Uniden Home Patrol FAQ

From The RadioReference Wiki

Please document all issues and solutions that pertain to the HomePatrol-1 and HomePatrol-2 here. If it's not in the owner's manual, please consider documenting it here. Be as specific as possible as to the steps taken - the devil is in the details. The more detail you provide, the better.

NOTE: We have separate FAQs for other Uniden products;

The Nuts and Bolts

  • If you're a newcomer, you've probably already discovered that there are a huge amount of terms that seem unfamiliar to you. Our Glossary has lots of these terms, along with definitions. Just click on the term you wish to view.
  • When looking at frequencies in our database, float your mouse over the column header, and you should get a balloon with a brief description of the terms and abbreviations that are used there.
  • The biggest hurdle for many is the concept of trunking. Our Trunking Basics article will get you started, as well as this PDF file written by UPMan. Note that you will need Adobe Acrobat or a compatible reader (such as Foxit) to read it.

Operations Issues and Fixes

  • How do I use Favorites?

  • Are Favorites Lists automatically updated when the database is?
    • No. It is prudent to keep an eye on the favorites lists you use regularly and compare them to the latest database.

  • Where can I purchase the Extreme Upgrade for my HP1?
    • See this page from Scanner Master

  • I get a loud buzz when connected to amplified speaker system. How do I get rid of it?
    • Purchase a Ground Loop Isolator (like this one from Amazon) and install between radio and input to speaker system (thanks to kc2rgw)

  • My HP1 is slow to respond to commands on the touch screen
  • Symptom: When the radio restarts you end up at the initial 6 page setup. The favorites and database would not respond
    • Resolution:
  1. Get a new 2 Gig SD card
  2. Use Windows to quick format it before putting it in the Home Patrol.
  3. Connect Home Patrol to computer, open Sentinel.
  4. From the toolbar click on Home Patrol, Clear User Data, check the box for "Display all drives", highlight the drive and then click OK. (thanks to fxdscon)

  • My HP1 powers on but won't respond to the touch screen.
    • The space between the bezel (the plastic frame around the screen, part of the front piece of the scanner) and the touchscreen, while small, is big enough in relative terms for something the size of a sesame seed to wedge in between the screen and bezel at the "bottom" of the screen. This can cause the screen to appear to "lock up" because there is something pressing on it (note the HP uses a single-touch screen unlike the new multi-touch phones, tablets, etc). A business card applied carefully as a means of extracting the foreign object should allow the screen to start functioning again. (thanks to Jay911)

  • What do all those abbreviations I see in the Activity Log mean?
    • The sheet that describes all the abbreviations as used in the activity log mode in the HP1 can be found here. Note that it is a PDF file so you need Adobe Acrobat or one of the other PDF utilities to read it

  • I cant seem to get the recording function to work
    • If you are running on battery power, and the voltage level drops too low, recording functions are disabled.

  • Can I use the discovery mode to record without having batteries in the unit?
    • No you must have a good set of batteries installed for this function to work

Conventional Issues and Fixes

  1. For ARCPATROL, this software comes with a number of files already defined. See the ARCPATROL article for specific files and instructions.
  2. For Power Patrol, you can use the EZ-Grab function to pull frequencies from the articles linked above into a favorites list. NOTE: This software is not compatible with HP1 firmware version 2.0 or newer and is no longer supported.
  3. For Sentinel, see the Sentinel for the Home Patrolx

Trunking Issues and Fixes

  • What causes distortion when listening to P25 simulcast systems? How can it be remedied?

  • How do I define an I-Call? Its not defined in the manuals
    • Note: This will only work with the Extreme Upgrade.

If you are doing it on the Unit and you wish to do ID Scan instead of ID Search simply create a Department named "ICalls" in the system in which you wish to monitor ICalls. Then create a new channel and call it ICall. Then Do the following:

  • That's the "i" (Under the 7) followed by a zero (0).

The i will change to a period like above. Select Accept and you should be good to go.

  • Note: If you are doing ID Search you should not have to do the above.
  • 2nd Note: In Sentinel do the same thing except put in a
    • TGID of "i0" in a memory spot.
  • If done correctly you should see something like this:


  • Then ICalls should start to show up on the display

  • Can Project 25 Phase II Systems be monitored with the Home Patrol?
    • Not with the HomePatrol-1- you need the HomePatrol-2 for this

Tips on Preventing Database Corruption

  • Always turn off the power switch, wait about 10 seconds then unplug it
  • Use recording and the replay options as little as possible
  • Periodically reformat the SD card
  • I am getting a corruption message. My favorites are in (French, Spanish, etc.)
    • Make sure that the Regional Setting in Windows is set correctly.
  • Here is another method to restore your database and the date on the database is the same as the one being downloaded
  1. Look in C:\ProgramData\Uniden\BCDx36HP_Sentinel\Updater\ (note the ProgramData directory may be hidden. Use View and make sure Show Hidden Files is checked
  2. Remove the GZ file in that folder
  3. In Sentinel select Update --> Update Master Database.
