Thank you for choosing this KENWOOD TH-F7A
transceiver. It has been developed by a team of
engineers determined to continue the tradition of
excellence and innovation in KENWOOD
transceivers.
First, don’t let the size fool you. This small FM
portable transceiver features 2 m and 70 cm amateur
radio band operation plus another all-mode 100 kHz
to 1.3 GHz receiver (SSB and CW are up to 470
MHz). In the meantime, as you learn how to use this
transceiver, you will also find that KENWOOD is
pursuing “user friendliness”. For example, each time
you change the Menu No. in Menu mode, you will see
a text message on the display that lets you know
what you are configuring.
Though user friendly, this transceiver is technically
sophisticated and some features may be new to you.
Consider this manual to be a personal tutorial from
the designers. Allow the manual to guide you through
the learning process now, then act as a reference in
the coming years.

Repeaters, which are often installed and maintained
by radio clubs, are usually located on mountain tops
or other elevated locations. Generally they operate at
higher ERP (Effective Radiated Power) than a typical
station. This combination of elevation and high ERP
allows communications over much greater distances
than communications without using repeaters.
Most repeaters use a receive and transmit frequency
pair with a standard or non-standard offset (odd-split).
In addition, some repeaters must receive a tone from
the transceiver to allow it to access. For details,
consult your local repeater reference.

◆ Pressing the PTT switch causes “ ” icon to quit blinking.
◆ ASC can be activated while operating in Simplex mode.
However, it does not change the TX/ RX frequencies.
◆ ASC does not function while scanning.
◆ Activating ASC while using Reverse switches Reverse OFF.
◆ If you recall a memory channel or the Call channel that
contains a Reverse ON status, ASC is switched OFF.
◆ ASC causes received audio to be momentarily intermitted
every 3 seconds.
◆ ASC does not function when the band is not selected for
operation.
Note: Some repeaters do not re-transmit the access tone in the
downlink signal. In this case, check the other station’s uplink
signal to detect the repeater access tone.

MEMORY CHANNELS
In memory channels, you can store frequencies and
related data that you often use. Then you need not
reprogram those data every time. You can quickly
recall a programmed channel through simple
operation. A total of 400 memory channels are
available for storing the frequencies, modes and
other operating conditions of the A and B-bands.
SIMPLEX & REPEATER OR
ODD-SPLIT MEMORY CHANNEL?
You can use each memory channel as a simplex &
repeater channel or an odd-split channel. Store only
one frequency to use as a simplex & repeater
channel or two separate frequencies to use as an
odd-split channel. Select either application for each
channel depending on the operations you have in
mind.
Simplex & repeater channels allow:
•Simplex frequency operation
•Repeater operation with a standard offset
(if an offset direction is stored)
Odd-split channels allow:
•Repeater operation with a non-standard offset

NORMAL SCAN
When you are operating the transceiver in VFO mode,
3 types of scanning are available: Band Scan,
Program Scan, and MHz Scan.
BAND SCAN
The transceiver scans the entire band of the
frequency you selected. For example, if you are
operating and receiving at 144.525 MHz on the
A-band, it scans all the frequencies available for the
2 m band. (Refer to receiver VFO frequency range
in the specifications {page 54}.) When the current
VFO receive frequency is outside of the Program
Scan frequency range {page 23}, the transceiver

Usually you can communicate with other amateur
radio stations using A-band frequencies for receiving
and transmitting. This transceiver also features
another receiver in addition to the A-band transceiver.
The frequency for the B-band appears on the bottom
part of the display. Although the A-band transceiver
covers only the 2 m/ 70 cm amateur radio bands in
FM mode, the B-band receiver can receive signals
from 100 kHz to 470 MHz in SSB, CW, FM, or AM
mode, and from 470 MHz to 1.3 GHz in FM or AM
mode.
In this way, you can monitor 2 different frequencies at
the same time. For example, you can listen to a local
FM broadcasting station on the B-band while you are
monitoring your club channel on the A-band.
If one of the A-band amateur radio bands is selected
for the B-band receiver in FM mode, you can also
transmit on the B-band frequency.
B-BAND FREQUENCY
Since the B-band frequency coverage is so wide, the
default frequency band, mode, and frequency step
size are preprogrammed as shown below.
1 Press [A/B] to select B-band.
•The “s” icon moves, indicating which band is
currently selected for operation.
2 Press [BAND] until the desired frequency band
appears.
•Each time you press [BAND], the frequency
band cycles from the last band you selected to
the upper band frequency. When it reaches
the 23 cm band, it returns to the AM band.
•You can also press [ ]/ [ ] to select your
desired band in VFO mode {page 7}.
3 Tu rn the Tuning control or press [ ]/ [ ] to tune to
a desired frequency.
Note: You can also select one of the amateur radio bands to
transmit on the B-band frequency. However, you must be

14 TROUBLESHOOTING
TROUBLESHOOTING
The problems described in the following table are commonly encountered operational malfunctions. These types
of difficulties are usually caused by improper hook-up, accidental incorrect control settings, or operator error due
to incomplete programming. These problems are usually not caused by circuit failure. Please review this table,
and the appropriate section(s) of this instruction manual, before assuming your transceiver is defective.
Note: Placing powered PC peripherals near this transceiver may cause noise in the transceiver.
If your transceiver seems to be malfunctioning,
resetting the microprocessor may solve the problem.
The following 3 reset modes are available. When
performing the reset, you may lose memory data and
stored information. Back up or write down important
data before performing the reset.
INITIAL SETTINGS
For each VFO, the factory defaults for the operating
frequency and mode are as follows.
•A-band: 144.000 MHz/ FM
•B-band: 430.000 MHz/ FM
The Memory channels have no data stored. Refer to
pages 19 and 20 for the Call Channels and
Information Channels default values.
VFO RESET
This resets the transceiver parameters excluding the
Menu contents and Memory channel contents.
Note: Menu No. 4 (PROG VFO) and No. 6 (OFFSET) return to
the factory default values.
4 Press [ ] or [MNU] to proceed.
•If you press any keys, other than [LAMP] and
[MONI], the transceiver exits the reset mode.
•A reset confirmation message appears.
5 Press [ ] or [MNU] to reset the transceiver.
•If you press any keys, other than [LAMP] and
[MONI], the transceiver exits the reset mode.
MENU RESET
This resets the parameters only in the Menu items to
factory default values.
FULL RESET
This resets all transceiver parameters to the factory
default values.
PERFORMING RESET
There are 2 ways to enter the reset mode selection.
However, the transceiver must be configured to the
Lock function OFF {page 38}.
When the transceiver is turned OFF:
1 Press [F]+[ ] (POWER).
•All indicators are lit.
2 Release [F].
•Proceed to step 3 {below}.
From the Menu:

14 TROUBLESHOOTING
OPERATION NOTICES
The transceiver has been designed and engineered
to avoid possible hardware glitches. However, you
may notice the following symptoms when you operate
the transceiver. These symptoms are not
malfunctions.
OPERATING VOLTAGE
As stated in “SPECIFICATIONS” {page 53}, this
transceiver operates on a DC voltage from 5.5 V ~
7.5 V DC (battery terminal) or 12.0 V ~ 16.0 V DC
(DC IN jack). If you find that the transceiver cannot
be switched ON, or “VOLTAGE ERROR” appears, the
supplied power source may be outside of the
specified range.
In such a case, remove the DC power cable from the
transceiver immediately and confirm that the supplied
voltage is within the specified range.
If you are using a variable DC power supply to
operate the transceiver, adjust the DC power supply
voltage to 12.0 V DC. Considering the output power
efficiency and thermal characteristics of the
transceiver, this is the optimal voltage to operate the
transceiver.
TUNING IN SSB/ CW MODE
The transceiver uses a general purpose IF filter to
receive signals in LSB, USB, CW and AM modes.
So, when you receive signals in LSB or USB mode,
the opposite side band signal is not fully attenuated.
At the same time, since the same filter is used for CW
reception, you may have difficulties seperating the
CW signal from other signals in the crowded band.
To best tune in to a SSB signal, follow the instruction
below.
BEAT AND NOISE
When you have the same 2 m and 70 cm band
frequencies for both A and B-band receivers, the
Visual Scan may indicate the signals on the bargraph display even if no signal is monitored on the
A-band receiver. This error occurs due to the
internal spurious harmonics that are generated by
the B-band-receiver. Refer to “INTERNAL BEATS”
{below} for the frequencies.
You may also hear some noise in the receiving signal
in the following cases.
•You perform any scan on the other receiver.
•You perform the Visual Scan on the B-band
receiver.
TRANSMISSION
If you continuously transmit for more than 3 minutes
at high power (5 W), the transceiver becomes warm.
If you continue or repeat the transmission before the
transceiver cools down, the thermal protector
automatically decreases the output power to 0.5 W.
“H” also blinks at the same time. If this happens, let
the transceiver cool down for a while before
transmitting again.
If you continuously transmit for an extended period at
high power (5 W) using the DC IN jack, the
transceiver becomes warm. If you continue or repeat
the transmission before the transceiver cools down,
the thermal protector automatically decreases the
output power to 0.5 W. “H” will blink at this time. For
the 70 cm band, the thermal protector activates in
about 2 ~ 5 minutes at high power, depending on the
ambient temperature. In these cases, let the
transceiver cool down for a while or use the “L” (low
power) position before transmitting again.
When you receive signals in USB mode:
1 Tu rn the Fine Tuning function ON {page 33}.
2 Tune to the target signal while starting at a lower
frequency, using the Tuning control.
When you receive signals in LSB mode:
1 Tu rn the Fine Tuning function ON {page 33}.
2 Tune to the target signal while starting at a higher
frequency, using the Tuning control.
RECEIVING IN AM BAND
If you receive a weak signal in AM band, you may
notice a high pitched squealing noise in the
background. This noise is generated by the internal
DC/DC converter and it cannot be removed.
RECEIVING SIGNALS IN CITIES
When you receive signals in cities, the receiver’s entire
S-meter may light up without receiving any strong
signals. This happens when the RF amplifier in the
receiver is overloaded by strong interference signals
that are nearby. In this case, turn the Attenuator
function ON {page 34} to reduce the interference
signal level. You may further have to adjust the
volume level while receiving the target signal.
SUPPLIED ANTENNA
The supplied antenna is designed to give you the
best transmission and reception performance on the
2 m and 70 cm amateur radio bands. So, it may not
be suitable for the frequency that you want to receive.
Use an appropriate antenna for the frequency if the
sensitivity is low.
INTERNAL BEATS
If one of the formulas on the next page is true, the
S-meter moves without receiving any signals or you
cannot receive any signals. This is inevitable when
you use superheterodyne receivers.
