Then it's really slow. When that J401 connector between logic and radio circuit board are bad it has sometimes resulted in a slow scan rate of less than 10ch/s. If it gets too many communication errors between circuit boards it probably cannot recover from it and goes into "safe mode" until you reset it.
Can you do a debug log, as that will show what the scanner are doing, and Uniden will certainly need that as well to try and see what is happening. In the log it shows the timing and when frequencies are sent to the radio module and when the lock signal are received from the radio that indicates that the squelch should be tested and if carrier are detected it starts to evaluate the modulation.
I remember reading some instructions in one of these posts about how to capture error/bug information from the scanner, then sending it to Uniden, hopefully to help them address some of the issues with the SDS100. Can someone walk me through how to do that? Having issues with conventional P25...

Uniden have said that they will have nothing to do with euro and pacific territorial scanners so probably Avera or whatever distributor that sells those scanners needs to be notified of the problem, if the US versions doesn't have the same issues.
