Depending on the operational status, the bandscope can be used in either of two modes: Center mode and Fixed mode.
In Center mode, the frequency spectrum is displayed placing the receive frequency at the screen center at all times. This
is useful to view the adjacent frequencies of the received signal.
In Fixed mode, the range of the frequency spectrum display is fixed by band. This is useful to monitor the status through
the band. The lower‑limit frequency and the upper‑limit frequency of the display ranges of the bands can be configured
respectively in the menu. Bands are partitioned by amateur band in the range from 1.8 to 50 MHz bands, and the LF
band and MF band are individually available.
The following auxiliary functions are convenient to observe signals:
● Adjusting the Reference Level
If there is substantial noise or if it is not easy to distinguish a target signal and noise, adjusting the reference level of the
bandscope will facilitate you to distinguish the target signal easily.
Note:
◆ If a target signal is indistinguishable in the Bandscope screen due to strong adjacent frequency signals or within the band,
press the [ATT] (F5) key to select an adequate attenuator for the bandscope.
● Changing the Falling Speed of Waterfall Display
Reducing the falling speed of a fast moving waterfall display allows the waterfall waveform to be more easily
recognizable.
● Changing the Receive Frequency with a Touch
When a target signal is detected in the Bandscope screen or the Waterfall screen, touching the main screen directly
with your finger, prior to rotating the Tuning knob, near the target signal can instantly enable QSY (access) to near the
target frequency. In CW mode, long touching a point on the main screen automatically activates CW auto tuning after the
frequency is placed close to the target signal, allowing more accurate tuning.
