7 SCOPE FUNCTIONS

Bandscope

With the signal strength represented on the vertical axis and
frequency on the horizontal axis, the bandscope provides a visual
representation of the condition of the RX frequency band.
• The bandscope of this transceiver comes in the following 3
modes.
Auto Scroll Mode: A mode where the lower and upper
frequency limits of the frequency band to be displayed are fixed,
and the scope range scrolls automatically when the marker
exceeds the lower or upper limit of the scope range.
Fixed mode: A mode where the lower and upper frequency
limits of the frequency band to be displayed are fixed for each
amateur band.
Center mode: A mode where the RX frequency is always at the
center of the horizontal axis.
• By displaying a waterfall below the spectrum scope display, the
RX frequency, surrounding conditions as well as transition in
the signal strength over time can be viewed.
• The vertical axis of the waterfall display represents time while
the horizontal axis represents frequency.
• Signal strength in the waterfall display is represented in a
gradation of color in the order of green to blue (weak), red to
yellow (medium) and white (strong). The amount of color
change with respect to the signal strength can be altered in the
menu. Refer to "Configuring the Gradation of the
(7-5).
• The speed of the waterfall drop can be changed to 4 different
speed levels. Refer to "Configuring the Speed of Waterfall
Drop" (7-2).

scope display is reduced to one-third of the original size.
• The filter passband is constantly represented by a translucent
display in the bandscope.
