I do not think that this is necessary, the oscillator frequency drift is very small. Although it may be strongly shifted from the declared frequency. I have a cheap dongle...

"There seems to be sometimes some dongles with serious drift: https://github.com/jvde-github/AIS-catcher-for-Android/issues/6" I think this is just a defective quartz oscillator. Although if the addition of automatic frequency correction is not...

I'm talking about it https://github.com/flightaware/dump1090/blob/master/README.adaptive-gain.md

It works very well for taking ADSB and since the types of signals and the conditions of reception are similar, in theory it should also work well with AIS. ![Screenshot...

I also noticed something strange, immediately after the Ais-Catcher restart, there is a reception of distant and weak signals, but then they stop. AGC is turned off. Here are my...

30min after restart ais-catcher These are not ships, but basic stations and navigation buoys, so that the signal level from them should be approximately constant. ![Screenshot 2023-01-11 at 16-16-52 AIS-catcher...

I noticed this in the process of setting gain. It’s just that every time I change the gain level, I received a reception of weak signals, but after a short...
