You can't use a SDS scanners RSSI reading for any serious work.

I monitored a frequency in the 400Mhz band with a signal of -100dBm, just a little noise in it so it can be heard if the sensitivity changes. I used the filter set to Off, which is the standard symetrical filter used in any other scanner.
I injected a -50dBm signal and at a frequency 7MHz lower than the monitored one. The RSSI changed from showing -100dBm to -60dBm.
When I got within 3MHz it started to show -50dBm.
All of that is irrelevant to my suggestion. If RSSI reads in 10dBm increments vs 1, it's much harder to evaluate the efficacy of various filter settings on dealing with adjacent frequency interference. If the hardware supports it, it's worth doing for that reason alone, regardless of any other considerations.

Thanks for taking on the challenge, Joe. Looks like you know your stuff and have a good attitude towards this, based on your posts the past few days. Enjoy the ride.

Joe - Thanks for taking and filling a needed spot for Uniden. We all appreciate it!!

One wish I have is that Uniden has a dedicated space for the Firmware updates of its current models.
One page to check to see if I am current or not...instead of digging in this forum. Wish that Uniden would host the firmware on their support site. That is my only wish.

No rush on updates my SDS models are working GREAT....
Thanks,
RICH

Have you seen these Uniden firmware pages on their site? ... here are a few examples:

You probably ignored the link I gave you.

Nearby frequencies will reduce the receivers gain and sensitivity. The RSSI indicator starts to react to signals as far away as 7MHz from the monitored frequency. It's difficult to have a good RSSI meter when the signal starts to go up in the -60dBm strenght, as the measured voltage from the receiver chip has very small differences at those signal levels. It sometimes jumps from -60 to -40 and the -40 got stuck a couple of times even when lowering signal to -90dBm. It's a very unreliable indicator. When it works, with a single pure signal source, it shows about 5dB too much but seems to be usefull up to -60dBm.

But.....the question remains, "who is this Joe Bearcat?". Is he really an employee of Uniden, or taking on a pseudo personality to fool us all? :unsure:

@fxdscon - Yes have seen these...but in my opinion they should be linked off the Uniden Support Page or even off the product page for the particular scanner like the SDS-100 / SDS-200 etc.

Hello, I am closely following the new updates and I want to see the Tetra protocol in Uniden SDS100 as one of those who voted. Good luck and health!

Welcome to the forums, Joe. Paul is certainly missed and left a big void. It’s great to have someone from Uniden here again. Best of luck!

Hi Joe,
Glad to see you on the forums and you have some big shoes to fill. :)

If you'd like to be a guest on the "Scanner School" podcast to share your background and updates on Uniden, please reach out to me...

Uhm, yes! I’m already excited about this😀.

Hey JB! Welcome to the Radio Reference Jungle!! Glad that you are stepping up as a Rep here. It's also good to hear that Uniden is still actively updating existing products and also pursuing new ones. We all look forward to hearing more about these updates and new offerings. Thanks again for taking on this role and I hope you don't lose too much hair or develop a drinking problem along the way! LOL!!
Good luck!
Tim

Your wish has been granted. If you try to update the firmware by using Sentinel and clicking Update>Update firmware, you will be told if your scanner is running the latest and greatest.
