TYT MD-2017 dual-band DMR radio. Terry plans to have one on display.

Maximum Coverage from DMR systems

So recently heard on the air was a discussion about working DMR systems from an airplane; During that talk, there was a claim the repeater was able to be worked with a full bi-directional conversation from a couple hundred miles away.

I was really surprised. I’m fairly sure reception is possible over tremendous distances, but you would be unable to hold the proper time-slot with a TDMA network like Tera and DMR.

Here’s a discussion I found online: http://forum.motorola-radio-support.co.uk/index.php?topic=1035.0  And here’s an FAQ from Tait: http://blog.taitradio.com/2013/09/26/dmr-digital-mobile-radio-frequently-asked-questions/  and: http://owenduffy.net/blog/?p=9133  and: http://www.va3xpr.net/search-range-limit-dmr/

I thought I’d toss this out there to see what others may know or think about this?

I wondered if maybe its possible but you risk stomping on the other time-slot had there been two time-slots in use towards the repeater?

I’m quite certain that with DMO mode aka a Simplex radio connection where there is no need for syncing or precise timing, there would be no problem. This impacts only repeater operation where both time-slots are in use.

For anyone wanting to claim D-Star and Fusion are better than DMR, this might be one example of where they may be. But I’m happy with DMR and it’s ability to carry two conversations from one pair and it’s lower power consumption. The world is full of trade offs.
