Im curious how effective is the zip code thing? Im sure it would leave some things out? Does it only load police/fire/ems or will it also pull stuff like air towers at air ports, and other such items in that zip code?
Before purchasing, you can determine exactly what will be loaded into your scanner for the zip code or scanning range that you enter into the BCD436HP. Keep in mind that the scanner doesn't scan "everything" in range of the zip code that you enter. It only scans those items that
are already in the database within range of your zip code. There are countless frequencies in use that are not listed in the database for one reason or another. The database is derived from the database right here on Radio Reference, and is pretty much powered by user contributions.
Download the latest version of x36 Sentinel software here:
BCD436HP < UnidenMan4 < TWiki
You don't need to have the scanner in order to use the software.
Very important to read and understand this first.... as to exactly how location based scanning works:

After you have the Sentinel software up and running on your computer....
From the top menu click "Update", then "Update Master HPDB". It will either go through the update process or tell you that it is already up to date.
Then, from the top menu click on "Edit", then "Add channels on range".
In the window that comes up next, click the "Zip/Postal" button and enter your zip code. That will automatically set your Lat and Lon, and set your range for 10 miles as noted in the article referenced above.
Choose the service types you are interested in, or select all of them to see everything you can expect to be loaded. Then click "OK", and in the next window, click "New Favorites List" and give it a name, then click "OK".
Your new favorites list will be seen when you expand the tree in the left side of the window, and you will now see in the right side of the window what will be in your scanner based on your zip code and choice of service types when you click on the items listed in your favorites list.
To experiment with different ranges and service types, repeat the process to add another favorite with a different name and different "Range" selections from the drop down window (other than the default of 10 by entering your zip code) and/or select different service types. Then you can compare the different favorites to see what would be loaded.
You can add anything to that favorites list that is not in the database, or delete things that you don't want, or make many other customizations by using the favorites list editor in Sentinel....
Click "Edit", then "Edit favorites list".
