What are the functions of SQ and ASQ in MB1 CB Mobile Radio?

In CB Radio, the terms SQ (Signal Quality) and ASQ (Audio Signal Quality) may not directly correspond to standard CB radio terminology, because CB radio usually uses more direct and simple parameters to describe signal status. However, we can give a general interpretation to both terms, both literally and from the perspective of possible applications in the field of communication.

SQ (Signal Quality):

Definition: Signal quality generally refers to the clarity and understandability of radio signal transmissions. This can be affected by a variety of factors such as signal strength, interference, noise, attenuation in the transmission path, etc.
Function: In CB radio, signal quality is an important indicator for evaluating communication effects. If the SQ is high, the received signal is clear and easy to understand. If the SQ is low, then the signal may be interfered with or attenuated, making communication difficult.
Representation: On some radios, SQ may be displayed as a number or bar graph to represent the current received signal quality.

ASQ (Audio Signal Quality):

Definition: Audio signal quality usually refers to the clarity and fidelity of audio signals after radio transmission. This includes factors such as the audio's frequency response, dynamic range, distortion, and more.
Function: In CB radio communication, the quality of audio signal directly affects the quality of voice communication. If the ASQ is high, the speech will sound clear and natural. If the ASQ is low, the speech may be distorted, blurred, or contain noise.
How it is represented: Audio signal quality is often not directly quantifiable through lights or displays on the radio, but it can be assessed through auditory perception.

It is important to note that in CB radio or other similar radio communications, the specific terminology and parameters may vary depending on the device, standard and manufacturer. Therefore, in actual applications, it is best to refer to the user manual or related documentation of the radio equipment used to understand the specific terms and parameter meanings.

SQ and ASQ in MB1 CB Mobile Radio

Automatic Squelch, or ASQ, is a feature in some radios that automatically mutes the radio's audio output when there is no transmission or a weak signal, thereby eliminating background noise and hiss. It's important to note, however, that ASQ is primarily designed for use with FM signals, which means it may be less effective when used on AM signals. While using ASQ on AM signals may help reduce background noise, it may also result in you not hearing distant signals.

Therefore, to obtain better results when using AM signals, it is recommended that you use a regular squelch setting that can be manually adjusted to your preference. With regular squelch, you can adjust the threshold at which the audio output is muted to your liking, allowing you to hear weak signals without being disturbed by background noise.
