CONFIGURATION FOR RTTY ENCODING AND
DECODING
ENABLING THE UOS (UNSHIFT ON SPACE)
If the received RTTY signal contains a space, use this
function to decode the letter next to the space forcibly as a
letter code (alphabetical letter).
In RTTY, the influence of signal strength or noise causes
letter corruption. In order to avoid this problem as much
as possible, the function makes it possible to decode the
letter after the space as a more frequently used letter code
(alphabetical letter).
To receive a test string containing numbers andsymbols
subsequent to a space, you can disable the UOS function.

Menu screen.

box.
4 Press [-] (F4) or [+] (F5) to select "On" or "Off".
The default is "On" (encoding a blank letter). Selecting "Off"
does not allow the transceiver to encode the blank letter.

6 Press [MENU] to exit.
