Cw Operation; Fsk Operation - Icom IC-M802 Instruction Manual

■ CW operation

The transceiver has the following CW keying fea-
tures selectable in the Set mode, as described on
page 53.
➥ Full break-in (Immediately returns to receive when
you release a key)
➥ Semi break-in (Returns to receive after a preset
delay time has passed after you stop keying.)
➥ OFF
( manual transmission with microphone's [PTT], or
grounding the SEND line of the [ACC] connector
is necessary before keying)
q Connect a CW keyer or an external electronic
keyer to the [ACC] socket, as shown to the right.
w Select the desired channel to operate in the CW mode.
e If the selected channel is not in the A1A (CW) mode,
push [MODE ] several times to select "A1A."
set
r Operate the CW keyer to transmit a CW signal.

■ FSK operation

The transceiver has F1B and J2B modes for FSK op-
eration—, select F1B when using the built-in oscilla-
tor; select J2B when using an AFSK terminal unit.
q Connect an FSK terminal unit to the [ACC] socket
as shown to the right.
w Select the desired channel to operate in the FSK mode.
• FSK ITU channel group, Ch 4001 to Ch 25040, are only
usable when the SITOR CH setting is set to ON. (p. 51)
e Push [MODE ] several times to select F1B or J2B.
set
r Operate using the FSK terminal unit.
NOTE:
➥ FSK tone, shift frequency and FSK polarity can
be adjusted in the initial set mode. (p. 53)
➥ Some transceivers may operate 1.7 kHz higher
than the IC-M802's J2B mode, even when the
same displayed frequencies are is selected.
