Listening Safely

Do not wear headphones, earphones, or earbuds while operating a motor vehicle or riding a bicycle. This can create a traffic hazard and could be illegal in some areas.

To protect your hearing, follow these guidelines:

•Do not listen at high volume levels. Extended high-volume listening can lead to permanent hearing loss.

•Set the volume to the lowest setting. Then turn on your audio device and adjust the volume to a comfortable level.

•Avoid increasing the volume. Your ears will adapt to the volume level, so a level that does not cause discomfort could still damage your hearing.

33-1187 specifications

The Radio Shack 33-1187 is a versatile and innovative device that has garnered attention among amateur radio enthusiasts and hobbyists alike. Known as a compact and user-friendly scanner, this model is particularly popular for monitoring various types of communications, including public safety frequencies, aviation channels, and other broadcast signals. Its user-friendly interface, coupled with a range of features, makes it a valuable tool for anyone interested in capturing live audio transmissions.

One of the standout features of the Radio Shack 33-1187 is its 100-channel memory system, allowing users to store frequently used frequencies for quick access. This functionality is particularly beneficial for those who frequently monitor emergency services or specific radio stations, as it enables instant retrieval of channels without the need to manually tune in each time. The device covers a wide frequency range, typically between 30 MHz to 900 MHz, including several bands that capture both analog and digital signals.

The Radio Shack 33-1187 employs advanced scanning technology that includes features such as priority scanning and delayed scanning. Priority scanning allows users to monitor one designated channel while still scanning through other channels, ensuring that important communications are not missed. Delayed scanning gives the user a brief pause before resuming the scan, providing ample time to hear the entire transmission on the selected channel.

Another advantage of this scanner is its ability to handle a variety of modulation types, including amplitude modulation (AM) and frequency modulation (FM), which enhances its versatility. In addition to conventional radio frequencies, the 33-1187 can also pick up some trunked radio systems, making it relevant for monitoring modern communication methods.

The design of the Radio Shack 33-1187 is straightforward, featuring a clear LCD display that simplifies operations and enhances usability. The control buttons are intuitively laid out, allowing users to navigate through options effortlessly. The unit is compact and portable, making it ideal for both home use and on-the-go scanning.

In summary, the Radio Shack 33-1187 scanner stands out for its reliability, user-friendly operation, and comprehensive scanning capabilities. With its strong memory storage, frequency coverage, and ability to monitor a wide range of transmissions, it remains a favored choice among both novice and experienced users in the world of radio communications.
