The BCD436HP is the first scanner to incorporate the HomePatrol-1's ease of use in a traditional handheld scanner. Simply enter your zip code, and the BCD436HP will quickly select and scan channels in your local area. It's direct sibling is the mobile/desktop BCD536HP which includes a Wi-Fi Dongle, both utilize the same Sentinel (Uniden software), and can be used interchangeably for both on one PC. Here is a quick rundown of the BCD436HP's major features.


  • Flexible Easy Channel Selection using Zip Code or GPS and Service Types - just pick the kinds of channels you want to hear and tell the BCD436HP where you are and let it do the rest.
  • Range Control - Lets you set how far out from your current location the scanner will search for Channels in Favorites Lists and the Database. Location precision for Departments and Sites that allows you to define a location and range using rectangles instead just of a single circle.
  • Serial GPS input for location-based scanning using the Uniden GC-GPSK or other compatible GPS receiver.
  • Complete Front-Panel Programmability - create custom Favorites Lists either using systems from the main database as a starting point or program your systems from scratch.
  • Included Sentinel Software makes database and firmware updates simple. Also allows you to create, edit, and manage your Favorites Lists.
  • USB PC Connectivity (USB Mini-B)
  • Discovery Modes help you find new channels on trunked systems and frequency ranges.
  • Analysis Modes include Band Scope, RF Power Plot, Trunked System Analysis, and EDACS/LTR LCN Finder.
  • Flexible Scanning - scan from any combination of the main database and Favorites Lists.
  • Instant Replay - Plays back up to 240 seconds (4 minutes) of the most recent transmissions.
  • Audio Recording - Capture transmissions for later playback.

  • TrunkTracker V with support for APCO Project 25 Phase I and Phase II, X2-TDMA, Motorola, EDACS, and LTR Trunked Radio Systems.
  • Multi-Site Trunking - Lets you program the scanner to share trunked system IDs across multiple sites without duplicating IDs.
  • P25 One-Frequency Trunking - The scanner can follow individual talk groups on P25 single-frequency systems that use both NAC and TGID’s for squelch control and user identification.
  • Individual Site P25 decode Threshold, Settings: Auto, Manual, Default
  • 100 Quick Keys for Favorites Lists, Systems, and Departments.
  • Startup Configuration
  • Programmable Alert LED with 7 colors and 3 patterns alerts you when a channel becomes active.

  • Channel delay 0-2,5,10,30,
  • Negative Channel delay or dropout (forced resume) adjustable to -2, -5, -10 seconds.
  • 64 character text tagging for each system, site, department, channel, talkgroup, search range, Tone-Out, and SAME group.
  • Date/Time indication on display with time stamping for recordings.
  • Channel Alert
    • Independent Alert Tone Volume – lets you set the volume level of the following tones: Key Beep, Emergency Alert, Channel Alert, Tone-Out hit, and Close Call Alert.

  1. Requires optional paid upgrade with registration via and upgrading firmware to 1.10.02
  2. Requires optional paid upgrade with registration via and upgrading firmware to 1.11.15 (or better)

Main issues

1. Many users reported very poor sensivity on UHF. Touching the batteries seem to improve reception in that case. Uniden did not officially confirmed the problem but proofs in the topic show that Uniden made several revisions of the hardware - not all are affected. This causes problems with receiving relatively strong signals of e.g. EDACS systems.

2. Some units have problem with RTC battery - time need to be adjusted again and again. Uniden launched repair campaign.

3. Wrong TGID's displayed. Uniden is aware of the issue and is working on it with help of the community.
