Introduction Introduction

For your convenience, the 20 V-Scanner folder storage locations (01-20) are preprogrammed with the frequencies, talkgroups, and configuration data for approximately 350 trunked radio systems in the United States. The scanner’s working memory and V-Scanner folder “00” are not preprogrammed with any data.

Each V-Scanner folder can hold up to 1800 “scannable objects,” grouped in up to 20 Scan Lists. Each V-Scanner folder can contain approximately 20 individual trunked radio systems, or sites within networked systems, leaving room to spare for your own custom programming.

The preprogrammed data in your scanner contains the top public safety trunked radio systems in the United States, those that are most likely to carry local radio traffic that is of interest to many users. Non-public safety systems, airport systems, transit systems, federal systems, military systems, and large statewide trunked radio networks are not included in the preprogrammed data.

The preprogrammed data contains the talkgroups that are used for day-to-day public safety dispatch, response, and operations activities. Administrative talkgroups and talkgroups unrelated to public safety are not included in the preprogrammed data.

RadioShack acknowledges RadioReference.com, LLC for providing this trunked radio system configuration data. For more information

It is not possible to include every trunked radio system and talkgroup in the United States in the preprogrammed data. If the systems in your area are not present, you may find it useful to visit www.radioreference.com to find your local system so that you can add it to the radio’s programming. You can also program a “wildcard” talkgroup that will allow you to hear all activity on the trunked radio systems that you monitor.

The easiest way to add a wildcard talkgroup is to duplicate a talkgroup that is already programmed for the system, change the pertinent data for that talkgroup (in this case, the ID and the Tag), then save the duplicated (and changed) talkgroup as a new object.

1.Press PGM (PROG), then use the S T W X keys to navigate to any talkgroup on the system where you wish to add a talkgroup or wildcard.

2.Press the EDIT softkey, then press the DUPE softkey. A duplicate of the selected object is created in memory.

3.Scroll to the ID: field and press the Dflt softkey, which will set the ID field to “Wildcard.”

20-106, 20-197 specifications

Radio Shack, a name synonymous with electronics retail, has long been celebrated for offering a wide range of products catering to both amateur and professional enthusiasts. Among its notable offerings are the Radio Shack 20-197 and 20-106 models, two distinct multimeters that provide outstanding functionality for both basic and advanced electrical measurements.

The Radio Shack 20-197 is a digital multimeter renowned for its reliability and user-friendliness. This model incorporates a robust set of features ideal for both novice hobbyists and experienced technicians alike. With an easy-to-read LCD display, the 20-197 can measure AC and DC voltage, current, resistance, and continuity. This versatility is complemented by its ability to test diodes, ensuring users can tackle a wide array of tasks with one compact device. Additionally, the multimeter is designed with a protective casing to prevent accidental drops or damage, making it an excellent choice for on-the-go evaluations in various environments.

On the other hand, the Radio Shack 20-106 model caters more specifically to the needs of electronics enthusiasts. One of its standout features is the temperature measurement capability, which broadens the range of potential applications, allowing users to monitor circuit temperatures directly. Like the 20-197, it also measures voltage, current, and resistance, but with heightened accuracy and additional precision settings that professionals may find essential for more intricate projects. The 20-106’s clear and intuitive interface simplifies the measurement process, making it accessible even for those less familiar with electronic diagnostics.

Both multimeters utilize advanced technologies to ensure accuracy and durability. They are equipped with automatic ranging, which eliminates the need for manual adjustment, streamlining the measuring process. The battery-saving features in both models, such as automatic shut-off, also enhance usability, prolonging battery life during periods of inactivity.

In summary, the Radio Shack 20-197 and 20-106 multimeters exemplify quality and functionality in electronic measurement tools. With their extensive features, user-friendly designs, and advanced technologies, these models continue to serve both amateur hobbyists and dedicated professionals looking to simplify their electronic evaluation tasks. Whether measuring voltage levels, assessing circuit temperatures, or testing components, these multimeters make an invaluable addition to any toolbox.
