The purpose of the Squelch is to mute the speaker when no signals are present. With the squelch level correctly set, you will hear sound only while actually receiving signals. The higher the selected squelch level, the stronger the signals must be to receive. The appropriate squelch level depends on the ambient RF noise conditions.

Turn the SQL control when there are no signals present to select the squelch level at which the background noise is just eliminated; the green TX-RX LED will turn off. Many ham operators prefer leaving the SQL control fully counterclockwise unless operating on a full-carrier mode such as FM. The squelch level for the transceiver is preset at the factory to approximately the 9 o’clock position for FM and 11 o’clock for SSB and AM.

The multi-function meter measures the parameters in the table below. The S-meter and FILTER scales appears when the transceiver is in receive mode, and the PWR meter appears when it is in transmit mode. Each press of [METER (DRV)] cycles between the ALC, COMP, and SWR meters. Peak readings for the S-meter, ALC, SWR, COMP, and PWR functions are held momentarily.

Turn the Tuning control clockwise or press Mic [UP to increase the frequency. Turn the Tuning control counterclockwise or press Mic [DWN] to decrease the frequency.

You may prefer directly entering a frequency using the numeric keypad if the desired frequency is far from the current frequency. Press [ENT], then press the numeric keys as necessary. For details, refer to “Direct Frequency Entry” {page 28}.

Note:

XThe COMP meter functions only when the Speech Processor is ON for SSB, FM, or AM mode.

XPeak Hold readings cannot be deactivated.

XThe S-meter responds differently in FM mode, compared to other modes. This is not a malfunction.
