glossary

Channel - a programmable memory location. Channels are grouped into channel-storage banks. Your scanner has 10 channel- storage banks and each bank has 100 channels.

Channel-Storage Banks - Groups of channels, used for frequency storage.

Data Skip - allows your scanner to skip unwanted data transmissions and reduces birdies.

Highway Patrol/State Police Alert - warns you when you are within about 3 miles of highway patrol/state police units.

Hypersearch - increases the search speed to 300 steps per second for search ranges with 5 kHz steps.

Multi-Track- tracks more than one trunking system at a time. You can scan conventional and trunked systems at the same time.

PC Programmable - allows you to easily program all frequencies and trunking talk groups into your scanner through a software running on your PC.

SAME Weather Alert - automatically sounds the alarm tone to advice of the hazardous weather condition and indicate the event of the weather condition.

Service Banks - preset groups of frequencies categorized by the type of services that use those frequencies.

Signal Stalker - lets you set the scanner so it detects then displays the frequency of a nearby strong radio transmission.

Skywarn - lets you jump directly to the last channel in memory (Channel 1000) from any transmission. You can program this channel with the frequency of your local Skywarn broadcaster.

Trunk Tracking - lets you follow VHF high band, UHF 800MHz trunked public safety, and public service systems just as if conventional two-way communications were used.

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.
