While you can dynamically add tgids to either the blacklist or whitelist, these are not persistent across restarts because boatbod op25 does not (yet) write config files. If you desire persistent bl/wl you need to create a text file and add it to the appropriate trunk.tsv (or cfg.json) entry. File format is one line per tgid, decimal tgid value only. Optionally you can specify ranges of tgid by making the entry two columns (start-tgid / end-tgid) with the usual tab separator.

Doing some trial-and-error, here's what I think I've figured out so far. Right or wrong?

What the buttons do:

SKIP This is not a lockout. It is basically like a scan button on a traditional scanner where you tell OP25 to get off the current TG and search on to the next one.

HOLD This holds on whatever the current TG is that you’re on.

GOTO This gives you a pop-up box that lets you type a TGID that you wanna listen to. Then it will hold on that TG.

B/LIST Blacklist, this is a temporary lockout. The TG will no longer be stopped on during your current session. After you close OP25 and re-start it again, any TGs you blacklisted (temporarily locked out) are restored and will be stopped on. You must click the B/LIST during an actual voice call, not during the scan/search hold time. Otherwise, you’ll get a pop-up box asking what TGID to blacklist.

W/LIST Whitelist, always gives you a pop-up box to enter the TGID. If you whitelist even just 1 TG, OP25 will only stop for that one TG. All other TGs will be ignored. This is temporary until the next time you run OP25, after which the TGs are no longer whitelisted and OP25 will stop on whatever it finds.

So how dose the LOG button work? It asks you to "Enter logging level". What range of numbers can we type in and what does each number do? Does it create a file somewhere? Where does it save it and what is the file name?

LOG allows you to dynamically change the log level. It takes an integer from 0 thru 11, with 0 being the least verbose and 11 being the most. Generally 1 works well for normal monitoring, 5 if you want to see tgid activity, 9 for xMBE codewords, 10 for protocol messages and 11 for trunking internals.

The log itself is written to stderr.2 or wherever you redirect that when you start rx.py/multi_rx.py
