Talker Alias on BrandMeister

Bron: mrickey.com

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…

D-Star ONE Phoenix, Eerste D-Star Communication Spacecraft, gelanceerd

A Soyuz rocket launched D-Star ONE Phoenix and 10 other satellites into orbit on February 1 from Vostochny Cosmodrome in Russia. Developed by German Orbital Systems in Berlin in cooperation with the Czech company iSky Technology, D-Star ONE Phoenix carries an Amateur Radio relay payload (call sign DP1GOS). It replaces the D-Star ONE nanosatellite that failed to attain orbit following a November Soyuz launch from Vostochny.

Downlink frequencies are 435.700 MHz for telemetry and 435.525 MHz for D-Star. The uplink is 437.325 MHz.

D-Star ONE Phoenix is a 3U CubeSat equipped with four identical radio modules with D-Star capability, operating in half-duplex mode with a power output of 800 mW. The two telemetry and telecommand modules both receive, and both in sequence, so each telemetry frame is repeated. The other two modules are dedicated to Amateur Radio, although only one will operate at a time.

The modules are configured to work as D-Star repeaters, so they retransmit received D-Star frames on the downlink frequency. They also have a D-Star voice beacon. — Thanks to AMSAT News Service, D-Star ONE
