It is interferencies that makes the scan hesitate and slow down. When you have no interferencies, pretty much impossible with a SDS scanner, it will always scan at full speed, 45ch/s. Even if you remove the antenna it will have hickups in the scanning from the internal interferencies in the scanner, even the display in SDS100 emits interferencies when the backlight are on.
Hi all, I hope everyone is healthy and well. I have a question that has probably been covered but I can't quite find what I'm looking for. As for the filter settings, which filter (wide or not) actually creates a tighter or smaller window to the frequency being monitored. Or if someone knows...

The only parameters the scanners logic can look at are Noise level for analog channels and also D-error for digital systems. It has to test each filter and use the one that gave the best result. It has to sample the signal a fairly long time to be able to make a good choise.
If you use Auto filter it will slow down scanning and you might not catch conversations happening in other systems as it will take a long time to do a full scan cycle. If you do not use Auto you could experiance total blackout of some frequencies so that you miss conversations where those frequencies are used. Neither option are really any good. If you only scan very few systems would Auto be prefered.
