Rtty And Psk Operation Without Using A Pc - Kenwood TS-990S In-Depth Manual

Below the transversed dials and an S‑meter, the Bandscope screen and Recording Audio File screen open in the
same manner as in normal operations. Meter band choice, useful for reception of short wave broadcasting, and a
recorder can also be used.
Note:
◆ The pre‑determined meter bands in SWL mode are refined to be different from commonly used meter bands and to widely
cover the broadcasting bands in every region.
◆ The TS‑990S cannot transmit in SWL mode.

RTTY and PSK Operation without using a PC

The TS‑990S is equipped with an internal demodulator and decoder (conformed to 170 Hz shift only), allowing operation
in RTTY and PSK modes without using a PC. For operation in PSK mode, in addition to PSK31, which many have been
familiar with for decades, PSK63 (BPSK only), which is becoming popular operation in these years, is implemented.
With a USB keyboard connected to the TS‑990S, efficient and comfortable operations can be secured. Needless to say,
keying from an external RTTY device through the RTTY terminal is allowed.
In FSK mode or PSK mode, the encode/decode screen shows a dedicated audio FFT scope. The bands of the audio
FFT scope are specially designed to provide an enlarged view of a signal close the indication displayed. If the target
signal is masked by different signals, the status of the target signal can still be observed visually.
