The following topic should be of interest to all. If you sort your scanner banks or System frequencies in order from low to high, or high to low, you can make a significant improvement in how much time is takes to make one complete scan. This applies to all scanners, and has be verified by the Uniden Tech(UPman), and explained in the following thread:

Here are the results done by the software author of FreeSCAN.
" I created 3 conventional systems, each had 500 channels. One system was ascending, one descending, and one was in random order. I uploaded them and then using a stop watch I timed how long it takes to do each channel. Here is what I got (averages):
Scanning Up: 9.8 Seconds
Scanning Down: 9.7 Seconds
Random System: 17.9 Seconds
So the answer is to make sure the frequencies are sorted to get maximum scanning speed, though it doesn't matter which direction they are in. Having them sorted can nearly double the scan speed."
ARC Butel] and FreeSCAN. software will automatically sort your frequencies just by double clicking on the freq column. I suspect other software will do the same. If not, you can copy your data into a spreadsheet like Excel, or the new free on-line Google Spreadsheet[/u][/url], sort it there, and then copy/paste it back into your software. For some illustrated examples of how to do this, check this TOPIC
Most of us have our data arranged in some logical order that groups similar things together. You can still keep that order in your software. I just sort the frequencies low to high, download to the scanner, but I don't save that version in my software. You can also save the sorted version in another set of files.
Another tip for Uniden DMA scanners: Make sure all your System Hold Times are set to zero (this is not the same as channel delay). The default is often 2 seconds, which really adds up (an additional 10 seconds to complete a scan for only 5 systems.)
