What is a SQ? Functions and How to use it?

SQ means squelch control. The receiver needs to receive a certain degree of RF signals in order to maintain clarity of sound quality. When signal strength falls below the signal/noise ratio, the SQ will activate, muting the receiver and preventing noise output. Due to certain noise strengths, SQ must be adjusted to eliminate interference signals. If SQ activates at 12dBuV and when SQ is adjusted clockwise, it strongly eliminates external noise, however, it shortens the operating distance.

When stand-by receiver is being interfered, SQ can be adjusted this way to eliminate the problem. When noise persists at this adjusted maximum level, it means the external interference signal is too strong. In this situation, substituting a new system with a different frequency is advised.
