Hi,

I have been having issues with Teardown appearing in my SDRTrunk instance.

I 'could' potentially be demanding too much from SDRTrunk, however I have had this running previously for 48hrs with no teardowns appearing (about 2 weeks ago). I then took my system away with me for a week, and didn't fire up SDRTrunk for another week. This week I have been having issues consistently.

What I'm trying to do:
I have 4x RTL SDR dongles.
Dongle 1 is monitoring a TIII CC, 160MHz
Dongle 2 is monitoring 2 TIII CCs, 418MHz range
Dongle 3 is monitoring 2 TIII CCs, 463MHz range
Dongle 4 is monitoring a TIII CC, 506MHz range.

It is worth noting that Dongle 2 and 3 are monitoring the same system, just different sites. Duplicate calls are disabled (as there will be quite a few across these sites).

Dongle 1 and 4 have a general 'unknown' talkgroup recoding preference, and 2 and 3 have some TG's programmed in with a general blanket (TG Range 1-max) as unknown as well.

My issue according to the LSN/LCN appears to be coming from Dongle 3, as all the teardown channels have the matching LSN/LCN for that system.

I'm stuck at working out what could be causing these teardown issues (and even if teardown is an issue or can be ignored).

My logs contain lots of entries, however they are all one of these 4 lines

I am recording with Trunking Recorder

Any ideas? Laptop is a moderately spec'd 10th gen i5, 16GB ram.

From the software author on the Google Groups site for SDRTrunk :
"Teardown is the channel state between when the call is ended and either a)the channel gets reset for the next call, or b) the channel gets removed."
Here is a link to the thread: What is Teardown?

Thanks. Explains it a little more. Still dunno why it happens. If I drop all dongles back to 1 control channel each it seems to help. I'll keep an eye on it
