2 & 9 hold down
Did you follow the procedure on the download page?
To adjust the decode threshold, start with the scanner powered off. Then, follow these steps:
While holding down the HOLD button, power on the scanner.
Access the hidden P25 Adjust Mode menu by MENU --> Settings --> P25 Adjust Mode.
Set the mode to 11, which is the optimal setting for most P25 systems.
If you have previously adjusted the P25 Adjust Level, reset it to a value of 50 by MENU --> Settings --> P25 Adjust Level.
I have the 396XT not the 996.
One other thing that may or may not be important...
I am using the Prolific USB-to-Serial Cable in Windows 7 Pro. The driver version of the COM 3 port is 3.3.0.1 (1/31/2008)
Wondering if anyone else is using this same driver. I can't find a newer driver online. But again this driver works communicating with my scanner in FREESCAN with no problems.

That is the manual adjustment that was added.
I know Paul but that menu or adjustment has been there for a long time!
The hidden menu has always had that exact setting.
Is it different or something?
Mine looks exactly the same as it did in the older firmware with the same lower and upper limits of 3 and 15 so nothing new that I can see or am I blind!
Thanks!
What I am seeing here is that when the mode setting is set to 8 or above, it acts like a manual setting. My 396XT goes directly to that threshold setting at the beginning of a transmission (i.e. mode 11 = threshold 11). If mode is set to less than 8, the threshold seems to be the same old auto setting and my scanner goes to a setting of 12 at the beginning of a transmission.
The mode setting seems to set an upper limit on the auto threshold adjustment.
Ha, neither of mine act like that at all. I set the P25 adjust mode to 3 and it starts at 8, I set it to 11 and it starts at 8, I set it too 15 and it starts at 8! Mine (the 396 and 996) both start at 8 and then bounce around between 8 and 11 but never settle down. I surely cannot get it to go down to 5.
Mine both exhibited this exact behavior before this firmware update as well hence the reason I'm asking what is really new.
Thanks for trying to explain what you think you are seeing. I wish I could see that so I'd at least know my settings are changing something!
I cannot force mine to start at 11 like yours for anything. It is always 8.
I'm puzzled.
Ive been adjusting around with mine. Right now I am using a level of 140 with a mode of 8 and getting decent results on the Charlotte Project 25 system....Seems to be a small improvement over the older version but still fine tuning it here...
Yes I didn't explain very well. Mine always starts at 8 as well but when a transmission starts it then changes the threshold to the same level as the mode setting. The scanner doesn't seem capable of adjusting threshold down. It always starts at 8 and goes up from there although you say you see it go up and down??????????

I beleive you are right about the lowest setting that is usable on P25 mode is 8...If I set mine to 7 then the auto setting starts flying back up to as high as 13 and back down to 8....By setting the mode to 8 then it constantly stays between 7 and 8 and doesn't vary outside of that boundry and it makes the copy much much better...Now I am going to leave my mode at a setting of 8 and adjust the P25 level upwards of 125 to 160 level and see if I can fine tune it...The systems that I am monitoring are settleing in at level 7....
Are you running yours with the suggested value of 50 for the P25 Level?
