When Uniden came out with firmware updates, I installed (I think) v 3.2. My 800 reception was horrible. I replaced it with an older firmware. I want to install rebanded systems. Did Uniden come up with a "fix" for this?
I seem to recall a great deal of discussion about this when 3.02.02 came out. If memory serves, the consensus seem to be that at least some folks found the decoding to be better if you switch the APCO mode to MAN (not AUTO) and set the threshold to 8. Also having the right modulation type is important - you didn't mention the system you were having trouble with, but NFM shouldn't be used unless your system is narrowbanded. Be sure the modulation is set to FM, not NFM.
Unfortunately Uniden seems to have issued its last firmware fixes for the older T scanners - they seem to be concentrating more on the XTs, and at least reportedly, the decoding is much better on the XTs. However, you didn't mention whether your system is simulcast - there's a detailed article in our wiki about the distortion that occurs with such systems. All consumer grade scanners are going to have some degree of trouble with such systems.
