SQL (Squelch): Sets the threshold for signal reception. A setting of 3 or 5 is usually ideal for blocking out background static.STEP: Sets the frequency increments when scanning (5K, 6.25K, 10K, etc.).TXP (Transmit Power): Allows you to toggle between HIGH and LOW power to conserve battery life.TDR (Dual Watch): When enabled, this allows the radio to monitor two different frequencies simultaneously.
