All 3 of those TSBKs have a MFID of 0x00 (2nd byte), therefore they should be standard
Per the spreadsheet (assuming OSP):
0x30 - b0 00 00 04 00 00 00 00 33 20 00 00 - SYNC_BCST (Synchronization Broadcast)
0x38 - b8 00 08 0c 2e 00 0c 2e 00 01 00 00 - SYS_SRV_BCST (System Service Broadcast)
0x14 - 94 00 00 01 65 ff ff 31 25 d7 00 00 - SN-DATA_CHN_GNT (SNDCP Data Channel Grant)

Matt,
Thank you for the information (and Ellie). Hopefully someone can help with the $14 code.
I do know that when the system was installed here, pretty much it was left to the
consultants. So I don’t think I can dig it up locally.

Ok, it shouldn't be too hard to update OP25 to support TSBK opcodes $30 and $38, but
$14 is still a mystery... Please see the attached spreadsheet for a list of opcodes that
we currently know about. If you have any info on any of the manufacturer specific opcodes,
please feel free to let us know.
0x30 is a Harris Dynamic regrouping command:-

0x38 is a standard authentication response:-

I'll see how we can go about getting these added in. I'm not sure what the best
approach would be to reduce noise in the logs however - any ideas Max?
Credit for the attached spreadsheet goes to Ellie Dugger (thnx Ellie!)
Cheers,
Matt

Hi Kevin,
Is this by chance a Harris system that you are monitoring?
Cheers,

Minor request.
It multi_rx.py it is difficult to find other issues because of messages regarding
unsupported TSBK opcodes. It isn't hurting but just filling the log. Not sure how
best to report these (increase the log level?).
Examples in my case are as below:
received unsupported TSBK opcode 30 (b00000040000000033200000)
received unsupported TSBK opcode 38 (b800080c2e000c2e00010000)
received unsupported TSBK opcode 14 (9400000165ffff3125d70000)
I understand the need to know about these but it isn't helpful to have the log filling
up with these.
Kevin
