See PR #26 for my new attempt at adding squelch - this adds a standalone squelch utility which currently does CSQ, and in the future could do CTCSS and DCS.

I've been trying to build the latest master on an MSYS2 install for my windows machine. I've configured the config.mk file to properly point to my /mingw64 folder, and it...

A little more testing - the heart of the issue is AGC being forced on - `IFGR` can't be set when it's enabled. According to https://github.com/robotastic/trunk-recorder/issues/422#issuecomment-961987028 AGC must be first...

This is also preventing me from decoding the system I'm tracking. Control channel is decoding fine, but all audio calls are heavily garbled with lots of errors which I'm guessing...

Sorry for abandoning this issue - life has been busy. You guys are correct - I added lines in the code to toggle AGC on startup and that seems to...

Here's the associated JSON for one of those calls: ```json { "freq": 856937500, "start_time": 1650026369, "stop_time": 1650026378, "emergency": 0, "encrypted": 0, "call_length": 9, "talkgroup": 10106, "talkgroup_tag": "IMPD NO1", "talkgroup_description": "North...

I don't have any `callTimeout` specified so it should be using whatever is the default value. I've also noticed occasionally certain transmissions will be extremely quiet - even ones from...

Sorry, I meant the audio normalization routine. Here's my sanitized config: ```json { "ver": 2, "sources": [{ "center": 856125000, "rate": 2560000, "error": -200, "gain": 30, "digitalRecorders": 8, "driver": "osmosdr", "device":...

Wondering if there's anything else I can try to reduce this issue. It's very jarring to be listening to the scanner and have a loud burst of noise come across.

Do you know where the normalization occurs in the code? I might look into adding some kind of audio threshold check that skips normalization on silent calls.
