Function Configuration Screens and Bandscope Screen

Although there is no display on the lower portion of the main screen by default, this is where various screens are
displayed, such as the Bandscope screen, Waterfall screen, and the RTTY/PSK Encode Decode screen. To
configure the desired function, the screen corresponding to that function appears here.
Pressing the [EXTEND] (F) key while the RTTY/PSK Encode Decode screen or the Memory Channel List screen is
open extends the display area.
Pressing the [SCP] key even while the RTTY/PSK Encode Decode screen or other function configuration screen is
open displays a compressed version of the Bandscope screen, allowing you to view the radio wave status at any time.

Touch Screen

During operation, a signal drawing a noticeable event may appear on the Bandscope screen or the Waterfall screen.
To receive such a noticeable signal, simply touch the portion, where the signal appears on the screen quickly transits to
the ambient of the target signal, allowing you to do the fine tuning of the frequency by rotating the Tuning knob. In CW
mode, long touching of the Waterfall screen starts CW auto tuning, which provides high‑precision tuning. In SSB mode,
to make the tune‑in easier on a point on the screen, the marker position is shifted to the carrier frequency by 500 Hz (the
shift amount can be changed in the menu).
Available touch screens are roughly classified into two types: the "Electrostatic Capacity" type and the "Resistive
Membrane" type. Since the TS‑990S has transmission capability, the resistive membrane types, which appears to not
have much influence by the loop interference is employed.

Sub Screen

The largest aim at placing a sub screen in addition to the main screen is to display the frequency just above the Tuning
(main) knob, facilitating you to view the frequency value. The small‑size display is mounted to minimize the moving
amount of the sight line during operation and achievement of the innovative convenience and comfortable operation.
The sub screen displays the status of signals the TS‑990S is receiving and helps manipulations of the operator. The
sub screen can also display the ΔF value display, enabling you to view the difference between the transmit and receive
frequencies (ΔF), the sub‑scope displaying the audio spectrum by superimposing an audio spectrum on the shape of
the RX filter, and the large‑sized X‑Y monitor and vector scope convenient for tuning while in RTTY and PSK modes. In
place of these scope displays, the sub screen can also display a mechanical dial and enlarged values of the operating
frequencies.
