5.9 Morse Code Decoder

TS-590SG supports Morse code decoding function. This function can be used in CW mode.
It is easy to use. Press the [DATA] key to turn on/off the Morse code decoder. When it is turned on, the decoded characters
scroll on the 13-segment display screen.
Depending on the signal condition, the decoder may not be able to distinguish between signal and noise, and the code
may not be correctly decoded. In that case, it may be effective to adjust the threshold level.
To adjust the threshold level, press and hold the [DATA] key. The number that blinks is the current threshold level. Change
the level by turning the MULTI/CH knob. The variable range of the threshold level is 1 to 30. For the range of 11 to 30, the
level is also displayed on the lower meter. (The threshold level can be adjusted in the range of 1 to 10 when the S meter
is not deflected and in the range of 11 to 30 when the S meter is deflected.)
If deflection in the S meter is caused by the background noise, adjust the level such that the threshold level of the lower
meter slightly exceeds the S meter deflection caused by the noise.
If no deflection is caused by the background noise, adjust the level between 1 to 10 while checking the decoding status.
(If noise is observed, it will be effective to narrow the passband width for reception.)
The keying speed is automatically tracked according to the signal of the station at the other end. However, in the event of
huge fluctuations, tracking of signals that deviate significantly from the standard timing is not possible. (When receiving
CW signals with different speeds, tracking may fail temporarily.)
If the space between the characters of the Morse code received is small, decoding may fail.
The transceiver unit supports display up to 8 characters. You can view the full decoded message using the ARCP-590G.
Caution:
◆ This function can only decode Morse signal of the receive signal. It does not decode and display Morse signal sent from this
transceiver.

5.10 Double Function Keys and Hold Time Selection

Just like the TS-480HX/SAT, TS-590S/SG employs double function keys to activate different functions by holding down
a key. This is meant to make operation easier than in the system requiring one to push a function key first before hitting
another key to invoke the desired function.
Since for most of the keys, functions related to the original functions of the keys are assigned, they can be used intuitively.
Examples: NB key and variable NB level, the NOTCH key and NOTCH WIDTH selection, etc.
Additionally, the hold time to activate another function can be switched in three stages. By default about 0.5 seconds is
selected, but you can switch between about 0.2 seconds, and about 1 second as necessary.

5.11 Mode Selection of Built-in Electronic Keyer

The transceivers in the previous generations were equipped with an electronic keyer in which dots and dashes are always
memorized for output. On the TS-590S/SG, we have employed an electronic keyer which allows a user to select either of
the conventional keyers, which is called Mode B , or a newly adopted Mode A which has different memory timings. If
you experience the problem of producing an extra dot or dash in Mode B , try Mode A and you may find you are able to
send more accurately with greater ease.
