bank once, while in locked out review mode, hold down L/O for 3 seconds. All locked out IDs in a bank are restored.

setting the delay mode for trunking mode

A default delay of 2 seconds is automatically set for each talk group for ID scan mode and ID search mode. To set the delay feature on or off, press DELAY while trunking. DLY will appear or disappear, depending on your setting.

trunking frequency confirmation

You can check the frequency while a talk group ID is active.

Press the d key, and the active frequency on which the talk group is transmitting will flash on the display. Or press and hold the d key for 2 seconds. The ID and the frequency alternately appear on the display. To cancel this mode, press the d key again.

Note

This feature is applied to ID scan mode and ID search mode.

setting priority in trunking mode

You can set priority in your scan lists, just as you do in your conventional ones. The default setting for the priority ID is the first location in each scan list. You can set the priority by pressing and holding PRI for 2 seconds in ID scan hold mode. After you’ve set up your scan list, press PRI to activate it. It is very similar to conventional priority although there is no “interrupt” during the transmissions. Priorities are checked in between transmissions.

With priority on, you can hold on an ID in your scan list, such as scan list 3, memory location 7, and the scanner will check all the priorities in all the active scan lists in between any transmissions on the ID on which you’re holding. The lowest numbered priority will be checked first. For example, the

PRO-2051 specifications

The Radio Shack PRO-2051 is a standout model in the realm of scanner radios, known for its advanced features and user-friendly design. This unit is particularly favored among hobbyists and professionals alike for its superior performance in receiving a wide variety of radio frequencies.

One of the main features of the PRO-2051 is its wide frequency range, which spans from 29 MHz to 1.3 GHz. 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.
