How does DMR APRS work on the Ailunce HD1

How does DMR APRS work on the Ailunce HD1

Finally Ailunce released a firmware added DMR APRS on HD1. 

How does DMR APRS works?

The DMR radio (GPS version) sends an SMS message with GPS information to the MMDVM hotspot board -> mmdvm receives the data packet and forwards it to the BrandMeister (BM) server via the network -> the BM server forwards the GPS message packet to aprs.fi, thus Enables real-time viewing of positioning and movement trajectories on the aprs.fi website.

What do you need to get HD1 GPS position on aprs.fi?

  1. Dual band Ailunce HD1 radio. 

  2. MMDVM DMR Hotspot. 

  3. DMR Callsign and ID is needed. 

   4. Update your HD1 firmware to version 1.60.   (Please follow this blog  https://www.ailunce.com/blog/upgrade-hd1-firmware  to do correct firmware update operation).

   5. Download HD1 software

Setting-up-DMR-APRS-on-Ailunce-HD1-DMR-Radio

a. Set your DMR Callsign and ID.

b. Create a Private call for APRS, ID is 460999. this is dependings on which BM server you use. ID xxx999 is the Brandmesiter gataway to APRS, where xxx is your nearest country master server (204 for the Netherlands,222 for Italy, 206 for Belgium,etc)

c. Create APRS channel, frequency is same or reversal of your DMR hotspot frequency. Low power. Enable GPS in the channel setting.  

d. Create other channel which you like standby on it. like TG91, TG3100, etc.  Then creact a RX group list.  Add this Rx group list to APRS channel.  then when radio is on APRS channel, you can also listening on TG91 or TG3100.

Press PTT will send GPS position information to BM Master. then take your Hotspot and HD1 together go around. It will report position information based on your GPS interval time.

Visit https://aprs.fi/   Search your APRS callsign. You can see the positioning and trajectory. 

If switch to other channel without GPS, it will stop APRS information transmission.

Hi, is it possible at all to make this feature work with Hytera RD985? For me it works perfectly with my mmdvm hotspot but not when I am on the Hytera repeater. I hear that this is a "known issue" with Ailunce HD1 which cannot send SMS nor APRS over Hytera, do you confirm?

Hi, This works fine as long as I use my hotspot. But when I try the same through my local repeater, it does not work. My repeater is OZ0KAR and is a Hytera repeater. I saw a comment on your youtube video about this subject that someone else also did not succeed in using APRS over his repeater.

I have it working on the HD1, took a bit of work to configure, really happy. Was having some issue with wrong id being used for aprs, because I have 2 Host spots running D-Star, but that is down to me understanding how the radios channel A and B works and nothing to do with APRS. Look forward to refining the configuration as I go. 73 Ron ZL3RCK-7

Can HD1 GPS work with APRS using DMR repeater? Or i need allways hotspot?

Yes, There's no difference between Hotspot or repeater regarding Aprs. You have to make a private contact with ID xxx999, where xxx are the first 3 digits of your Brandmeister Master (country-code).

could the alliunce hd1 in future fw versions send automatically aprs position like rt3 and rt8?

What do you mean with "You have to make a private contact with ID xxx999, where xxx are the first 3 digits of your Brandmeister Master (country-code)" - Does it mean GPS position is only transmitted when I push PTT after having configured a private call to xxx999?

Yes, you are correct. for every BM master, it has a unique APRS private ID.

It has nothing to do with GPS, You can search the country-code on Brandmeister.
