pcrguy has an IC-7300 and can't say enough good about it. Good choice!
If I'm experiencing Weather Radio interference on the rail band, I assume one of the Invert filters (low pass) would help?
I use SDS100, but that would not create a new thread, I will write here.
If in the Srch/CloCall options menu, the settings of the filter "wide-normal", "wide-inv", "wide-auto", then the Closecall does not work on the UHF and 800MHz band
When the “wide xxx” filter is turned off in the settings, the closed call works.
I ask owners sds200 to check this bug.

When choosing either Auto or Wide-Auto, my understanding is that the scanning slows down while the radio samples the best filter to use.
Based on what criteria, the scanner determines the best filter to use?
Once it does decide, does it always use that particular filter setting?
What criteria/condition would change that forces the scanner to use another filter setting?
And lastly, would it be possible to include in another FW update, a field that shows the filter selected by the scanner as its best choice?

No
If you are mobile it would be different conditions as soon as you start to move.
If you are stationary the auto mode would only be used to see if the scanner could make reception better and then you set the filters manually, after experimenting out which one to use and also include IFX, to get a higher scan rate.
Most things can be done in software and in the x36 scanners you could get the value to be displayed that auto mode for digital threshold had selected. This is the exact same thing but would be done as one of the variables to be used in one of the info fields.

That's all well and good, but, there's what...eight combinations to try? That's a lot of button pushing and scrolling then back to listening to see what works best. I thought an option could be made to, inform the user, what filter the scanner is using when in auto. Although I can also see why not, as the scanner does not know when I'm stationary or moving. I'm not too sure as wether IFX would be of any help. From what I read so far, it is used when getting interference from a nearby frequency(?). I mostly listen to 800Mhz digital, no analog, and at any rate, if I ever need to use IFX on digital, how would I know an adjacent frequency is causing interference?
Thanks for your reply.
“and also include IFX, to get a higher scan rate.”
What is IFX? How is it chosen? A previous post suggested “Normal Wide” as a starting point when determining what filter setting to use... but if Normal Wide affects scan rate adversely, I’d like to incorporate this IFX... or is IFX something that’s incorporated AFTER a proper filter other than Normal Wide is chosen, it not being available with Normal Wide?
Auto filter mode is the only filter mode that can slow down scanning and searching as it checks all filter settings each pass.
To turn on IFX for a frequency, press Function then 7 to enable it or disable if already enabled. You may need to be held on a frequency before Function plus 7 works. This can help when intermod is present on a frequency or if a nearby frequency is bleeding over.
Thanks for the help. Is IFX mentioned in the manual? I don’t recall seeing it. What does it stand for and what does it do?

"Intermediate Frequency Exchange"
It changes the frequency of the IF Section of the radio.
IF Section
Does IFX Do Anything?
Understood. That’s a blast from the past! I remember manufacturers offering to change the Intermediate Frequency when there was the need as you mentioned. Thanks.

I cannot find a comprehensive chart of the function/result of each available filter. Global filter seems to be the default, but there is also NORMAL, INVERTED and more.
Is there a difference in results with a conventional vs a trunked system ?
ANY informative info will be appreciated.

Anyone else find it a little unsettling even Uniden themselves doesn't seem to know?
Deleted covered in multiple threads.
Nope not at all in my case as everyone's results will be different more than likely.If that is a concern as always return the item or sell it.
I'm pretty sure Paul stated that they won't publicize the specifics of each filter for confidentiality reasons.
And as mule1075 posted the basic function of each has been posted.

I don't know either but having just started to play around with the filter settings I've found out that having the "right" filter setting on my SDS100 can make the difference between reception and accurate tracking of a trunked system or no reception at all, nothing, nada, zip. The filter settings made a lot more difference to reception than I ever thought they would.

I wasn't implying I wasn't happy with the situation, I don't even own one (yet). I just don't understand why it was designed with features that no one apparently understands what they do or how and when to use them. Would you accept a new vehicle with a fancy computer/navagation system you paid extra for but you can't even use it? It was designed by Uniden correct? Did the engineer quit?
This is why Uniden could build a SDR Scanner and WHISTLER gave up the secret code and not tell how it works.

Maybe Whistler sold the filter technology to Uniden and didn't supply the instructions?
