Software - ScannerFreakDB

1. Overview and Purpose​

ScannerFreakDB is a Python-based database application built to log, organize, and manage radio scanning information. Most off-the-shelf logging tools are either too generic or too rigid, making it difficult for hobbyists and professionals to track detailed frequency data. ScannerFreakDB is designed to fix this by providing a customizable and easy-to-use solution for radio enthusiasts, whether focused on ultralight DXing, UHF monitoring, or general scanning.

With ScannerFreakDB, users can quickly store, search, and categorize frequency data, making it a long-term, flexible tool for anyone serious about scanning.


2. Objectives​

  • Customizable Fields: Include frequency-specific details while supporting further expansion.
  • User-Friendly Interface: Simple, intuitive entry and search options for all users. Android compatiable.
  • Efficient Data Retrieval: Fast, flexible search and filtering functions.
  • Long-Term Usability: Scalable design with no unnecessary complexity.

3. Scope​

ScannerFreakDB covers:
  • A lightweight, local database for managing radio frequency logs.
  • Input fields designed specifically for monitoring and scanning.
  • A simple GUI for data entry, search, and filtering (time/resources permitting).
  • Export functionality for backups, analysis, or sharing.

4. Key Features and Functional Requirements​

1. Data Entry Fields​

  • Covers all required information, such as:
    Frequency
    Name
    Mode (drop down)
    CTCSS/DCS,
    Group (drop down)
    Date,
    Notes
    Programmed (drop down)

2. User Interface​

  • Search & Filter – By frequency, date, user, or log type.
  • Quick Entry & Edit – Fast adding and updating of records.
  • Sorting – By frequency, date, or user for streamlined review.

3. Data Management​

  • Local Database – Lightweight SQLite for portability and speed. This syncs between Windows and Android versions automatically.
  • Export Options – CSV/JSON for archiving, analysis, or sharing.
  • Data Integrity – Validation to reduce errors and duplicates

Review - Uniden BCD325P2-AU




Background

My background in radio scanning goes all the way back to the late 1990s. I was one of the first people in Tasmania to successfully program a Uniden trunk-tracking scanner to monitor the statewide 800MHz EDACS trunked radio network. Since then, I have continued to follow developments within the radio monitoring hobby and have owned a wide range of scanners over the years.

My previous primary scanner was a Uniden UBCD396XT, which served me well for many years. However, the radio landscape in Tasmania has changed significantly. The rollout of the Tasmania Government Radio Network (TASGRN), increasing use of DMR and NXDN systems, and the gradual retirement of older analogue services meant it was time for an upgrade.

In 2026, I decided to purchase the Uniden BCD325P2-AU. While much of the emergency service traffic on TASGRN is now encrypted and cannot be monitored, the network still provides plenty of opportunities for hobbyists interested in system analysis, site identification, control channel monitoring, and testing. At the same time, commercial, industrial, transport, utility, and local government users continue to adopt DMR and NXDN technologies, making support for modern digital modes increasingly important.


Physical

The Uniden BCD325P2-AU uses the same handheld case design as the UBC126AT and several other Uniden models. I have found it to be a comfortable fit in the hand, with a logical button layout that makes operating the scanner straightforward.

The display is a good size for a handheld radio and remains easy to read in most lighting conditions. Audio quality is excellent for a scanner of this size, with the internal speaker producing clear and reasonably loud audio. Ear phones also work well.

The compact design does come with one compromise: the radio uses only two AA batteries. While this results in shorter operating time than larger handheld models that use three AA cells, I have found that keeping several sets of rechargeable batteries available makes this largely a non-issue.


Features

The BCD325P2-AU remains one of the most feature-rich handheld scanners available in Australia, supporting:

  • APCO P25 Phase I and Phase II
  • Motorola, EDACS, and LTR trunking
  • Dynamic Memory Architecture
  • Quick Key system management
  • Multi-site trunking support
  • GPS-based scanning and location control
  • Control Channel Data Output
  • Close Call RF Capture
  • Fire Tone-Out detection
  • Search and Store functions
  • P25 One-Frequency Trunk support
  • Priority scanning
  • Temporary and permanent lockouts
  • Signal strength display
  • Auto Adaptive Digital Threshold
  • Frequency and Talkgroup AutoStore
  • Custom search ranges
  • Large alphanumeric display
  • USB programming and control

For active frequency hunting, search and store functions remain some of the most useful features. The ability to automatically log and save newly discovered frequencies or talkgroups while away from a computer is extremely valuable.


Negatives / Issues

No scanner is perfect, and the BCD325P2-AU does have a couple of shortcomings.

The biggest annoyance is the lack of keypad backlighting. The display itself is illuminated, but operating the scanner in low-light conditions would be much easier if the keypad was also lit.

Battery life is another compromise resulting from the compact size of the radio. With only two AA batteries, operating time is lower than larger handheld models. Fortunately, carrying spare rechargeable batteries easily solves this problem.

The other limitation is simply a reflection of how the radio monitoring landscape has evolved, more communications are encrypted. While this is not a fault of the scanner itself, it does mean that some users may eventually find themselves with less and less to scan.


How It Has Changed the Hobby for Me

This is the area that matters most.

The BCD325P2-AU has put the fun back into radio monitoring. It is small enough to carry almost anywhere and powerful enough to support both active listening and frequency hunting.

The search and AutoStore features have become a major part of how I monitor today. Rather than sitting in front of a computer logging frequencies, I can simply let the scanner search, capture activity, and review the results later before adding them to my database.

Although TASGRN has reduced the amount of monitorable emergency service traffic due to encryption, it has created a different challenge for hobbyists. Identifying sites, analysing control channels, mapping coverage areas, and tracking network changes has become an interesting aspect of the hobby in its own right.

The increasing use of DMR and NXDN systems throughout Tasmania has also encouraged me to expand my monitoring beyond traditional public safety communications. Many of the most interesting discoveries now come from commercial, industrial, transport, and local government users operating on modern digital systems.

More than anything, the BCD325P2-AU has reminded me why I enjoy the hobby. It allows me to get out, explore the radio spectrum, discover new activity, and continue learning. While radio monitoring in 2026 looks very different from the hobby I started in during the late 1990s, it remains just as rewarding for those who wish to put in the time and effort.

Tasmanian FreeScan Configuration Files

I am happy to provide the below FreeScan config files, which cover a large number of radio users across Tasmania and are suitable for use with some Uniden scanners.

Please Note:
- These are provided free of charge, "As Is" and have been tested by myself. 
- No warrantay is offered, if they work for you, that is great.
- I am happy to provide some basic assistance with them.
- Due to my location, I can only confirm active users in the Launceston area. I welcome updates and feedback for users in other parts of the state on active VHF and UHF frequencies.
- These will be updated when and as I have the time or there are major changes to them.

All Config files contain:
Airband
Marine
Amater Radio
27MHz and UHF CB
TasRail
Business Users
Some TASGRN site for each area.
