Most of my experiments have been with timeslot 1.

I have a “disconnect” channel for both time slots 1 and 2.

Okay -- we're past my theoretical knowledge...

Thanks for trying.

If I don’t get any more suggestions here, I might try posting again under the general help topic.

Is this even a thing ???
How could this work ???

If ts2 is busy, how would keying ts1 with an unlink call tg4000 drop ts2. It'll just drop whatevers connected on ts1.

I dont know where you heard this but, i can't see how that could work.

You are right, that won’t work, but that isn’t what I am trying to do.

I am trying to disconnect TS 1 while it is busy by sending a 4000 to TS 1. This is not working.

(Same for TS 2 - a call to 4000 on TS 2)

You cannot issue a disconnect while the hotspot is in an active situation. The hotspot must be idle for you to be able to issue a disconnect and have it acted on. As long as there is traffic it will not work.

My understanding of the concept (remember, /I/ don't have a duplex system myself) was that, with two frequencies in use, the hotspot can receive on the input frequency even while sending on the output frequency. But perhaps that requires full "repeater" configuration -- with separate external receive/transmit radios (though I thought duplex units had two flea-power radio modules on-board).

After all, it has to be possible on a true repeater, or there would be no way for a local user to disconnect a "locked" (someone elsewhere with a constant PTT) talk group.

OTOH: since duplex hotspots are, to my knowledge, treated as repeaters (by Brandmeister at least), all talk groups are dynamic, and will time out after something like 10-15 minutes so long as the local side doesn't transmit to it.

Thanks for the report. I’m starting to accept that it isn’t possible with the duplex hotspots.

It works fine on my local repeater and I thought a duplex hotspot would work the same.

Maybe it is something that can be fixed in software, but that is probably an MMDVM thing, not PiStar.

I think the best way to do what you want and drop a QSO is to use the admin control panel with your BM API key installed instead of a radio.

Ok, I obvs. misunderstood what you were trying to do. Now i know, Im still not aware of this as a feature of a hotspot board. If it's txing traffic, it can't get that drop request back to the server.

I think that there are quite a few changes in the HAT firmware since the 1.4.17 release, and indeed since the 1.5.1 beta, that relate to duplex hotspots.

I am not sure when Andy is planning to release the 1.5.x firmware, maybe the other Andy(s) know(s).
