Introduction
==============================================================================
In an effort to supply MVT-7300 owners with a better manual
for their new
radios, this guide was written and based largely on the
original MVT-9000
Owner's Guide written by Rich Wells, N2MCA. It was modified
from its
original form by Mika, OH5HST, of Bandercom, Inc. and
subsequently edited
by Rich Wells.
This guide goes through the operation of the MVT-7300 in
a step by step
process starting with the basics and builds up to the
operation of the
more advanced features.
Feel free to make copies of this document and distribute
as you see
beneficial to the radio monitoring hobby. I simply ask
that this information
be kept intact. A lot of hard work and effort has gone
into the writing of
this guide. I would appreciate it if every effort is made
to keep this
document whole with me as the original author.
If you would like to share your thoughts about this owner's
guide, have
suggestions for its improvement or have further questions,
feel free to
send me e-mail.
Happy reading and strong signals!

Definitions & Terms
==============================================================================
Here are some basic definitions as well as terms used
in the MVT-7300
Instruction Manual that will help you to use this guide
more effectively.
Attenuator
----------
A device which is used to diminish the strength of an
incoming signal. This
is typically used to alleviate overloading of the front
end radio circuitry
by very strong, and usually nearby, transmissions. The
MVT-7300 allows you
to set the attenuator for individual memory channels as
well as while
performing a search.
Auto Mode/Step
--------------
This radio comes already programmed with regard to the
recieve mode, step
size and duplex shift width that will be used dependent
on the active
frequency. When you key in a frequency, the radio will
automatically select
a receive mode and step size based on the range your frequency
falls in. You
will likley find a number of ranges where this data is
not correct due to
differences in national frequency bandplans.
Duplex Shift
------------
A lot of radio systems use one frequency for transmitting
and another for
receiving (usually the inputs and outputs to a repeater
site). The
difference between these two frequencies is referred to
as the duplex shift
width. The MVT-7300 uses a fixed shift width so that these
two frequencies
can be monitored easily with a simple keypress.
NOTICE: The current MVT-7300 uses a Japanese
bandplan so the shift
width between the frequencies may not be correct for your
country.
Memory Bank
-----------
An association of memory channels. This radio has 10 memory
banks (0 - 9).
Since it also has 1000 memory channels, this means there
are 100
memory channels per memory bank.
Memory Channel
--------------
A location used to store a frequency and its associated
settings such
as receive mode, attenuator, duplex width and alpha-tag.
The MVT-7300
has 1000 memory channels which are divided into 10 banks.
Pass
----
Refers to scanning and searching operations. A memory
channel can be
passed so that it is not checked during a scan operation.
A frequency
can be passed so it is not checked during a search operation.
See Scan
Pass and Search Pass for more information.
Priority Channel
----------------
A special memory channel that can be checked on a periodic
basis for active
transmissions. This is usually programmed with very important
frequency
that you do not want to miss activity on. The MVT-7300
has 1 priority
channel which is referred to as memory channel 1000.
Receive Mode
------------
The method by which radio transmissions will be demodulated
so that the
resultant audio portion may be directed to the speaker.
Available receive
modes are:
AM - Amplitude Modulation (below
30MHz, amateur radio, commercial
and military aircraft)
NAM - Narrow AM (mainly used below 25MHz)
FM - Frequency Modulation (most
VHF/UHF communications)
WFM - Wide FM (for FM radio and TV audio)
USB - Upper Sideband (mainly used below
25MHz & amateur radio)
LSB - Lower Sideband (mainly used below
25MHz & amateur radio)
CW - Continuous Wave (amateur
radio Morse code)
Scan Pass
---------
Most receivers refer to this feature as channel lockout.
Once a frequency
has been programmed into memory, a scanning operation
will stop on this
channel if an active transmission is detected. Certain
frequencies may
contain transmissions which are very or always active.
To keep the
scanning operation from stopping on these channels, they
can be locked-
out/skipped/passed during a scan.
Scanning
--------
The act whereby memory channels are successively checked
for active
radio transmissions of their programmed frequencies.
Search Band
-----------
A feature which allows a pre-defined frequency range to
be programmed so
that it can be repeatedly searched for active transmissions.
Stored with
each search band are a starting frequency, ending frequency,
receive mode
and step size. The MVT-7300 has 12 search bands. 10 of
them are
user-programmable while the other 2 contain preprogrammed
frequencies which
can not be altered.
Search Pass
-----------
Some receivers refer to this feature as search-skip. If
you have a known
frequency which you would like to skip while performing
a search, it can
be placed in a special memory. Yupiteru refers to this
as the Search
Pass Memory. Once placed in this memory, this frequency
will not be tested
for an active transmission, or in other words it's skipped/passed
when
performing a search. The MVT-7300 has 500 search pass
frequencies.
Searching
---------
The act whereby a frequency is incremented or decremented
successively
to detect active radio transmissions in a given frequency
range. Searching
is usually performed on a programmed Search Band.
Skip
----
The MVT-7300 has a feature called Skip which allows a
paused scan or search
to resume after a fixed time. Normally, during a scan
or search, if an
active transmission is detected, the scanning or searching
operation will be
paused until the transmission ceases. Once the transmission
goes away, the
scanning or searching operation resumes. If you have the
skip feature
enabled, scanning or searching will pause on an active
transmission for at
most 4 seconds before resuming.
Step Size
---------
A value in Hertz (Hz) or kiloHertz (kHz) that indicates
the amount by which
a frequency will be changed due to user or radio control
while searching
for active transmissions. Available step sizes are :
Notice! Step size depend mode.
AM/NAM/FM: Auto step
1, 5, 6.25, 8, 9, 10, 12.5, 15, 20, 25, 30, 50, 100 kHz
WFM: Auto
step
25, 50, 100, 125 kHz
USB/LSB/CW: Auto step
50, 100 Hz
1, 5, 6.25, 8, 9, 10, 12.5, 15, 20, 25, 30, 50, 100 kHz
S-meter
-------
A feature used to graphically represent the strength of
the signal being
received. It is usually calibrated to a dB (logarithmic)
scale. A bar
graph is used where more bars indicate a stronger signal.
VFO
---
A temporary location to store a frequency so that a memory
channel does
not have to be programmed. Associated with this frequency
are various
settings such as receive mode, step size, attenuator,
etc. The MVT-7300
has a single VFO.
==============================================================================
Available Modes
==============================================================================
Memory
------
The radio is in Memory mode when a memory channel number
is visible in the
upper left corner next to the CH indicator. Pressing the
MR key toggles
between Memory and VFO modes.
Priority
--------
Priority mode is enabled when the PRI indicator is visible.
This is a mode
independent of the VFO, Memory, Scanning or Searching
modes.
Scanning
--------
In this mode, the scanning operation checks the specified
banks for active
transmissions on the programmed frequencies within those
banks. There are
two scanning modes with three scanning sub-modes for a
total of six
different types of scan that can be performed.
The 2 modes are:
Continuous : scanning of all non-empty
banks
Bank
: quick and dirty scanning of up to 4 banks
The 3 sub-modes are:
Normal : a normal scan
Mode : scans only
those channels with the specified receive mode
Program : scans only those channels
which have been program tagged
This gives us the following 6 scan mode types:
Continuous Normal
Continuous Mode
Continuous Program
Bank Normal
Bank Mode
Bank Program
Search Band Programming
-----------------------
In this mode, the search bands (1-10) used to perform
searches are
programmed with starting and ending frequencies as well
as step sizes
and receive modes.
Searching
---------
In this mode, the searching operation checks for active
transmissions on
the frequencies in the specified search range. There are
two searching modes
and two searching sub-modes for a total of four different
types of search to
be performed.
The 2 modes are:
VFO : starts searching from the
current VFO frequency
Band : search one of the programmed
search bands
The 2 sub-modes are:
Normal : a normal
search
Auto-Store : stores active transmissions
in Bank 10
This gives us the following 4 search mode types:
VFO Normal
VFO Auto-Store
Band Normal
Band Auto-Store
There is also a preprogrammed band search mode designed
to search one of
the two factory preprogrammed search bands.
Search Pass
-----------
The radio is in Search Pass mode when a blinking P indicator
is visible
and the contents of the Search Pass memory are being displayed.
VFO

you want store the search 1-0 (11 & 12 are fixed
banks)
7. The radio beeps
twice and returns to VFO mode
---------------------------------------------------------------------------
Searching Modes
---------------------------------------------------------------------------
The MVT-7300 offers four different ways
to search for active frequencies.
There are two major and two minor modes
of operation. By combining a
major mode with a minor mode, four different
search types are available.
The two major modes are:
VFO
---
This mode allows for a search to be started from one of the
currently displayed VFO frequencies.
Band
----
This mode allows for up to four specified bands to be searched.
The two minor modes are:
Normal
------
This mode performs a simply search which pauses when frequency
activity is detected so that you may listen.
Auto-Store
----------
This mode stores active frequencies into a predefined bank.
Changing Search Direction
-------------------------
All search modes start
at the designated starting frequency and
successively increment
this frequency using the current step size
to try and find frequency
activity. To reverse the direction of the
search at any time,
simply turn the rotary control in a
counter-clockwise
direction or press the down/left arrow key. At
any time, the search
direction can be reversed by simply using the
rotary control or
arrow keys.
Resume Searching
----------------
If the search stops
on an active frequency that you do not wish to
monitor, simply use
the rotary control or arrow keys to resume
the search.
Cancelling Search
-----------------
To cancel a search
while it is running, simply press SRCH or MR.
Auto-Store
----------
This mode performs
a search and if activity is detected on a
frequency, that frequency
is stored in bank j and the search
continues. You do
not get to hear the audio from this frequency
activity because the
radio pauses just long enough to store the
frequency and then
resumes searching.
Each time an Auto-Store
search is started, the last 50 channels of
bank 0 (950 - 999)
are erased. As active frequencies are found, there
will be a short pause
as the radio stores the frequency in bank 0.
Once the frequency
is stored, there will be a beep and the radio will
then continue the
search.
During the search,
should channels 950 - 999 become full, the search
will be aborted.
The Four Searching Modes
-----------------------
VFO Normal
----------
This mode is used to start a simple search from the VFO. Before
starting the search, be sure the frequency, step size and receive
mode are set appropriately. To start this mode
1. Press SRCH
2. The SRCH indicator appears
VFO Auto-Store
--------------
This mode is used to start a simple search from the current VFO
frequency and store active frequencies into bank j. Before starting
the search, be sure the frequency, step size and receive mode are
set appropriately. To start this mode
1. Press FUNC + AW SET
2. The SRCH indicator blinks informing Auto-Store is active
3. Press SRCH
Band Normal
-----------
This mode is used to search up to 4 specified bands. To start this
mode
1. Specify up to four bands from 0-9 by pressing the appropriate
digit keys.
2. Press SRCH
3. The B-SRCH indicator appears along with programmed search
band settings.
Band Auto-Store
---------------
This mode is used to search one specified band and store active
frequencies into memory channels 950 - 999. To start this mode
1. Press FUNC + AW SET
2. The SRCH indicator blinks informing Auto-Store is active
3. Specify the search band from 0-9 by pressing the appropriate
digit key
4. Press SRCH
5. The B-SRCH indicator blinks and programmed search band
settings are displayed.
Preprogrammed Band Search
-------------------------
The MVT-7300 comes
with bands 11 and 12 which are preprogrammed at
the factory and can
not be changed. Band 11 is programmed with a large
number of business
frequencies (which will most likely only be usable
in Japan) while band
12 is programmed with the 62 TV audio
frequencies.
To start this mode
1. Press 11 or 12 to specify the band to be searched
2. Press SRCH
3. 'bus' will appear on the display if band 11 is searched while
the appropriate TV channel numbers will be displayed if band
12 is searched
4. Press SRCH to cancel the band search
Attenuator
----------
The attenuator may
be used during a search to reduce signal strength.
See Attenuator in the
Other Features section for further details.
Delay
-----
The delay may be used
during a search to lengthen the search resume
delay time from 2
to 4 seconds. This feature will have no function
if Auto-Store is enabled.
See Delay in the Other
Features section for further details.
Skip
----
The skip feature may
be used during a search to make sure the search
does not stay on any
active frequency more than 4 seconds. This
feature will have
no function if Auto-Store is enabled.
See Skip in the Other
Features section for further details.
Search Pass
-----------
Regardless of the
chosen search mode, frequencies that have been
marked as 'pass' will
not be tested for activity. To read more about
this capability, see
the Search Pass Mode section.
---------------------------------------------------------------------------
Search Pass Mode
---------------------------------------------------------------------------
This mode allows you to display and
edit the contents of the Search
Pass memory. This memory contains a
list of frequencies which are to be
ignored when the radio is in one of
the search modes. By doing so, this
allows you to skip over frequencies
of known origin or those that are
active most/all of the time. Up to 500
frequencies can be entered into
this memory.

==============================================================================
Other Features
==============================================================================
---------------------------------------------------------------------------
Attenuator
---------------------------------------------------------------------------
If the radio is used in an area where
excessively strong signals are
active, it may be necessary to reduce
their strength to ensure that
the radio receiver functions properly.
The Attenuator is used to
reduce the strength of all signals entering
into the receiver.
Signals which enter the radio and are
too powerful for it to handle,
may result in various forms of interference.
Such signals may effect
frequencies to either side or can even
desensitize the receiver so
that it may not be able to receive signals
it normally can.
To enable the Attenuator
1. Press FUNC + ATT
2. The ATT indicator
appears
To disable the Attenuator
1. Press FUNC + ATT
2. The ATT indicator
disappears
Both VFOs have their own attenuator setting.
Each memory channel can
be individually programmed with an attenuator
setting. After a search
operation is started, the Attenuator
can be enabled or disabled as is
deemed necessary.
---------------------------------------------------------------------------
Battery Meter
---------------------------------------------------------------------------
The Battery Meter is used to give a
graphical indication of the power
remaining in the batteries. It is located
in the upper right corner of
the LCD and looks like a battery lying
on its side.
When new or freshly charged batteries
are put in the radio, both bars
inside the battery icon should be visible.
As the battery power depletes,
one bar, then the other will disappear.
The batteries will then need to
be replaced soon.
If the battery icon begins to flash,
that means the power level is
dangerously low and the radio is close
to turning itself off. Replace
the batteries immediately should this
occur.
---------------------------------------------------------------------------
Battery Saver
---------------------------------------------------------------------------
To extend the operating time of the
radio, the Battery Saver feature is
used. Not only can this feature be enabled
or disabled upon request,
the amount of time the saver circuitry
is active can be selected.

displayed frequency within five
seconds, the Battery Saver is engaged.
Once engaged, the Battery Saver puts
the radio "to sleep" for a period
of time, then "wakes up" briefly to
check for an active transmission.
The amount of time the radio spends
"sleeping" can be selected. While
the radio is "asleep", power usage is
lowered thus saving battery
power. The longer the sleep time, the
more power is saved and the
longer the batteries will last.
To select the sleep time

Cloning
---------------------------------------------------------------------------
Cloning is used to transfer all of the
data and settings from one
MVT-7300 into another. This makes it
easy for one owner to easily share
their radio setup with another. It can
also be used by dealers to set up
the radios they sell for customers upon
request.
In the procedure that follows, the MVT-7300
which will be sending its
data to the other MVT-7300 will be called
the Master. The MVT-7300 which
receives the programming data from the
master is called the Slave.
To Clone the contents of the Master to
the Slave
1. Connect the Master
to the Slave using a cable with 3.5mm plugs on
both ends and connected to the EAR jack of each unit
2. Turn on both the
Master and Slave
3. Set both Master
and Slave to VFO mode
4. On both radios

press 6 then ENT. This puts it into a state
waiting to receive the cloning data
7. On the Master unit,
press 1 then ENT. This starts the sending of
cloning data
8. Both LCDs will
update with memory addresses as data is transferred
WARNING:
While data is being transferred, DO NOT press any keys on
either unit, DO NOT try to turn the radios off and DO NOT
unplug the cable from either end!
Note:
This data transfer operation will take several minutes.
9. When the Master
unit is done sending, its display will return to
'Pc Int'
10. When the Slave unit
is done receiving, it will turn itself off
and the display will show 'CLEAr' for one second. If there is an
error in the transfer, the display will show 'Error' and then
return to 'Pc Int' (if this happens start the entire procedure
over)
11. Turn off the Master
unit
12. Disconnect the cable
from both EAR jacks
---------------------------------------------------------------------------
Delay
---------------------------------------------------------------------------
During a scan or search operation, after
a transmission ends, there will
be a two second delay before the scan/search
is resumed. This delay
allows for a response to be heard. To
increase this delay time to four
seconds, the Delay function is used.
To enable Delay
1. Press FUNC + DELAY
2. The DLY indicator
appears
To disable Delay
1. Press FUNC + DELAY

---------------------------------------------------------------------------
Monitor
---------------------------------------------------------------------------
The MONI button on the side of the radio
is used for several purposes.
Normally, pressing it immediately opens
the squelch. This allows for
checking transmissions whose strengths
might be below the squelch
threshhold or for monitoring weak signals
which are fading in and out
resulting in repetitive squelch operations.
When the duplex function is enabled in
VFO mode, MONI is used to receive
the duplex shift frequency.
---------------------------------------------------------------------------
Power-on Resume
---------------------------------------------------------------------------
This built-in functionality allows the
MVT-7300 to continue doing what
it was doing when it was powered off,
in some instances. Scanning
operations will not be resumed but will
leave the radio in Memory
Mode on the last accessed channel.
If the radio was searching when it was
turned on, upon power-on, it will
enter Search Pause mode. Simply press
SRCH to resume the search.
The settings regarding Bandscope and
Priority mode will be rememberd so
that they can be set appropriately upon
power-on.
---------------------------------------------------------------------------
Reset
---------------------------------------------------------------------------
If the MVT-7300 should behave oddly
or if you wish to clear the entire
contents of memory to start "fresh,"
the radio can be reset.
WARNING: Resetting the MVT-7300 will
erase all memory contents, return
all settings to their default values, and reprogram all the
search bands to their factory settings!
To reset the radio

---------------------------------------------------------------------------
Skip
---------------------------------------------------------------------------
The Skip function is used during scan
and search modes to prevent the
radio from stopping on any one frequency
for an undue amount of time.
Normally, when scanning or searching
comes across an active transmission
it will stop on that frequency until
the transmission ceases and then
resume scanning/searching. For some
situations, staying on one frequency
for too long may miss transmissions
occuring on other frequencies.
When the Skip function is enabled, if
the scan or search operation
stops on an active transmission, it
will resume the scan/search when
the transmission ends or four seconds
have elapsed; whichever occurs
first.
To enable Skip
1. Press FUNC + SKIP
2. The SKIP indicator
appears
To disable Skip
1. Press FUNC + SKIP
2. The SKIP indicator
disappears
