though the actual tone you hear is not changing.

When operating on the FM mode, rotate the [RF/SQL] (Squelch) knob clockwise to the point where the background noise is just silenced. This is the point of maximum sensitivity to weak signals. Excessive advancement of the [RF/SQL] knob will decrease the ability of the reciever to detect weak signals.
You may switch the [RF/SQL] knob from the RF Gain Function to the Squelch Function via Menu item "038 RF/SQL VR".

8.    Rotate the Main Tuning Dial knob to tune around the bank, and begin normal operation.

ADVICE:

Clockwise rotation of the Main Tuning Dial knob increases the operating frequency, one "step" of the synthesizer at at time; similarly, counter-clockwise rotation of the Main Tuning Dial knob will decrease the frequency. Two settings, one "normal" and one "fast", are available for each operating mode. Pressing the [FAST] button engages the "Fast" tuning selection (see chart below).


The tuning steps for the Main Tuning Dial knob are set, at the factory, to 10 Hz (SSB, CW, RTTY, DATA) and 100 Hz (AM/FM) per step. Via Menu itams "151 CW DIAL STEP" to "155 SSB DIAL STEP", however, you may change these settings from 10 Hz to 1 or 5 Hz (SSB, CW,RTTY, DATA) and 100 Hz to10 Hz (AM/FM) instead.

If you want to effect rapid frequency change, there are several techniques available:

  • Direct keyboard entry of the frequency.

  • Use the [VFO-B/CLAR] knob to tune in 1 MHz steps.

  • Use the microphone's [UP]/[DWN] scanning keys, if your microphonedis so equiped.
