BIAS-T option

[ExquisiteMetropolis]

I've tested your container via this Home-Assistant add-on:
https://community.home-assistant.io/t/home-assistant-add-on-ads-b-multi-portal-feeder-flightradar24-and-flightaware/345563
Where I previously used a few docker containers: https://github.com/sdr-enthusiasts/docker-readsb-protobuf/pkgs/container/docker-readsb-protobuf (Sorry not yours...)

Following a power cycle, I noticed that since I switched to the HA-addon my reception range dropped.
Quick study showed my LNA filter wasn't powered anymore. Reason: BIAS-T wasn't switched on anymore.
The readsb container has a switch for that, the HA-addon (and your container?) doesn't as far as I have been able to determine.
Besides that, it provides for a lot of tuning options of the signal as well.

Reverting to the separate containers fixed the issue, BIAS-T was switched back on (needs to be done after each power cycle, it's not possible to fix this within the firmware/hardware of the RTL-SDR dongle), my reception range was back to normal.
Also via the HA-addin that uses your containers.

Reseating the RTLSDR dongle into the USB port resulted in the same. Less range, until the readsb container was restarted and switched on BIAS-T in the dongle.

Would it be possible to (at least) enable BIAS-T in yours? And preferably the other tuning options as well?

My goal is to stop using seperate docker containers and switch from HA supervised, to full HA OS.
