Some about a picture is worth 1000 words and the video is 7 minutes.  :)

Glenn's comments about the hotspots is about 60 seconds and I linked to where they start.

(For future reference...  if nothing else, I obsess about the use of time, so I would never just point someone to a video and say, "go watch that".  I don't see that as being helpful.  Even if it was a document, if I wasn't in a rush I would direct you to the relevant information or quote it.)

"Promiscuous mode (sometimes called monitor mode) is a radio setting,
not a hotspot setting.  If your radio isn't set to monitor multiple
TGs then it doesn't matter what you do on the hotspot, because even if
the hotspot transmits the audio your radio will squelch it.  In any
case, you can dynamically listen to multiple TGs easily enough, and in
your brandmeister hotspot config you can also set up multiple static
TGs."

Ok, that is a bit clearer.  I'll have to look into that.  That is not my understanding of how dynamic and static talkgroups work- that's a repeater terminology but if there is a way to do put a list of talksgroups in to monitor, I might try doing that so I don't have to switch to different one's manually when I think to do so.

"I won't say that there is no loss.  Sometimes the loss levels can
actually be pretty high, which is probably part of the problem."

Yea, its the loss factor that you don't need much of to be unreadable.  That happens quite a bit on talkgroup 91 with international stations and of course mobile users.  Part of that is operating procedure too.  People don't realize with digital you really do need some lead time so that the communication goes out clean and consistent.

If it is a video, the answer is almost certainly not.  Honestly, I
really prefer stuff I can google or skim, and not 40min videos for
stuff like this.  :)

But, I'll take your word that there are ways to handle it.  If I ever
spend much time listening I might watch the videos.  :)

Promiscuous mode (sometimes called monitor mode) is a radio setting,
not a hotspot setting.  If your radio isn't set to monitor multiple
TGs then it doesn't matter what you do on the hotspot, because even if
the hotspot transmits the audio your radio will squelch it.  In any
case, you can dynamically listen to multiple TGs easily enough, and in
your brandmeister hotspot config you can also set up multiple static
TGs.

No issues sending as far as I'm aware (at least none that I've heard
anybody else complain about), just receiving, and I don't spend a lot
of time listening because honestly most of the time it is hard to
understand much unless I'm listening very actively, and I've seen the
hotspot key up sometimes with the radio just staying squelched.  Could
be an md380tools issue, or maybe an issue with the radio.

I won't say that there is no loss.  Sometimes the loss levels can
actually be pretty high, which is probably part of the problem.
