Monitoring Networked Motorola and P25 Systems

Some of the systems that are preprogrammed in your scanner are networked, multi-site Motorola systems, such as Smartzone, OmniLink, and networked P25 systems. These systems are designed to cover very large areas by using multiple networked transmitter sites, each with its own set of frequencies.

Your Advanced Digital Scanner includes a Multi- site feature that can enhance the operation of the scanner when monitoring Multi-site systems. Multi-site can be enabled by editing the trunking system (TSYS) parameters for the system. Multi- site can be set to Off, Stat (Stationary), or Roam. By default, Multi-site is set to Off.

To activate Multi-site mode on a preprogrammed Motorola or P25 networked system:

1.Press PGM (PROG), then navigate to a talkgroup on the networked multi-site system using the S T W X keys.

2.Press the EDIT softkey, then press the CURR softkey.

3.Scroll down to the TSYS item and press the SEL key to edit the TSYS parameters.

4.Scroll to Multi-site. Use the W X keys to select Off, Stat, or Roam. When set to Off, the scanner will find the first usable control channel in the control channel list and use

it until it is no longer usable. When set to Stat, the scanner will track the system using any control channel in the list that is usable. When set to Roam, the scanner will attempt

to locate and use the best possible control channel and ignore others, until the control channel is no longer usable, then it will locate a new “best control channel” to use. Roam decisions are made using the Threshold

Hi and Threshold Lo settings. For more information on Multi-site, please see “Multi- Site Mode On Networked Systems” in your User’s Guide.

5.Press the SAVE softkey to save your changes to the TSYS parameters, then press the SAVE softkey again to use the scanner.

6.You should experiment with different Multi- site modes and threshold settings to find a combination that works best for your location. Keep in mind that the threshold settings

are only available when Multi-site Roam is selected.

7.Multi-site functionality is not available in EDACS or LTR trunking.

Monitoring Networked EDACS Systems

Some of the systems that are preprogrammed in your scanner are networked, multi-site EDACS networks. Like Motorola and P25 networked systems, these EDACS systems are designed to cover very large areas by using multiple networked transmitter sites, each with its own set of frequencies.

EDACS trunking is quite different from Motorola and P25 trunking. With Motorola and P25 trunking, the subscriber radios on the system (and your scanner) get all of the system channel frequency information from the control channel, which simplifies wide-area networked system scanning. In EDACS, it is necessary to program

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.
