Beyond the Basics

Press TRUNK to start receiving trunked system information. You can receive the trunked system using the ID Scan Mode. You can receive those talk groups that you store in a scan list using ID Search Mode.

You can hear all system talk group activity (except unit- to-unit calls). This mode lets you find unknown talk groups. Your scanner defaults to receive the talk groups in ID search mode. Press SRCH in the ID search mode and the scanner will move to the ID scan mode. If you press SRCH again, it will return to the ID search mode.

ID scan mode

When your scanner finds the control channel data, it begins trunking and id SCAN scrolls on the display until the scanner finds an ID. If you have not programmed any IDs, the scanner cannot stop on an active conversation.

To remove a scan list from active scanning, press 1-9, 0 (the number of the scan list). The scan list indicator turns off, and the IDs in that list are not scanned.

To restore a scan list to active scanning, press its number again.

Note

One scan list must always be active. If you try and

 

deactivate all the scan lists, scan list 1 will automatically

 

be active.

ID scan hold mode

You can press HOLD/RESUME to hold an ID. HOLD and the ID will appear. To resume scanning, press HOLD/RESUME. To move the specific location, press e or d or, using 1 through 9, 0 and pressing HOLD/RESUME, you can directly access the specific location you want to which you want to move. The first number represents the scan list number and the second number represents the memory location number. To access the location number 10, use 0.

This includes the VHF and UHF bands, allowing users to listen to everything from public safety communications to amateur radio. The scanner also supports trunked radio systems, specifically the Type I, Type II, and Motorola systems. This makes it an invaluable tool for monitoring emergency services and other business communications that rely on trunking technology.

The PRO-2051 is equipped with an extensive memory bank, allowing users to store a significant number of channels. With 200 channels available and multiple banks, users can easily segment frequencies for various agencies, events, or interests. The scanner's capability to store frequencies in a user-friendly environment makes it easy for enthusiasts to quickly access the channels they most frequently monitor.

Another noteworthy characteristic is the scanner’s ability to utilize CTCSS and DCS tones. This feature helps eliminate unwanted noise by only allowing signals that match preset codes to be heard. This not only enhances clarity but also allows users to filter out unrelated conversations.

The PRO-2051 includes a backlit display, ensuring that users can read frequency and channel information even in low-light conditions. The front panel’s intuitive layout, featuring a simple keypad for inputting frequencies, adds to the overall ease of use.

Another significant aspect of the PRO-2051 is its ability to serve as a conventional scanner with features like Search Mode and Priority Scan, allowing users to quickly locate active frequencies. Furthermore, the scanner supports "Close Call" technology, which enables it to automatically detect and tune into nearby transmissions, ensuring users don’t miss important communications.

In terms of power, the PRO-2051 is designed for both AC and DC operation, providing versatility for both home use and field operations. This flexibility, combined with its advanced features and robust design, makes the Radio Shack PRO-2051 a top choice for anyone looking to explore the vast world of radio communications.
