Using the Twin PBT
SSB, CW, RTTY and AM modes
In general, the Twin PBT (Passband Tuning)
electronically narrows the IF passband width by
shifting the IF frequency to slightly outside of the IF
ilter passband, to reject interference. The IC-7300
uses DSP for the PBT function.
You can narrow the IF passband width by rotating
both TWIN PBT CLR inner (PBT1) and outer (PBT2) to
the opposite direction from each other.
LYou can see the nearby signal using the Spectrum Scope
(Section 5).
1. Rotate TWIN PBT CLR inner (PBT1) and outer
(PBT2) to the opposite direction from each other.
2. Touch the Filter icon for 1 second to display the
current passband width and shift frequency.

LInformation
• Match both the TWIN PBT CLR (inner) (PBT1) and

• If you rotate the control too much, the received
audio may not be heard because the passband
width is too narrow.
• Displays the passband width and shift value.
• A dot is displayed above the passband width when
you rotate TWIN PBT CLR .
• Hold down TWIN PBT CLR for 1 second to clear the

• The PBT is adjustable in 50 Hz steps in the SSB,
CW, and RTTY modes, and 200 Hz in the AM
mode. In this case, the center shift value changes
in 25 Hz steps in the SSB, CW, and RTTY modes,
and 100 Hz in the AM mode.
• Rotating both the inner and outer controls to the

Noise Blanker
• SHARP
This selection is to emphasize the passband width of
the ilter. The ilter has an almost ideal shape factor.
Signals of the out of passband are extremely iltered
out and it gives you better audio quality.
The Noise blanker eliminates pulse-type noise such
as the noise from car ignitions.
The Noise blanker cannot be used in the FM mode.
Push
• SOFT
The ilter shoulders are roundly formed as in analog
ilters. This decreases noise components in the
high and low frequencies of the ilter passband
and increases the S/N of the target signal. These
characteristics play an effective role in picking up
very weak signals in the 50 MHz band, for example.
The shape factor is kept, and the sharpness of the
bandpass is excellent.

ANTENNA TUNER OPERATION
About the internal antenna tuner
Internal antenna tuner operation
The internal automatic antenna tuner automatically
matches the transceiver to the antenna within the
range of 16.7 ~ 150 Ω (SWR of less than 3:1).
After the tuner matches an antenna, the latching relay
combinations are memorized as a preset point for
each frequency range (100 kHz steps). Therefore,
when you change the frequency range, the latching
relay combinations are automatically preset to the
memorized point for fast tuning.
1. Push
tuner.
TUNER
to turn ON the internal antenna
• “TUNE” is displayed when the tuner is ON.
2. Tune the antenna.
LTo tune the antenna, see “Manual tuning” or “PTT
Tuner start” below.
D Manual tuning
You can manually tune the antenna before transmitting
for the irst time.
1. Hold down TUNER for 1 second to start manual
tuning.
• When you install a new antenna, or you want to
change the antenna settings, you can clear the all
of the internal antenna tuner preset points with the
“<>” item on the TUNER set
screen. (p. 8-3)
MENU » SET > Function > Tuner >
<>
• The tuner reduces the SWR to less than 1.5:1 after
2~3 seconds of tuning.
LWhile tuning, a side tone is heard and “TUNE” blinks
red.
2. After tuning, “TUNE” is displayed.
LIf the tuner cannot reduce the SWR to less than 1.5:1
after 20 seconds, tuning stops and “TUNE” goes out.
• You can select whether or not to save the internal
antenna tuner’s status after pushing TUNER on each
band in the “[TUNER] Switch” item on the TUNER
set screen. (p. 8-3)
MENU » SET > Function > Tuner >
[TUNER] Switch
D PTT Tuner start
The tuner is always activated when PTT is pushed
after the frequency is changed (more than 1% from
last-tuned frequency). This function tunes the antenna
for the irst transmission on a new frequency.
LThis function can be turned ON in the “PTT Start”
item of the TUNER set screen. (p. 8-3)
MENU » SET > Function > Tuner > PTT Start
NOTE: When the transceiver receives a strong physical
shock, the internal latching relays may be returned to an
unlatched condition. In that case, push TUNER to turn
OFF the tuner, then turn ON again to reset the all latching
relays.
NOTE:
• If the SWR is higher than about 1.5:1 when tuning more
than 100 kHz on an antenna’s preset point, hold down
[TUNER] for 1 second to start manual tuning.
• If you transmit into a high SWR, “TUNE” may blink. In that
case, hold down TUNER for 1 second to manually tune.
If the tuner cannot tune the antenna
• Repeat manual tuning several times.
• Even if the tuner cannot tune the antenna on the irst
tuning, it may success at the second tuning.
• Some antennas, especially for the low bands, have a
narrow bandwidth. These antennas may not tune at
the edge of their bandwidth, therefore, tune such an
antenna as follows:
(Example):
Suppose you have an antenna which has an SWR of
1.5:1 at 3.55 MHz and an SWR of 3:1 at 3.8 MHz.
1. Set 3.55 MHz, and hold down TUNER for 1
second to start manual tuning.
2. Set 3.80 MHz, and hold down TUNER for 1
second to start manual tuning.

or damage the transceiver. To prevent this, we recommend
adding a switching diode, such as an 1SS133, on the load
side of the circuit to absorb the counter-electromotive force.
When the diode is added, a delay in relay switching may
occur. Be sure to check its switching action before operating.

INSTALLATION NOTES
For amateur base station installations it is recommended
that the forward clearance in front of the antenna array is
calculated relative to the EIRP (Effective Isotropic Radiated
Power). The clearance height below the antenna array can
be determined in most cases from the RF power at the
antenna input terminals.
In all cases any possible risk depends on the transmitter
being activated for long periods. (actual recommendation
limits are speciied as an average during 6 minutes)
Normally the transmitter is not active for long periods of
time. Some radio licenses will require that a timer circuit
automatically cuts the transmitter after 1–2 minutes etc.
As different exposure limits have been recommended for
different frequencies, a relative table shows a guideline for
installation considerations.
Similarly some types of emission, i.e., SSB, CW, AM etc.
have a lower ‘average’ output power and the assessed risk
is even lower.
• List of Country codes (ISO 3166-1)
Below 30 MHz, the recommended limits are speciied in
terms of V/m or A/m ields as they are likely to fall within the
near-ield region. Similarly, the antennas may be physically
short in terms of electrical length and that the installation will
require some antenna matching device which can create
local, high intensity magnetic ields. Analysis of such MF
installations is best considered in association with published
guidance notes such as the FCC OET Bulletin 65 Edition
97-01 and its annexes relative to amateur transmitter
installations. The EC recommended limits are almost
identical to the FCC speciied ‘uncontrolled’ limits and tables

• Typical amateur radio installation
Exposure distance assumes that the predominant radiation
pattern is forward and that radiation vertically downwards
is at unity gain (sidelobe suppression is equal to main lobe
gain). This is true of almost every gain antenna today.
Exposed persons are assumed to be beneath the antenna
array and have a typical height of 1.8 m.
The igures assume the worst case emission of a constant
carrier.
