Multiple static talk groups not working with OpenSpot

I have entered multiple static talk groups (maybe 10 or so) for one of my OpenSpots and entered them all into a receive list on my radio so that I can use one of my OpenSpots and that radio to "scan" for activity on those talk groups (I use a separate OpenSpot and radio for QSOs once activity is identified). However, I have found that only one talk group at a time seems to be static, even once activity ceases--e.g., I enter 310 and 3100 as static talk groups; activity commences on 3100; once activity ceases on 3100 and activity thereafter starts on 310, I hear nothing on 310 until I key up on 310. If I do key up on 310, I hear any activity on 310, but thereafter seem not to hear activity on 3100, even after activity ceases on 310. Any help would be appreciated.

I have created a video on how to set up static TG s on BrandMeister using the OpenSpot .

Once I had them set up - for several weeks - I suffered the same ill effect of not having the OpenSpot switch from one TG to another one .

At first, I thought it was a problem with the OpenSpot . Then I found out that the problem is with the United States servers . Once I changed my OS to use the Canadian server, I see that it works just fine .

Hello! Can you specify how you are "entering multiple static talk groups" ? Are you setting them up in your selfcare and/or the OpenSpot ? Please send some screenshots if you can (you can use for example, just PrintScreen and mltiple Ctrl-V directly in imgur). Thanks!

Yes--thanks. I am using self care to set them up. I realize that using my radio I can effectively set up a single temporary static talk group (the first one after sending a TG 4000 signal). I will try to paste a screenshot below.

The SharkRF openspot only supports one active static talkgroup at a time. Entering multiple ones won't do anything-it will default to "locking onto" which ever one you last used.

It is designed that way so if you are having a conversation on talkgroup A, then talkgroup B won't interfere with your QSO. If you have two static talk groups, it would be "First come first served" and if there was a conversation on both, you'd likely hear them both back and forth while you were trying to conduct a QSO on one of them.

You will have to pick one or the other, or switch between them as you wish to use either, or have a second openspot to accomplish what you are trying to do, and even then, it would be one per OpenSpot.

I tried this myself when I first got it then realized that it wouldn't work right by doing so if you got one or more talkgroups active at once and were trying to have a QSO.

It would also cause you to have to potentially use ten times the bandwith to accomplish what you are wanting to do. If every OpenSpot user did that, that would be a major cost for Brandmeister as well, which is another reason why it is not supported. Only one stream per time will be sent to it (plus non-statics for 30 minutes) but only one stream at a time will ever come to it, and then to your radio.

To be more specific, there is no limitation of static talkgroups with the openspot. The device behaves just like a repeater and transmits what it receives from the DMR server. So if the server considers there are multiple static TG, it will route traffic from these TG and hold-off timer applies.

Thanks--That is interesting. My plan was to use one hotspot as sort of a scanner--set up multiple static talk groups and than a large receive group (or TYT tools and promiscuous mode) to scan for activity. I wold then use a separate radio and a separate openspot for QSOs. That way I wold not have
