RECEIVE AND TRANSMIT

CW operation

The transceiver has the following CW keying features
selectable in set mode as described on page 15.

Full break-in 

(receiving is possible while transmitting)

Delay keying 

(automatic transmission with keying)

Off 

(manual transmission is necessary before keying)

Connect a CW keyer or an external electronic
keyer to the ACC(1) socket as shown at right.

Select the desired channel to operate CW mode.

When the selected channel is not in A1A mode,
push [MODE] one or more times to select “A1A.”

Operate the CW keyer to transmit a CW signal.

NOTE:

CW mode is not available in some ver-

sions and CW narrow can be selected in set mode
(p. 14) when an optional filter is installed (already
built-in to the GMDSS versions).

FSK operation

The transceiver has FSK and J2B modes for FSK op-
eration—use FSK when using the built-in oscillator;
use J2B when using an AFSK terminal unit.

Connect an FSK terminal unit as shown at right.

Select the desired channel.

• FSK ITU channel group, ch 4001 to ch 25040, are avail-

able depending on version.

Push [MODE] one or more times to select the type
of emission, “FSK” or “J2B.”

Operate the FSK terminal unit.

NOTE:

FSK shift frequency and FSK polarity can be
adjusted in set mode (p. 14).

Some transceivers my operate 1.7 kHz higher
than the IC-M710RT’s J2B mode even when
the same displayed frequencies are in use.

Cross channel operation*

Cross channel operation is available with some ver-
sions to operate different channels for receive and
transmit.

Select the desired channel for receive.

• ITU simplex channels cannot be used.

Push [TX], then select the desired channel for
transmit.

• “

$

” flashes after pushing [TX].

Push [TX] again to stop the blinking.

Operate the transceiver normally.

Change the channel to clear the cross channel set-
ting.

*This function is available for Europe versions only.
