Radio Shack introduced the “simple” scanner with the iScan series, designed for users who might find traditional scanner programming daunting. While the menu system is presented as straightforward, it’s not always entirely intuitive. These scanners leverage SD cards for practically unlimited memory and compatibility with databases like the RadioReference Database for the US. Similar to models like the PSR500/310, the iScan series often employs object-oriented memory for channel storage but may have limitations, such as the number of play lists. Typically, free software accompanies these scanners, facilitating uploading, downloading, firmware updates, and database management.
However, the emphasis on simplicity in iScan trunking scanners sometimes leads to omissions. The streamlined menus, a less comprehensive keypad, and the absence of certain advanced features found in models like the 500/310 can deter some users. These scanners are truly optimized for users who prefer a “set it and forget it” approach. Although basic object editing and library imports are possible directly on the scanner, more complex tasks necessitate using the companion software. This includes programming individual frequencies, setting receive modes, pre-configuring CTCSS/DCS tones/codes (though these can be stored on-the-fly), adjusting delay times, toggling audio boost, and crucially, updating the scanner’s firmware. Furthermore, the programming and configuration of all trunking systems and sites are exclusively managed through the software. Conversely, settings for searching and Signal Stalker functionalities are inexplicably only accessible via the scanner itself, lacking software options.
The interplay between various settings can also introduce confusion, even for experienced users. For example, managing alerts involves navigating multiple menus: one to activate alerts globally, another to adjust the alert volume, and yet another to designate specific objects for alerts. Attenuation settings also appear across different menu levels (global, system, site, object), requiring careful attention to ensure correct configuration.
Certain design choices might seem illogical. Performing quick edits to a channel, such as adjusting attenuation, lockout, or priority settings, results in excessive delays as the scanner rewrites data to the SD card. Additionally, the provision of only a digital manual on CD, without a printed version, is inconvenient. The reliance on a PC for full programming and editing of a handheld scanner is a notable drawback. Perhaps the most significant inconvenience is the necessity to remove the SD card entirely – which often requires removing the batteries to access – and use an external card reader for any data uploads or downloads. The USB cable is limited to firmware updates and battery charging. This aspect feels like a step backward in user-friendliness.
Given the limited on-device settings and options, the iScan software becomes indispensable for customized programming. Therefore, understanding the software is crucial to fully utilize the scanner’s capabilities, especially for trunking systems. While the original manual’s organization may be lacking, resources like online forums and user guides can significantly enhance the user experience. Upgrading the stock antenna is also generally recommended to improve reception quality. For users new to trunking technology, grasping the fundamentals of trunking is essential before attempting to program trunking systems. Understanding concepts like control channels, IDs, and LCN order is vital for successful setup and operation.
In conclusion, iScan trunking scanners offer a simplified entry point into the world of scanning, particularly for beginners. However, their full potential, especially for trunking system monitoring, is unlocked through the use of the iScan software. While the scanner presents a user-friendly facade, mastering its advanced features and navigating its quirks requires delving into the software and potentially consulting external resources for optimal performance.
