It will probably end up in a trade, she gets the shoes, I get the antenna 
And no tax exemption, just more to add to the bandwidth consumption but thatās fine no limits here

Some early conclusions on adaptive burst method 2
Adaptive burst mode improves the reception on this specific reciever ( Orange PI, ASBexchange Dongle, FA 5.5 dB antenna)
- A lot less strong messages in this specific reciever, had around 11% , now down to 5%
- Signal varies a lot more with adaptive burst going as low as 24 where in fixed mode it was set to 49.6
- Weakest signal improved from -24 to -38.4 dB
- Range stayed the same.
Iām going to monitor this for a few more days to get some more definitive conclusions, it looks like this is doing better then the fixed gain method.

I am reaching the opposite conclusion for my setup. Fixed gain is seems to be better. Adaptive gain reduces the gain too much during the day.

Well Jim, thatās why Iāll look over some days more. I just want to make sure, reversing it back to fixed is just 2 commands and a simple edit.
Obj said that this isnāt the Holy Grail for setups and that fixed can be better. Since I live close to EHAM and sometimes have them passing within a mile when that approach is opened I figured that adaptive burst might help me in getting a better signal quality. The strong messages reduction is across all receivers Iāve set to adaptive burst but Iām check it in a few days again if this isnāt reducing my stats. If so Iāll revert back

Iām in the direct take-off and landing approaches for a lot of Allegient Airbus A320ās from sunup to sundown and suspect that adaptive burst might have the potential for some positive results here. Thanks for the detailed feedback, Tom. The A320ās are pretty much right over the house!

Yeah, Iām going to wait until the end of the day today (5 PM local time) to see what the Stats page shows. Blue sky day, should be a 3000 plane day.

Hi Jim,
How did you decide for your setup ? Back to fixed or did you leave it on the adaptive burst option?
In my setups Iāve decided for retaining the adaptive burst option.
Reasons why
Reduction of strong messages with 50% on all receivers due to this setting, averaging on 3-5% on the most receivers. I had figures up to 10% on some of them.
Range stays about the same but the number of distant contacts (over 200NM) is better then with fixed gain
Aircraft numbers are slightly up during the last week.
But thereās also some better weather during this week so that isnāt totally up to this change.
@abcd567 thank you for the pointer to your method-2, it stays active on my systems. Even an old goat like me can get things better thanks to your valuable input and experimentation.

Thatās just a wrong conclusion.
Lower gain means the RSSI is lower. And thatās all that youāre observing, lower gain due to adaptive burst.
Not that iām saying one shouldnāt use adaptive burst.
It just means that it lowers gain to ensure close by aircraft are received well.

Thanks for that correction @wiedehopf
I will remove that specific point, that is my wrong interpretation then of the value.
Thanks to programmers of RadarBox24
I discovered the method-2 from Radarbox24ās dump1090-rb, when trying to make Radarbox24ās Non-Configurable dump1090-rb to be Configurable by user.
.
Converting Non-Configurable, Non-Controable dump1090-rb Into Fully User-Configurable, Systemd-Controlled App
Default settings of dump1090-rb
The default settings of dump1090-rb are NOT adjustable by user
The default settings are hard-coded in rbfeeder software, and passed on to dump1090-rb when it is started by rbfeeder.

I say good work on your part for being clever enough to pick up on that adaptive-burst bit and put it all to good practice.

I went back to fixed gain. It seems like it provides slightly better Aircraft Reported on the stats page compared to the adaptive gain option. However thereās not a huge difference one way or the other.
One point ā I donāt see why it makes sense for the adaptive gain algorithm to set the gain way up at night when there are very few planes. (Although I can see why it would do that). It just makes the RPi work harder and consume more power.

Thanks for the feedback Jim.
I really havenāt noticed a increase in power consumption from the Piās since using this option.

Another jumper-inner Iām afraid. Having eagerly read the thread it prompted me to have a fiddle with my gain settings. Iāve gone from what was basically a flat red line to a continuously variable line, hopping up and down all over the place. From various posts it appears this is good but can someone tell me why please.
The settings I changed were based on @abcd567 Method 2 (I think!) and are:
Receiver_gain=49.6
Adaptive_Dynamic_range=yes
Adaptive_burst=yes

Disregard this comment, wrong assumption here 
You should leave the gain at 60 and then let the system handle the ideal setting. Now you are limiting upward (between 49.6 and 60) and then check the results. Best would be to post some screenshot of your graphs1090 so we can see what the system does. Just a few numbers is not enough to draw some conclusions
But as I understand the dynamic gain algorithm, it doesnāt matter where you set the starting gain, the algorithm will adjust the gain to whatever it needs when you set:
ADAPTIVE_DYNAMIC_RANGE=yes
ADAPTIVE_BURST=yes
For example my starting gain was 29.7 dB but the algorithm adjusted gain between about 14 dB and 43 dB.

Jim you do a have point there, thatās a separate parameter indeed not listed in the post. My bad, sorry for the confusion there.
