Talker Alias on BrandMeister

Talker Alias allows a radio to receive contact information from the transmitting radio. Much like D-STAR and Fusion, this removes the need to have a large contact list. Additionally, BrandMeister helps the process by creating a Talker Alias string if the transmitting radio doesn’t send one.

Talker Alias was added to the DMR ETSI spec in June 2016. To date, the only radios to support Talker Alias are Hytera and the MD Tools software (MD-380, MD-390, and maybe the MD-2017). Additionally, Talker Alias is only passed through Hytera repeaters, MMDVM-based repeaters and most hotspot devices (OpenSpot, MMDVM/Pi-Star, etc).

With those limitations in mind, this is still a great feature. Hytera and TYT covers a large chunk of DMR users worldwide.

BrandMeister as included the ability for you to modify the text sent via Talker Alias, this is done through the Selfcare page using the APRS Text field. BrandMeister always adds your call sign in front of the APRS Text field.

In the last heard list you can see which users have set this text and which have not. The default value is “DMR ID:3106xxx”.

Here is an example of some people with APRS Text, and some without. I’m not trying to call anyone out here, just providing an example.

For the benefit of those using Talker Alias, please modify your APRS Text to have your name. This also gives you some control over how your name is shown…

    Hi Michael,
    I was told that the Talker Alias function causes problems with Motorola repeaters.
    Specifically, enabling the Talker Alias in Hytera radio (radio to send the Talker Alias data via a Repeater) causes distorted or lost audio on Motorola repeaters.

    Have you heard of this?

    And is there any benefit in turning on the Talker Alias already in your radio if you can “tag on” the same data at the Brandmeister level?
    I.e. If I set the “APRS Text” in my Brandmeister Self Care, would there be any reason to enable the Talker Alias in my Hytera codeplug?

    Thanks!

      Yes, Talker Alias can cause problems on Motorola repeaters. I’ve had a couple of people tell me they think this is because Motorola used those bits for something else. But, I don’t know that for a fact.

      The APRS Text is what BrandMeister will send to Talker Alias compatible repeaters (Hytera and MMDVM) if the transmitting radio doesn’t send anything.
