Hotspots are great. You don’t have to worry about who is using it, what talk group it’s on, etc. I have 3 of them, all generic Pi-Star hotspots running ok Raspberry Pi hardware with MMDVM “hats”. If you’re interested in going that route, let me know. I’d be happy to help you out.?

Thanks Jed. My experience is similar to what you described. You need to 'kerchunk' via a quick key-up when you want to change a DMR talk group on a repeater or on a hot spot. This does not cause a transmission to be received by the people monitoring that talk group, but often you can verify the change by either viewing the Brandmeister activity pages, or some repeaters (like SkyHub) have a web dashboard you can access to see if you're registered with the repeater/talk group. The only problem with DMR is that you can only switch talk groups when the channel is idle, which, on a busy talk group, can be tricky and frustrating. On a hot spot you also have the luxury of switching talk groups via the web interface, which does not have that limitation.

By the way, most DMR repeaters will automatically reset to their default talk group after a certain amount of time after being "steered" to an alternate talk group (30 minutes is popular).

A great resource for checking talk group activity is Brandmeister hoseline:??which lets you monitor talkgroups using a web browser. In my experience it's a bit buggy, so your mileage may vary.?
