■ Your first contact

Now that you have your IC-208H installed in your car or
shack, you are probably excited to get on the air. We would
like to take you through a few basic operation steps to make
your first “On The Air” an enjoyable experience.

■ Squelch attenuator

The transceiver has an RF attenuator related to the squelch
level setting. Approx. 10 dB attenuation is obtained at maxi­mum setting.
The squelch attenuator allows you to set a minimum signal
level needed to open the squelch. The attenuator function can
be deactivated in initial set mode.

➥ Rotate [SQL] clockwise past the 12 o ’clock position to ac-

tivate the squelch attenuator.

• Attenuation level can be adjusted up to 10 dB (approx.) between
12 o’clock and fully clockwise position.

• When setting the squelch from the microphone, a level greater
than ‘19’ activates the squelch attenuator.

NOTE: The squelch attenuator functions even when the
monitor function is in use. Thus set [SQL] control within 10
to 12 o’clock position is recommended when using the
monitor function.

IMPORTANT! (for 55/50 W transmission):

The IC-208H is equipped with protection circuit to protect
the power amplifier circuit from high SWR

(Standing Wave

Ratio) and temperature. When a high SWR antenna or no

antenna is connected, or when the transceiver temperature
becomes extremely high, the transceiver reduces transmit
output power to 15 W (approx.) automatically.

REPEATER OPERATION

4

Repeaters allow you to extend the operational range of your
radio because a repeater has much higher output power than
the typical transceiver.

Normally, a repeater has independent frequencies for each
receiver and transmitter.
A subaudible tone may also be required to access a repeater.

Reference amateur radio hand books and local ham maga­zines for details of local repeaters such as repeater input/out­put frequencies and locations.

• Repeater operation flow chart

• The IC-208H USA version has the auto repeater function. Thus the
steps 3 and 4 may not be necessary, depending on the setting.

• Repeater settings can be stored into a memory channel.

Step 3:

Set the duplex (shifting) direction (– duplex or +duplex).

- Set the offset frequency (shifting value), if required.

Step 4:

Set the subaudible tone (repeater tone) encoder function ON.

- Set the subaudible tone frequency, if required.

Step 1:

Set the desired band to operate the repeater.

Step 2:

Set the desired receive frequency (repeater output frequency).

r Adjust the TNC frequency deviation if necessary.

• When using a deviation meter:

Adjust the output of the TNC so that frequency deviation
is in the range ± 3 to ±4 kHz.

• When NOT using a deviation meter:

A receiver or transceiver is needed to monitor the trans­mission—compare the received audio output level when
receiving a TNC modulated signal with high level voice
signals using the microphone. Then adjust the TNC mod­ulated signal to a lower level than the voice modulated
signal.

When setting data transmission speed to 9600 bps, the data
signal coming from the TNC is applied exclusively to the in­ternal limiter circuitry to automatically maintain band width.

NEVER apply data levels from the TNC of over the accept­able level below, otherwise the transceiver will not be able to
maintain the band width and may possibly interfere with other
stations.

1. When using a level meter or synchroscope, adjust the
TX audio output level (DATA IN level) from the TNC as
follows.

2 Vp-p (1 Vrms) : recommended level
1 Vp-p–3 Vp-p (0.5–1.5 Vrms) : acceptable level

2. When NOT using a measuring device.

q Connect the transceiver to a TNC.
w Enter a test mode (“CAL,” etc.) on the TNC, then trans-

mit some test data.

e When the transceiver fails to transmit the test data or

transmits sporadically (TX indicator doesn’t appear or
flashes):

- Decrease the TNC output level until the transmit indi­cator lights continuously.

When transmission is not successful even though the

TX indicator lights continuously:

- Increase the TNC output level.
