Introduction
In an effort to better understand the operation of the Yupiteru MVT-7100, and to offer a valuable resource to other people who may be using these wonderful radios, I wrote this owner's guide.
It does not hurt that the originally supplied manual that comes with the radio is rather poor. Like many translations from the original Japanese, the grammar leaves much to be desired. And, on the whole, the organization of the topics is not helpful in gaining a useful understanding of the radio and how all the pieces interrelate.
This guide goes through the operation of the MVT-7100 in a step by step process starting with the basics and builds up to the operation of the more advanced features.
While I've never had the pleasure of playing with the MVT-7200, most of what appears here should apply to it. Where there are difference that I know of between these two radios, I have pointed them out as best I could.
Feel free to make copies of this document and distribute as you see beneficial to the radio monitoring hobby as long as it is done FREE of charge. 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!

Warning Contents
If the radio is being used with standard alkaline batteries, do not use the AC or car power adapters. External power should only be applied to the radio when it has been equipped with rechargeable batteries or the batteries have been removed from the radio.
Even if you do use power in this manner with rechargeable batteries, leaving the radio plugged in continually will overcharge and overheat the batteries. Both of which will drastically shorten their lifespan.

Definitions & Terms Contents
Here are some basic definitions as well as terms used in the MVT-7100 Instruction Manuals 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-7100 allows you to set the attenuator for individual memory channels as well as while performing a search.
Memory bank
An association of memory channels. This radio has 10 memory banks (1-0). 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 receive mode. The MVT-7100 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
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-7100 has 1 priority channel which is located at the end of "normal" memory.
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; only found on the MVT-7200)
  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 bands)
  LSB - Lower Sideband (mainly used below 25MHz & amateur radio bands)
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-7100 has 10 search bands.
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-7100 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-7100 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 index feature enabled, scanning or searching will pause on an active transmission for at most 5 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 or using a VFO. Available step sizes are :
  Hz : 50/100
  kHz : 1/5/6.25/9/10/12.5/20/25/50/100/125
  NOTE: Only the MVT-7200 has the 125 kHz step size.
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, and delay.
Available Modes Contents
Memory
The radio is in Memory mode when a memory channel number is visible in the upper left corner and followed by 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 two modes are :
  Continuous : scanning of all non-empty banks
  Bank : scanning of up to four banks
The three 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 six scan mode types :
  Continuous Normal
  Continuous Program
  Continuous Mode
  Bank Normal
  Bank Mode
  Bank Program
Search Band Programming
In this mode, the search bands (1-0) 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 which can be performed.
The two modes are :
  VFO : starts searching from the current VFO frequency
  Band : search a preprogrammed search band
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
The radio is in VFO mode when there is a frequency displayed but no memory channel or 'CH' LCD indicator present. Pressing the MR key toggles between VFO and Memory modes.
Terminology Contents
   When you see 'FUNC + key' press FUNC. You will hear a beep (if enabled) and FUNC will be displayed.
   Press 'key'.

NOTE : When a VFO is copied to memory, the following settings are also copied to that memory channel.
1. Frequency
2. Step size
3. Receive mode
Each time a memory write (copying VFO to memory) is performed, the current memory channel is incremented by one. To write successive memory channels, simply enter the frequency data and use the method to copy this frequency to the current memory channel.
When frequency data is copied from a VFO to a priority channel, a memory channel number of 1000 must be specified.
To copy to the priority channel
1. Enter 1000
2. Press FUNC + MW
3. A double-beep is heard.
Searching
Searching for new frequencies can be performed using the VFO frequency as the starting point. Refer to Searching Modes for further details.

This mode allows for the scanning of every non-empty bank.
  Bank
This mode allows for up to four specified banks to be scanned. Up to four banks from memory banks 1-0 can be specified.
The three minor modes are:
  Normal
This mode simply scans all non-empty memory channels.
  Mode
This mode scans memory channels with the specified receive mode (AM/FM/LSB/NAM/USB/WFM; NAM for MVT-7200 only).
  Program
This mode scans memory channels which have been specially tagged.
Scan Pass
Regardless of the chosen scanning mode, channels that have been marked as 'pass' will not be scanned. On most radios, this feature is referred to as channel lockout.

Other Features Contents
AM Antenna  
To aid in the reception of medium wave (540-1710kHz) broadcasts, the MVT-7200 is equipped with an internal ferrite bar antenna that is used in lieu of the stock antenna for this band.
The MVT-7100 must use the antenna attached to the BNC connector for medium wave band received.
Attenuator Contents
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 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.
The VFO has its own attenuator settings well as each memory channel. After a search band search operation is started, the Attenuator can be enabled or disabled as is deemed necessary.
Battery Saver Contents
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.
Three of the numeric keys are used to specify the battery saver level:
1 = sleep for 0.3 seconds out of every 0.6 seconds.
2 = sleep for 0.9 seconds out of every 1.2 seconds.
3 = sleep for 1.5 seconds out of every 1.8 seconds.
To enable the Battery Saver
1. Press 1, 2 or 3
2. Press FUNC + SAVE
3. SAVE appears on the LCD with 1, 2 or 3.
NOTE: If step #1 is skipped, a value of 1 is assumed.
To disable the Battery Saver
1. Press FUNC + SAVE
2. SAVE disappears.
The Battery Saver is only effective when used in VFO or Memory modes. If no transmission is detected on the 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.
NOTE : Starting a search or scan turns off the battery saver.
Beep Contents
The MVT-7100 sounds a beep tone each time a key is pressed. This helps to provide audible feedback during radio operations. Shipped from the factory, the beep tone is enabled which can be verified by the presence of the BEEP indicator. For more discreet operations, it may be necessary to disable this feature.
To disable the beep tone
1. Press FUNC2 + BEEP
2. The BEEP indicator disappears.
To enable the beep tone
1. Press FUNC2 + BEEP
2. The BEEP indicator appears.
Delay Contents
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
2. The DLY indicator disappears.
Lamp Contents
The MVT-7100 contains a brilliant backlighting system which is used to illuminate both the display and keypad for nighttime operations. The LAMP button must be pressed and held to activate the backlight. When the buttons is released, the backlight turns off.

The MVT-7200 comes with a switch which can be used to keep the backlight on if so desired.
NOTE :
Excessive use of the Lamp feature will dramatically reduce the operational time of the radio when batteries are being used.
Monitor Contents
The MONI button on the side of the radio is used it immediately open the squelch to help aid in the reception of signals whose strength might be below the squelch threshold or for monitoring weak signals which are fading in and out resulting in repetitive squelch operations.
Reset Contents
The MVT-7100 has a reset feature which allows the processor to be reset should the radio act peculiar. Using this feature effectively restores the radio to the condition it was in when it left the factory.
ALL MEMORY DATA WILL BE ERASED! ALL SEARCH BANDS AND VFO SETTINGS WILL BE RESET TO THEIR DEFAULT VALUES!
To perform the reset
1. Make sure the radio is powered on
2. Use a small object to press and hold the micro switch located beneath the small opening on the side panel
3. The radio will reset and then go to VFO mode.
Skip Contents
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 occurring 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 five 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.
NOTE : The Skip function has no effect on active priority channel signals.
