Multifarious Memory Channels

The TS‑990S is capable of storing up to 120 memory channels within which operation data can be registered. The 120
memory channels are classified into three groups: 00 to 99, P0 to P9, and E0 to E9.
• 00 to 99 (standard memory channels): for storing frequently‑used operation data.
• P0 to P9 (programmable memory channels): for storing frequency ranges of programmable VFOs and programmed scanners.
• E0 to E9 (extended memory channels): for storing those addition to the standard memory channels.

Storing States of Split Operation and Dual Band Reception

Standard memory channels and extended memory channels can be divided into two modes, following the memory
channel registration and recall methods: single memory channel mode and dual memory channel mode.
• Single memory channel mode is used to store frequencies for simplex operation and frequencies for radio broadcasting.
• Dual memory channel mode is used to store frequencies for split operation and frequencies for dual band reception.

Multifarious Functions Supporting the Operator

Frequency Tracking

With frequency tracking enabled, rotating the Tuning (main) knob changes the main band and sub band frequencies
at the same time. Rotating the Tuning (sub) knob changes only the sub band frequency. Rotating the Tuning (main)
knob while the sub band frequency is displaced changes the main band frequency and the sub band frequency
simultaneously, maintaining their frequency spacing.
Frequency tracking can be used to receive both main band and sub band signals with different antennas connected to
the main band and sub band, for instance.

DATA Modes Corresponding to a Variety of Operations

As well as the MIC connector (on the front panel), there are connectors on the rear panel as an audio signal sourcing
path for TX audio signal input. In addition to the USB‑B connector for USB audio signal input from a PC and the ACC2
connector for analog audio signal input, there is the OPTICAL IN connector that enables the signal input from a device
with an optical digital I/O capabilities.
For the transmit trigger, the [PTT] key, [SEND] key, PKS terminal in the ACC2 connector, and the PF key assigned as
DATA SEND can all be used.
In the TS‑990S, the input audio signal to be transmitted can be selected by DATA mode, by viewing a matrix displayed in
the Modulation Source screen.
