WATERFALL
In linking with the audio FFT scope, transition of the
frequency components contained in the received audio
signal can be displayed.
X-Y SCOPE ±SUB-SCREEN²
The tuned status of the signal in RTTY (FSK) mode is
displayed as a cross pattern (90 degrees) on the X-Y
scope. The cross patterns bisect at right angles when the
transceiver is correctly tuned into the signal.
1
Press
[FSK/ PSK/ REV]
to enter RTTY (FSK) mode.
2
Press
[DECODE]
(F3) to open the
RTTY Encode/
Decode
screen.
3
Press
[S.DISP/ SEL]
to display the X-Y Scope.
Note:
The X-Y scope appears only if the
RTTY Encode/Decode
screen
appears on the main screen.
USING THE USB KEYBOARD TO TRANSMIT A
TEXT STRING
You can connect a commercially available USB keyboard
to the transceiver to enter and transmit a text string.
TRANSMITTING THE ENTERED TEXT STRING AS
ENTERED
[F1]~[F7]
[FSK/PSK/REV]
1
Connect a USB keyboard to the
(USB-A)
connector.
2
Press
[FSK/ PSK/ REV]
to enter RTTY (FSK) mode.
3
Press
[DECODE]
(F3) to open the
RTTY Encode/
Decode
screen.
4
Press
[F12]
on the USB keyboard to start to transmit.
The "BUSY/TX" LED lights red and "ENCODE" appears on
the status bar.
5
Enter the text strings using the USB keyboard.
The entered text string is placed and displayed in the text
string buffer and transmitted as entered.
Each letter in the text string buffer changes its color in
sequence when the letter is transmitted.
Text strings transmitted are displayed in sequence in the
TX and RX Transcript.
6
Press
[F12]
on the USB keyboard to stop transmission.
Note:
If letters not transmitted yet remain in the text string buffer when
[F12]
is pressed at step 6, "WAIT" appears on the status bar.
When the entire text string is transmitted, the transceiver enters the
receive mode and the "BUSY/TX" LED and "WAIT" are unlit.
