Please check the following test version against issues you were having. Specifically, this should fix the P16 voice interrupt issue and P16 digital voice squelch tail issue, but could have a positive (or negative) affect on other issues.
This version also includes the P25 filter and P25 mode options as a hidden menu. Really want to know whether this provides acceptable quality on AUTO, but if it does not, turn on the hidden menu by going to the Audio Options menu and pressing the blank area in the bottom right corner for 2 seconds or so. Then, try other modes/settings and report.
If you have the symptom of no reception while the scanner seems to be stopped on a channel, we've got a logging function to help capture what is happening.
Before turning on the logging function, set up the scanner to scan only the problem system. Then, to turn on the logging function, do the long press again on the Audio Options page (or twice if you've not done it at all). "P25 Logging On" message will appear. Press "LISTEN" and logging will start. Log for 10 minutes or so, (or at least until you capture a few instances of the no reception issue) then press MENU to close the log file. Power off to finish the test.
The log file will be in a log menu in the file folders on the scanner. Post that file here (you might need to zip it, first) along with a description of what you were scanning and what happened.
To apply the update, download and unzip:

Thanks again for your help.
