DMR - no received audio

Post by Phil VK4IIO » Sun Mar 24, 2019 10:10 am

Hi group,

I have the OpenSpot 2 configured for both D-Star and DMR in Australia.

When using DMR I an unable to monitor a Talk Group, no audio, without first keying up my handheld. I know some TG's and repeaters require a user to key up first to trigger the link, however when I operate a local repeater using the same TG the audio is always relayed.

Is there any settings I need to make on the dongle, or is it a feature of the Radio (MD-380) or a restriction of DMR itself?

Any help would be appreciated. Thanks in advance...

The talkgroups that you can hear without keying up on a repeater are the ones that the repeater operator has set as static. All other talkgroups required keying up to actavate and are called dynamic and stay active for 15 min after the last time you key it.

Essentially the talk groups on the Openspot 2 are dynamic to start. You have to key them up with your radio or with the web interface to hear them. It is a little more complicated than that but that should get you going in the right direction. For instance there are ways to set talkgroups as static on the Openspot 2.

You perhaps need to read the online manual.

Hi Hank, Norbert,

I appreciate you taking the time to reply to my post.

I guess there is a big difference between reading and understanding.. A a new user I have found the concepts of DMR in it's many forms a challenge, that said I am making progress with help from people like yourselves.

I will configure as documented and test further.

Thanks again,

Phil

In short: you need to have a talkgroup linked in order to hear it. The BrandMeister Network has a feature called auto static talkgroups, which makes using talkgroups much easier with hotspots. You can find more about auto static talkgroups on the user manual page I've linked.

The openSPOT2's default frequency is 433.900 MHz. Set up your radio's RX and TX frequencies for that. Make sure you link the talkgroup you want to hear.

Create a Receive Group List and add TG9 to that list. Then attach the group list to all channels used with the openspot.
