Scanning / Promiscuous with a hotspot ? Newbie

Post by M7MLB »

Probably a daft newbie question..

But when using Pi-Star hotspot (DMR). Is it only ever able to listen to 1 talkgroup at a time? In respect if i set my radio (MD380) to either scan or Promiscuous mode, am i right in thinking it will have no effect as radio can only here the 1 channel the hotspot is broadcasting?

Only just getting setup, and would like to be able to monitor a pile of talkgroups to see which ones are busiest for me. But getting confused as to if scan/promiscuous works when im using a home hotspot?

Ive also found if i manually kerchunk my radio to say TG81, in dashboard it changes to TG81 ok. But after a few minutes dashboard shows TG9 again and i miss users on TG81. ?

Thanks

What DMR host are you using?

For example -- I don't have any channels configured for TG 9 as Brandmeister US doesn't use Reflectors. I have two talk groups configured as static (in theory, any traffic on those groups should be passed through -- but since they are the MI5 Statewide and MI5 is not formally a BM repeater network it may be that the link only goes active if someone on BM activates the talk group first). The other talk groups I have set up as Dynamic on BM. For BM /hotspots/, the last activated dynamic talk groups becomes pseudo-static -- it does not expire. Any other dynamic talk group that has been activated will expire after about 15 minutes. For BM /repeaters/, all talk groups expire after 15 minutes if no one has PTT on them.

Oh, and just FYI... If multiple dynamic talk groups are active on BM, then having the radio channel configured with a Receive Group List will allow one to hear all such traffic (one would have to dial in the proper channel to respond -- unless one's radio has a direct-reply feature that automatically uses the talk group of the last reception [until the radio times out -- 2-5 seconds I believe on mine]).
