document what happens if recorders are not specified

Open ZeroChaos- opened this issue 3 years ago • 3 comments

The docs indicate that analogRecorders and digitalRecorders are optional keys, but what happens when they aren't specified isn't documented. Please update the documentation to include what happens if these keys are not specified.

based on some conversations in gitter, I think in general this section of the docs could use more information. Specifically "what should these be set to and why" would be helpful. Things like "what happens if I specify 10 recorders and 5 channels" and "what happens if I specify 5 recorders and 10 channels" would make excellent examples to elucidate what these values do.

Agreed - let me go build out the config doc a bit more: https://github.com/robotastic/trunk-recorder/blob/master/docs/CONFIGURE.md

It doesn't really cover different strategies... will also expand upon this comment from gitter:

If you are trying to only record conventional channels, you do not need to specify analogRecorders or digitalRecorders for a source. When you add a conventional channel, it gets a dedicated recorder assigned to it. The reason it chews up CPU is that it is constantly channelizing the IQ coming in and check to see if it breaks squelch. Using a smaller Source bandwidth means it is easier to do that channelization.

I know this is late, but there are cases where 0 recorders would be desired, such as testing or where you're only interested in the control channel messages
