PSK Decode
The received PSK signal is decoded and presented in text on the TFT display.
Cross talk, noise, phasing, etc., may cause scrambled characters to be displayed.
1. For PSK operation, set the Menu items as indicated in the below chart.
Setting Menu Available Values (Bold is the default)
RADIO SETTING
→ MODE PSK/DATA
→ DATA MODE SOURCE
MIC DATA is input from the MIC jack on the front panel.
REAR DATA is input from the USB jack or RTTY/DATA jack on the rear panel.
RADIO SETTING
→ MODE PSK/DATA
→ REAR SELECT
DATA
Inputs the transmission data from the RTTY/DATA jack (pin 1) on the rear
panel.
USB Inputs the transmission data from the USB Jack on the rear panel.
RADIO SETTING
→ MODE PSK/DATA
→ RPTT SELECT
DAKY
Controls the DATA transmit signal from the RTTY/DATA jack (pin 4) on the
rear panel.
RTS/DTR
Controls the DATA transmit signal from the USB virtual COM/RTS or DTR
ports.
RADIO SETTING
→ ENCDEC PSK
→ PSK MODE
BPSK THIS is the standard mode. Normally use BPSK mode.
QPSK QPSK incorporates error correction function.
1. Set the operating mode to PSK.
Align the peak of the received signal with the
mark frequency and shift frequency marker of
the TFT screen.
2. Press the [FUNC] knob.
3. Touch “DECODE”.
The PSK DECODE screen will appear, and
the decoded text is displayed on the screen.

• Set the data output level for data communi-
cations using Menu item “DATA OUT LEVEL”
(page 91).
• When a signal is input, it can be automatically
sent using Menu item “VOX SELECT” (page
104).
• Set data input VOX gain in VOX operation
for data communications using Menu item
“DATA VOX GAIN” (page 104).
When a PSK signal is not being received,
scrambled characters may be displayed due to
noise and band clutter. The threshold level can
be adjusted so the scrambled text is not dis-
played.
Threshold Level Adjustment
1. Touch [DEC LVL] on the lower left side of the PSK
decode screen.
2. Rotate the [FUNC] knob, and adjust the threshold
level (between 0 and 100) so scrambled characters
are not displayed.
Note that text will no longer be displayed for weak
signals if the level is increased too much.
3. The setting is concluded when 1 second have
elapsed after making the level adjustment.
