Why Must Set SQL for Your Retevis RB27 Farm radio?
Radio walkie-talkies communicate via radio signals. Hand-held walkie-talkies are the main component of agricultural radio communications. However, background noise will inevitably appear in agricultural radio communications. This kind of noise is tiresome and causes auditory interference and fatigue to the user. The purpose of setting the squelch level is to control the effect of back noise.
The squelch level is also called squelch level. Although the squelch level of each model is not the same, the larger the number, the higher the level. The smaller the interference of noise or other irrelevant signals, the smaller the noise, but also the less likely it is to receive the useful weak signal that needs to be received. Conversely, the smaller the number, the lower the level, the stronger the suppression of noise suppression, the greater the interference from noise and other useless signals, and the easier it is to receive weak useful signals.
For a professional agricultural handheld GMRS radio, the squelch level of Retevis RB27 ranges from 0 to 9, a total of 10 levels. The "0" level indicates that there is no squelch suppression function, which is the lowest level. The "9" level indicates the highest noise suppression function, which is the highest level.
How to set an appropriate squelch level?
Adjusting the squelch level is to reduce, suppress or eliminate useless noise so that it will not be transmitted through the speaker, but the call signal must be retained. Especially in the special outdoor application scenario of agriculture, sometimes the weak remote communication signal is suppressed along with the noise, which is also undesirable. Therefore, if we want to set the Retevis RB27 GMRS farm radio according to the actual agricultural activities Appropriate squelch level, for example, in a normal agricultural indoor environment, the squelch level can be set to 3 or 4 to receive more effective signals. In harsh outdoor environments, such as high winds and noisy mechanical operating environments, you can set a higher noise level, such as 8 or 9.
How to set the squelch level for Retevis RB27 GMRS farm radio?
There are two ways to set the squelch level of Retevis RB27 GMRS farm radio, one is set by the program software, and the other is to set directly through the menu key of Retevis RB27 GMRS walkie talkie.

Squelch level (SQL)-MENU 03
This function turns on the Squelch when the signal is strong; the Squelch will stay off when the signal is weak. Set the same DCS codes of your group and turn on the squelch. By setting the level too high, you may not receive the weak signals; while by setting it too low you may receive noises or undesired signals.
NOTE: This transceiver has 10 (0-9) available levels: 0 means that the Squelch is turned on. From level 1 to level 9 you will have different levels of noise reduction. The higher is the level, the louder will be the Squelch.
The steps for setting the squelch level are as follows:
1> Press the [MENU] key to enter the main menu, and press the [+UP]/[-DOWN] key to enter the MENU 03.
2> Press [MENU] key again to enter the SQL menu;
3> Press [+UP]/[-DOWN] key to select the squelch level, select the range 0, 1-9
4> Press [MENU] key to confirm;
5> Press [PTT] or [A/B] key to exit the menu mode.
Retevis RB27 GMRS Farm radio has been widely used in various scenes of agriculture since its market launch.
