Adaptive Duty Cycle does not work as expected

[by]

I'm running the current version 9.0~dev from github on a Raspberry Pi with bookworm 64-bit.

Experimentally, I've tried to set ADAPTIVE_DUTY_CYCLE=100 in /etc/default/dump1090-fa but systemctl status dump1090-fa only reports adaptive: using 50% duty cycle

[mutability]

ADAPTIVE_DUTY_CYCLE=100

There is no such config setting (see start-dump1090-fa for the settings it knows about).

If you want to tune this you'll need to put --adaptive-duty-cycle in EXTRA_OPTIONS

Thank you!
