Question related to the autogain settings #31

Closed matrixxus closed 1 year ago

matrixxus commented 1 year ago

Hello, and sorry for posting this in the issues section, as it's not an error but a question.

It is about: https://github.com/wiedehopf/adsb-scripts/wiki/Automatic-gain-optimization-for-readsb-and-dump1090-fa Thanks for publishing it, works great. My only question is: running your script on a PiAware installation, should I disable the Piaware built-in autogain setting?

RECEIVER_GAIN=43.9
ADAPTIVE_DYNAMIC_RANGE=yes
ADAPTIVE_DYNAMIC_RANGE_TARGET=
ADAPTIVE_BURST=no
ADAPTIVE_MIN_GAIN=
ADAPTIVE_MAX_GAIN=

from the file: /etc/default/dump1090-fa Wondering if this should be changed somehow.

It doesn't work if you install dump1090-fa standalone (without the piaware image).

If you want this autogain, just use my readsb: https://github.com/wiedehopf/adsb-scripts/wiki/Automatic-installation-for-readsb

Thank you very much for the reply. I am on the piaware system image. What I was trying to understand was, if when using your 'autogain-install.sh' script, should the built-in piaware auto-gain option be disabled or enabled. Or doesn't matter at all?

wiedehopf commented 1 year ago

No clue how that interacts, in doubt switch it off. Either script based autogain or their builtin autogain.

Understood, keeping your autogain only, thank you very much for the explanation.
