OPERATING THROUGH REPEATERS
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.

(DIAGRAM HERE OF 2 CARS USING A REPEATER)

OFFSET PROGRAMMING FLOW

1 Select a band.

2 Select a receive frequency.

3 Select an offset direction.

4 Select an offset frequency. (only when programming odd-split repeater
frequencies)

5 Activate the Tone function. (If necessary)

6 Select a tone frequency. (If necessary)

If you store the above data in a memory channel, you need not
reprogram every time. See "MEMORY CHANNELS" {page 15}.

PROGRAMMING OFFSET

First select an amateur radio repeater downlink frequency on the
A-band or B-band as described in "SELECTING A FREQUENCY" {page
7}.

* Selecting Offset Direction
Select whether the transmit frequency will be higher (+) or lower
(-) than the receive frequency.

Press [F], [REV] to select the offset direction.  "+" or "-"
appears, indicating which offset direction is selected.  To
program -7.6 MHz offset on the TH-F7E (430 MHz only), repeatedly
press [F], [REV] until "(BOX SURROUNDING -) (VISUALLY NO INDICATION)"
appears. If the offset transmit frequency falls outside the allowable
range, transmitting is inhibited. In this case, adjust the receive
frequency so that the transmit frequency is within the band limits.

(NOTE: WHEN NEITHER "+" OR "-" APPEAR ON DISPLAY, UNIT IS IN
SIMPLEX OPERATION)

Note: While using an odd-split memory channel or transmitting,
you cannot change the offset direction.

* Selecting Offset Frequency
To access a repeater which requires an odd-split frequency pair,
change the offset frequency from the default which is used by
most repeaters. The default offset frequency on the 2 m band is
600 kHz (all models); the default on the 70 cm band is 5.0 MHz
(TH-F6A) or 1.6 MHz (TH-F7E); the default on the 1.25 m band is
1.6 MHz (TH-F6A).

1 Press [BAND] to select an amateur radio band you want to change
the offset frequency.

2 Press [MNU].

3 Turn the Tuning control or press [U]/[D] to select Menu No. 6 (OFFSET).

REVERSE FUNCTION
The reverse function exchanges a separate receive and transmit
frequency. So, while using a repeater, you can manually check the
strength of a signal that you receive directly from the other
station. If the station's signal is strong, both stations should
move to a simplex frequency and free up the repeater.

DIAGRAM HERE OF REPEATER AND REVERSE OPERATIONS

HANDHELD RX: 145.325 MHz TX: 144.725 MHz
REPEATER RX: 144.725 MHz TX: 144.725 MHz

Note: You can turn the Reverse function ON when you are operating
in Simplex mode. However, it does not change the TX/RX frequency.

AUTOMATIC SIMPLEX CHECK (ASC)
While using a repeater, the ASC function periodically checks the
strength of a signal that you are receiving directly from the
other station. If the station's signal is strong enough to allow
direct contact without a repeater, "R" indicator on the (VISUAL)
display starts blinking.

Press [REV] (1 s) to switch the function ON.  "R" appears when the

* Pressing the PTT switch causes "R" 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.

TONE FREQ. ID SCAN

This function scans through all tone frequencies to identify the
incoming tone frequency on a received signal. You may use the
function to find which tone frequency is required by accessing
your local repeater.

1 While the Tone function is ON, press [F], [TONE] (1 s) to start
the Tone Freq. ID scan.
 When the transceiver receives the signal, the scan starts.
 To reverse the scan direction, turn the Tuning control or
press [U]/[D].
 To quit the function, press [PTT] or [<].
 When the tone frequency is identified, a beep sounds and the
identified frequency appears. (VISUALLY)

2 Press [>] to program the identified frequency in place of the
current tone frequency.

 Press [<] if you do not want to program the identified
frequency.

 Press [U]/[D] while the identified frequency is blinking, to
resume scanning.

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.

14
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

Note: Not only can you store data in memory channels, but you can
also overwrite existing data with new data. The data listed below
can be stored in each memory channel:


Parameter \ Simplex & Repeater \ Odd-split
Receive frequency \ Yes \ Yes
Transmit frequency \ Yes \ Yes
Tone frequency \ Yes \ Yes
CTCSS frequency \ Yes \ Yes
CTCSS ON \ Yes \ Yes
DCS code \ Yes \ Yes
DCS ON \ Yes \ Yes
Offset direction \ Yes \ Yes
Offset frequency \ Yes \ Yes
Reverse On \ Yes \ N/A
Frequency step size \ Yes \ Yes
Memory channel lockout \ Yes \ Yes
Memory channel name \ Yes \ Yes
FINE tuning ON \ Yes \ Yes
Mode selection \ Yes \ Yes

Yes: Can be stored in memory.
N/A: Cannot be stored in memory.

Note: The transmit frequency must be on the same band as the
receive frequency band (Odd-split channel).

STORING SIMPLEX FREQUENCIES OR STANDARD REPEATER FREQUENCIES

1 Press [VFO].

2 Turn the Tuning control or press [U]/[D] to select your desired

 You can also directly enter desired frequency using the keypad
{page 7}.

3 If storing a standard repeater frequency, select the following
data:
 Offset direction {page 12}  Tone function, if necessary {page
13}  CTCSS/DCS function, if necessary {pages 28, 29} If storing
a simplex frequency, you may select other related data (CTCSS or
DCS settings, etc.).

4 Press [F].
 A memory channel number appears and blinks.  "I>"(TRIANGLE WITH
CLEAR CENTER)" indicates the current channel is empty; "I>"(TRIANGLE
WITH DARK CENTER) appears if the channel contains data.  Memory
channel number L0/U0 ~ L9/U9 {page 23}, I-0 ~ I-9 {page 20}, and
Pr1 and Pr2 {page 25} are reserved for other functions.

5 Turn the Tuning control or press [U]/[D] to select the memory
channel in which you want to store the data.

6 Press [MR] ([>] or [MNU]) to store the data to the channel.

STORING ODD-SPLIT REPEATER FREQUENCIES
Some repeaters use a receive and transmit frequency pair with a
non-standard offset. If you store two separate frequencies in a
memory channel, you can operate on those repeaters without
programming the offset frequency and direction.

1 Store the desired receive frequency and related data by the
procedure given for simplex or standard repeater frequencies
{above}.

or "Pr2" blinks and the B-band frequency changes to the priority channel.
 If you do not operate any control or key for 3 seconds after the signal
drops, the transceiver returns to the original frequency and resumes
Priority Scan.

2 To quit Priority Scan, press [F], [BAL] again.

25
7 SCAN
Note:
* The signal being received on the B-band may become intermittent
because the Priority Scan uses the B-band receiver to check the
priority channel(s) activities.
* When a signal is received on a Priority channel with a CTCSS or
DCS code programmed, the Priority channel is recalled even if a
different selective tone/code is detected. However, the
transceiver only unmutes if the signal has the same CTCSS tone or
DCS code.
* If the Tone Alert function {page 40} is ON for the B-band, it
overrides the Priority Scan function. This means that you cannot
monitor the received signal on the Priority Channels nor transmit
on the Priority Channels.
* Press and hold [MONI] to pause the Priority Scan when the
transceiver is not displaying a priority channel. Release [MONI]
to resume the Priority Scan.
* If you clear the Priority Channels {page 16}, the Priority Scan
stops.
* If you press any key other than the following keys while "Pr1"
or "Pr2" is blinking, the transceiver exits the Priority Scan:
[LAMP], [MONI], [A/B], [SQL], [BAL], [F] (1 s), and [PTT].
* If you perform the Visual Scan {below} while Priority Scan is
activated, the Priority Scan temporarily pauses.

INFORMATION CHANNEL SCAN
Information Channel Scan is similar to Group Scan. However, it
scans only Information channels.

1 Press [INFO].
 The last Information channel you used is recalled.

2 Press [INFO] (1 s) to start the Information Channel Scan.

3 To stop the Information Channel Scan, press [INFO].
 If necessary, press [A/B] to select the B-band and then press
[VFO] or [MR] to select another frequency (channel) for the
B-band.
Note: The transceiver stops scanning in all modes when it detects
a signal.

VISUAL SCAN
While you are receiving, Visual Scan allows you to monitor
frequencies near the current operating frequency. Visual Scan
graphically displays the busy status of all frequencies in the
selected range on the other band display area. You will see 6
different bargraph levels, for each frequency (channel) point
that represent relative S-meter levels.

The Visual Scan monitors 15 channels (frequencies) by centering
on the current channel (frequency). In this way, a total of 11
channels' (frequencies') signal strength status are graphically
displayed.
Note:
* When you perform the Visual Scan on the A-band, the transceiver
can output the audio. However, when you perform the Visual Scan
on the B-band, it cannot output the audio. The S-meter does not
reflect the signal strength, neither.
* When the VOX function is activated, you cannot perform the
Visual Scan.
* When the Visual Scan is in progress, the other scan functions.

USING VISUAL SCAN (VFO)

1 Select your desired band for Visual Scan.

2 Press [VFO].

3 Turn the Tuning control or press [U]/[D] to select your desired
center frequency.
 The transceiver scans the 5 upper frequencies and 5 lower frequencies
using the current VFO frequency step {page 37}.

4 Press [F], [INFO] to start Visual Scan (VFO).
 The scanning frequency is displayed on the current operating band and
the relative S-meter level of each frequency appears on the other band
display.
 To pause Scan, press and hold [MONI]. While the Visual Scan is
paused, the center frequency bar-graph blinks and you can monitor
the frequency. Release [MONI] to resume the Visual Scan.

5 To change the current scanning frequency, Turn the Tuning
control or press [U]/[D].
 The displayed frequency changes and the cursor moves.

6 To stop the Visual Scan, press [F], [INFO].
Note:
* You can press [PTT] (or [CALL] if 1750 Hz is programmed) to
transmit during the scan if the center frequency is within the
transmission frequency range. The center bar-graph blinks while
transmitting.
* If the Fine Tuning function is ON, the Visual Scan cancels the
Fine Tuning function and automatically adjusts the frequency to
the next available frequency.

(Pr1 and Pr2) cannot be locked out.
* Even if a memory channel is locked out, you can perform the
Call Scan {page 25} between the Call channel and memory channel.
* If the same memory channel is recalled to the A and B-band, you
cannot lock out the channel.

SCAN RESUME METHOD
The transceiver stops scanning at the frequency (or memory
channel) where a signal is detected. It then continues or stops
scanning according to which resume mode you have selected.

 Time-Operated mode (default)
The transceiver remains on a busy frequency (or memory channel)
for approximately 5 seconds, then continues to scan, even if the
signal is still present.

 Carrier-Operated mode
The transceiver remains on the busy frequency (or memory channel)
until the signal drops out. There is a 2-second delay between

27
SELECTIVE CALL
CTCSS and DCS
You may sometimes want to hear calls from only specific persons
or groups. In this case, use the selective call function. This
transceiver is equipped with CTCSS (Continuous Tone Coded Squelch
System) and DCS (Digital Coded Squelch). These selective calls
allow you to ignore (not hear) unwanted calls from other persons
who are using the same frequency. The transceiver unmutes only
when it receives the signal having the same CTCSS tone or DCS
code.

Note:
* CTCSS and DCS do not cause your conversation to be private or
scrambled. It only relieves you from listening to unwanted
conversations.
* CTCSS and DCS function in only FM mode.

CTCSS
A CTCSS tone is a sub-audible tone and is selectable from among
the 42 tone frequencies listed in the table on the following
page. The list includes 37 EIA standard tones and 5 non-standard
tones. You can select one of the tones to use as a CTCSS tone.

USING CTCSS

Press [TONE] until "CT" appears.
 Each time you press [TONE], the icon cycles as follows:
"T" (TONE)(VISUALLY BLACK BOX WITH WHITE T IN CENTER)-> "CT" (CTCSS)
-> "DCS" (DCS) -> "(BLANK DISPLAY VISUALLY)" (OFF)-> "T"(TONE).

When the CTCSS function is ON, you will hear calls only when the
selected CTCSS tone is received. To answer the call, press and
hold the PTT switch, then speak into the microphone.

Note:
* You cannot use the CTCSS and Tone/DCS functions simultaneously.
Switching the CTCSS function ON after having activated the
Tone/DCS functions deactivates the Tone/DCS functions.
* If you select a high CTCSS frequency, receiving audio or noise
that contains the same frequency portions may cause CTCSS to
function incorrectly. To prevent noise from causing this problem,
select an appropriate squelch level {page 6}.
* While transmitting the 1750 Hz tone by pressing [CALL] {page
13} , the transceiver does not transmit the CTCSS tone.

SELECTING A CTCSS FREQUENCY

1 While in CTCSS mode {above}, press [F], [TONE].

Note:
* signals are monitored through the speaker while scanning is in progress.
* CTCSS Freq. ID Scan does not scan the tone if a signal is not detected.
* If the CTCSS function is activated for both the A and B-band, the scan
speed may be slower.

DCS
DCS is similar to CTCSS. However, instead of using an analog audio tone,
it uses a continuous subaudible digital waveform that represents a 3-digit
octal number. You can select a DCS code from among the 104 DCS codes
listed in the table below.

USING DCS

Press [TONE] until "DCS" appears.
 Each time you press [TONE], the icon cycles as follows: "T" (TONE)
(VISUALLY BLACK BOX WITH WHITE T IN CENTER)-> "CT" (CTCSS) -> "DCS"
(DCS) -> "(BLANK DISPLAY VISUALLY)" (OFF)-> "T"(TONE).

When the DCS function is ON, you will hear calls only when the
selected DCS code is received. To answer the call, press and hold
the PTT switch, then speak into the microphone.
Note: You cannot use the DCS function and CTCSS/Tone functions
simultaneously. Switching the DCS function ON after having

DTMF FUNCTIONS
The keys on the keypad also function as DTMF keys; the 12 keys
found on a touch-tone phone plus 4 additional keys (A, B, C, D).
This transceiver also provides 10 dedicated DTMF memory channels.
You can store a DTMF number (16 digits max.) with a memory name
(8 digits max.) in each of the channels to recall later for speed
dialing.

Many repeaters in the U. S. A. and Canada offer a service called
Autopatch. You can access the public telephone network via such a
repeater by sending DTMF tones. For further information, consult
your local repeater reference.

MANUAL DIALING
Manual Dialing requires only two steps to send DTMF tones.

1 Press and hold the PTT switch to transmit.

UTILIZING THE B-BAND ABOUT THE B-BAND
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/1.25 m (TH-F6A only)/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 ">" 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 [U]/[D] to select your desired band in VFO
mode {page 7}.

3 Turn the Tuning control or press [U]/[D] 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 operating
in FM mode to transmit.

Operation {page 40}.

VOX (VOICE-OPERATED TRANSMIT)
VOX eliminates the necessity of manually switching to the
transmit mode each time you want to transmit. The transceiver
automatically switches to transmit mode when the VOX circuitry
senses that you have begun speaking into the microphone.
When you operate the VOX function, you must use an optional
accessory, HMC-3 or KHS-21. Because both the internal speaker and
microphone are too near to be used for the VOX function.

To turn the VOX function ON: Press [F], [SQL].
 "VOX" appears. (VISUAL DISPLAY)
 To exit VOX mode, press [F], [SQL] again.

return to 1200 bps {page 45}.
* While the VOX function is ON, you cannot use [U]/[D]/[<]/[>] to
adjust other settings, such as the frequency and operating band.
* While in the Menu mode {page 9}, the VOX function is disabled
temporarily.
* Since the VOX circuit must detect the presence of your voice,
you may notice a slight delay in transmission. The very first
part of your message may not be transmitted.
* Turn the HMC-3's VOX function OFF when you use the internal VOX
function.

VOX GAIN
To enjoy the VOX function, take the time to properly adjust the

and mode are as follows.
 A-band: 144.000 MHz/FM
 B-band: 440.000 MHz/FM (TH-F6A)
B-band: 430.000 MHz/FM (TH-F7E)
T
he 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.

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

15 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.

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 separating the CW
signal from other signals in the crowded band.

To best tune in to a SSB signal, follow the instruction below.

When you receive signals in USB mode:

1 Turn the Fine Tuning function ON {page 35}.

2 Tune to the target signal while starting at a lower frequency,
using the Tuning control.

When you receive signals in LSB mode:

1 Turn the Fine Tuning function ON {page 35}.

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 36} to reduce the interference
signal level. You may further have to adjust the volume level
while receiving the target signal.

BEAT AND NOISE
When you have the same 2 m, 1.25 m (TH-F6A only), and 70 cm band
frequencies for both A and B-band receivers, the Visual Scan may
indicate the signals on the bar-graph 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

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.
