Rf Gain And Sql Level - Icom IC-9700 Basic Manual

RF gain and SQL level

Rotate (outer) to adjust the RF gain and
AF RF/SQL
SQL level.
By default, rotating left (when set to the 12 o'clock
position) adjusts the RF gain, and rotating right
adjusts the squelch level, as described below.

RF gain
Adjust the RF gain to decrease the noise received
from a nearby strong station.
• Rotate counterclockwise to reduce the RF gain, which
reduces the receive sensitivity. "RFG" appears when
is set to the counterclockwise from the 11 o'clock
AF RF/SQL
position. "RFG" indicates that the RF gain is reduced.
L If a strong signal is received and "OVF" (Overflow)
appears, reduce the RF gain until "OVF" disappears.
SQL level
There are 2 types of SQL levels, depending on the
operating mode.
• Noise squelch
Rotate the (outer) until the noise just
AF RF/SQL
disappears and the TX/RX indicator goes OFF.
• S-meter squelch
The S-meter squelch disables the audio output from
the speaker or headphones when the received signal is
weaker than the specified S-meter squelch level.
Rotate the clockwise from the 12 o'clock
AF RF/SQL
position to increase the S-meter threshold level.

Adjusting the transmit output
power
Before transmitting, monitor your selected operating
frequency to make sure you do not cause interference to other
stations on the same frequency. It is good amateur practice
to listen first, and then, even if nothing is heard, ask if the
frequency in use once or twice, before you start operating.
D Adjusting the transmit output power
1. Select the operating mode. (p. 3-3) (Example: USB)
2. Touch the meter to display the Po meter. (p. 3-11)
3. Open the Multi-function menu.
4. Push
TRANSMIT
• The Po meter level changes according
to your voice level in the SSB mode.
• The TX/RX indicator lights red and
is displayed.
5. Touch "RF POWER."
6. Adjust the transmit output power to between 0 and
100%.
• The Po meter displays the RF output power in a
percentage. It becomes the S-meter while receiving.
7. Push
TRANSMIT
• Returns to receive.
Transmit Power Limit function
The Transmit Power Limit function limits the output
power to the preset level for each band.
1. On the FUNCTION set screen, touch [TX PWR LIMIT].
• Each touch turns the function ON or OFF.
2. Touch [TX PWR LIMIT] for 1 second.
3. Rotate to set the maximum transmit power.
