Talker Alias in firmware MD380

Link naar nieuwe firmware met TA hier!

Het zaadje is gepland. Nu TA werkt op Hytera apparatuur is het ook gelukt de TA mee te zenden naar de MD380 via BrandMeister! Er dient echter nu nog een oplossing gevonden te worden om de TA ook weer te geven op het display van de MD380.

Foundation for Talker Alias in MD-380 radios laid

Something about laid and fertilized, but not yet hatched eggs. So why bother talking about those? Well, maybe some coders want to help finishing an user interface for this.

The BrandMeister coding team decided helping improve the MD-380 firmware enhancement of Travis Goodspeed (https://github.com/travisgoodspeed/md380tools). With the latest commit the radio is aware of the Talker Alias and shovels it through its log file, so
that it can already be read over USB from a PC. Now the job is implementing a display routine in the radio firmware.

Volunteers, go for the race for the best implementation. Now! 🙂
BrandMeister is the community driven network!

Nieuwe TA feature BrandMeister


BrandMeister heeft gisteren een feature toegevoegd met als doel de TA (Talker Alias), een optie in Hytera apparatuur, beter te laten verlopen. TA is een optie die behoort bij de nieuwe DMR ETSI standaar en is door Hytera geïmplementeerd in hun apparatuur Het is nu voor iedereen mogelijk een TA in te stellen via de selfcare webpagina van Brandmeister. Deze APRS tekst wordt dan meegezonden met de data en kan op de ontvangende set worden weergegeven. Via Motorola repeaters werkt deze optie “nog” niet maar er zal ook geen verstoring optreden als de feature toch wordt aangezet. Met dank aan het BrandMeister coding team. Alle informatie over de veranderingen aan BrandMeister vind je in het changelog hier! De Nederlandse codepluggen zijn reeds voorbereid op de optie! In de toekomst zou het overnemen van de roepnamen in de codepluggen overbodig worden. Nu reeds moet een selectie gemaakt worden van de meest gebruikte roepnamen omdat het aantal geheugenplaatsen in een radio soms beperkt is.

Bouw je eigen MMDVM hotspot voor minder dan $100USD

Bron: mmdvm.blogspot.com
I’m pleased to announce a big step forward for the open source MMDVM project. There is now support for the ADF7021 RF chip. A lot of work has been going on in the background. A special shout out needs to go to Andy CA6JAU. Without his countless hours of work this would remain a half finished project still sitting on my workbench.

This means mmdvmhost/mmdvm can now talk directly to the 7021 chip so external radios are not needed. In the initial release of source code, there is support for DStar, DMR (DMO), Fusion and P25. Fusion and P25 have not had any significant amount of testing done.
Now to the good stuff. All the source code is currently hosted on Andy’s github.
We will be working on getting it merged into the mainline code.
I also posted in the Files section a document with build and installation instructions.
The hardware used during development is a combination of an ADF7021 board and an STM32F103 board. To make it easier to put the parts together I designed a simple carrier board (see attached picture). Everything is thru-hole so most everyone should be able to solder it. As soon as the Chinese New Year break is over, Bruce will be ordering more blank boards.
The stock ADF7021 board needs two modifications. The first is the oscillator has to be replaced with a low ppm TCXO. The second mod is a jumper needed to connect a pin on the 7021 chip to the NC pin on the ADF7021 board header. More pictures will be coming shortly.
The ADF7021 boards are no longer being manufactured. Through his connections in China Bruce has acquired a small number of them and is currently having the two modifications done.  His supplier claims to still have some remaining stock. If there is enough interest from the group I’m sure he can try to get more.

If you are interested in helping to test, PM Bruce. He will be in touch with updates on kit availability. We’d like to give priority to those who are more comfortable with the ins and outs of setting up the build environment and able to do the soldering.
