You may also build your own cable using a four-conductor miniature phone plug, per the diagram below. The audio level from the receiver to the TNC may be adjusted by using the VOLUME knob, as with voice operation.
OPERATION Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many features of the VX-7R. I know you’re anxious to get on the air, but I encourage you to read the “Operation” section of this manual as thoroughly as possible, so you’ll get the most out of this fantastic new transceiver. Now. . .let’s get operating! SWITCHING POWER ON AND OFF 1. Be sure the battery pack is installed, and that the battery is fully charged. Connect the antenna to the top panel ANTENNA jack.
OPERATION SQUELCH ADJUSTMENT The VX-7R’s Squelch system allows you to mute the background noise when no signal is being received. Not only does the Squelch system make “standby” operation more pleasant, it also significantly reduces battery current consumption. The Squelch system may be adjusted independently for the FM and Wide-FM (FM Broadcast) modes. 1. Press the key, then press the MONI switch on the left side of the radio.
OPERATION SELECTING THE OPERATING BAND In the factory default configuration, the VX-7R operates in the “Dual Receive” mode. During Dual Receive operation, the “Main” band frequency will be displayed on the upper side of the LCD, and the “Sub” band frequency will be displayed on the lower side, with the “Operating” band (the band on which transmission and band/frequency change are possible) being indicated in large characters, and “Receive only” band being indicated in small characters.
OPERATION SELECTING THE FREQUENCY BAND The VX-7R covers an incredibly wide frequency range, over which a number of different operating modes are used. Therefore, the VX-7R’s frequency coverage has been divided into different operating bands, each of which has its own pre-set channel steps and operating modes. You can change the channel steps and operating modes later, if you like (see page 25).
OPERATION FREQUENCY NAVIGATION The VX-7R will initially be operating in the “VFO” mode, as just described. This is a channelized system which allows free tuning throughout the currently-selected operating band. Three basic frequency navigation methods are available on the VX-7R: 1) Tuning Dial (Outer ring of dual control on Top Panel) Rotation of the DIAL allows tuning in the pre-programmed steps established for the current operating band.
OPERATION AUDIO MUTING The Audio Mute feature is useful in situations where it would be helpful to reduce the audio level of the “Receive Only” band (Small character display) whenever you receive a signal on the “Main” band (Large character display) during Dual Receive operation. To activate the Audio Mute feature: key, then press the key to enter the Set mode. 1. Press the 2. Rotate the DIAL to select the Menu Item labeled (Basic Operation #8: MUTE SET). 3.
OPERATION TRANSMISSION Once you have set up an appropriate frequency inside one of the three (or four) Amateur bands on which the VX-7R can transmit (50 MHz, 144 MHz, or 430 MHz, plus 222 MHz on the USA version), you’re ready to transmit. These are the most basic steps; more advanced aspects of transmitter operation will be discussed later. 1. To transmit, press the PTT switch, and speak into the front panel microphone (located in the upper right-hand corner of the speaker grille) in a normal voice level.
OPERATION TRANSMISSION key,, 2) When you are operating on one of the Low power settings, you can press the then press the PTT switch, to cause the VX-7R to transmit (temporarily) on High power. After one transmission, the power level will revert to the previously-selected Low power setting. VOX OPERATION The VOX system provides automatic transmit/receive switching based on voice input to the microphone.
OPERATION AM BROADCAST RECEPTION The VX-7R includes provision for reception of AM broadcasts, either on the standard medium-wave (MW) broadcast band, or on the shortwave bands up to 16 MHz. 1. Set the VX-7R to the VFO mode on the “Main” band. 2. Press the key (or press à ) repetitively until you see a frequency in the frequency range desired. The MW coverage is 0.5 MHz to 1.8 MHz, while the shortwave broadcast coverage is 1.8 MHz to 16 MHz.
OPERATION FM BROADCAST/TV AUDIO RECEPTION The VX-7R also includes provision for reception in the FM broadcast band, utilizing a wide-bandwidth filter which provides excellent fidelity. To Activate FM Broadcast Reception 1. Be sure that the VX-7R is set to the VFO mode on the “Main” band. 2. Press the key (or press à ) repetitively until a frequency in the FM broadcast band appears on the display. The total frequency range included in the “FM” band is 59-108 MHz. 3.
OPERATION WEATHER BROADCAST RECEPTION The VX-7R includes a unique feature which allows reception of weather broadcasts in the 160-MHz frequency range. Ten standard Weather Broadcast channels are pre-loaded into a special memory bank. To listen to a Weather Broadcast Channel or VHF Marine Channel: key, then press the key to recall the 1. Press the Weather Broadcast channels. 2. Turn the DIAL knob to select the desired Weather Broadcast channel. 3.
OPERATION KEYBOARD LOCKING In order to prevent accidental frequency change or inadvertent transmission, various aspects of the VX-7R’s keys and switches may be locked out.
OPERATION KEYPAD/LCD ILLUMINATION Your VX-7R includes a reddish illumination lamp which aids in nighttime operation. The red illumination yields clear viewing of the display in a dark environment, with minimal degradation of your night vision. Three options for activating the lamp are provided: KEY Mode: Illuminates the Keypad/LCD for 5 seconds when any key pressed. CONTINUE Mode: Illuminates the Keypad/LCD continuously. OFF Mode: Disables the Keypad/LCD lamp.
ADVANCED OPERATION Now that you’re mastered the basics of VX-7R operation, let’s learn more about some of the really neat features. SETTING THE FREQUENCY DISPLAY IMAGE SIZE VFO Mode When operating in the VFO mode during the “Mono” band operation, pressing the key, then pressing the or key, causes the LCD to “toggle” between display of doublesize characters and large characters. However, this feature does not work during Dual Receive operation, as two frequencies are displayed in that instance.
ADVANCED OPERATION CHANGING THE OPERATING MODE The VX-7R provides for automatic mode changing when the radio is tuned to different operating frequencies. However, should an unusual operating situation arise in which you need to change between the available operating modes (FM-Narrow, FM-Wide, and AM), here is the procedure for doing so: 1. Press the key, then press the key to enter the Set mode. 2. Rotate the DIAL to select the Menu Item labeled (Basic Setup #4: RX MODE). 3.
ADVANCED OPERATION REPEATER OPERATION Repeater stations, usually located on mountaintops or other high locations, provide a dramatic extension of the communication range for low-powered hand-held or mobile transceivers. The VX-7R includes a number of features which make repeater operation simple and enjoyable. Repeater Shifts Your VX-7R has been configured, at the factory, for the repeater shifts customary in your country.
ADVANCED OPERATION REPEATER OPERATION Manual Repeater Shift Activation If the ARS feature has been disabled, or if you need to set a repeater shift direction other than that established by the ARS, you may set the direction of the repeater shift manually. To do this: 1. Press the key, then press the key to enter the Set mode. 2. Rotate the DIAL to select the Menu Item labeled (Basic Setup #7: RPT SHIFT). 3. Press the or key to select the desired shift among “–RPT,” “+RPT,” and “SIMP.” 4.
ADVANCED OPERATION REPEATER OPERATION Checking the Repeater Uplink (Input) Frequency It often is helpful to be able to check the uplink (input) frequency of a repeater, to see if the calling station is within direct (“Simplex”) range. key. You’ll notice that the display has shifted to the repeater To do this, just press the uplink frequency. Press the key again to cause operation to revert to normal monitor-ing of the repeater downlink (output) frequency.
ADVANCED OPERATION CTCSS OPERATION Many repeater systems require that a very-low-frequency audio tone be superimposed on your FM carrier in order to activate the repeater. This helps prevent false activation of the repeater by radar or spurious signals from other transmitters. This tone system, called “CTCSS” (Continuous Tone Coded Squelch System), is included in your VX-7R, and is very easy to activate. CTCSS setup involves two actions: setting the Tone Frequency and then setting of the Tone Mode.
ADVANCED OPERATION DCS OPERATION Another form of tone access control is Digital Code Squelch, or DCS. It is a newer, more advanced tone system which generally provides more immunity from false paging than does CTCSS. The DCS Encoder/Decoder is built into your VX-7R, and operation is very similar to that just described for CTCSS. Your repeater system may be configured for DCS; if not, it is frequently quite useful in Simplex operation if your friend(s) use transceivers equipped with this advanced feature.
ADVANCED OPERATION TONE SEARCH SCANNING In operating situations where you don’t know the CTCSS or DCS tone being used by another station or stations, you can command the radio to listen to the incoming signal and scan in search of the tone being used. Two things must be remembered in this regard: ¦ You must be sure that your repeater uses the same tone type (CTCSS vs. DCS).
ADVANCED OPERATION CTCSS/DCS BELL OPERATION During CTCSS Decode or DCS operation, you may set up the VX-7R such that a ringing “bell” sound alerts you to the fact that a call is coming in. Here is the procedure for activating the CTCSS/DCS Bell: 1. Set the transceiver up for CTCSS Decode (“Tone Squelch”) or DCS operation, as described previously. 2. Adjust the operating frequency to the desired channel. 3. Press the key, then press the key to enter the Set mode. 4.
ADVANCED OPERATION TONE CALLING (1750 HZ) If the repeaters in your country require a 1750-Hz burst tone for access (typically in Europe), you can set the MONI key to serve as a “Tone Call” switch instead. To change the configuration of this switch, we again use the Menu to help us. 1. Press the key, then press the key to enter the Set mode. 2. Rotate the DIAL to select the Menu Item labeled (Misc Setup #3 MON/T-CAL). 3. Press the or key to select “T-CALL” on the display. 4.
ADVANCED OPERATION ARTS (AUTOMATIC RANGE TRANSPONDER SYSTEM) The ARTS feature uses DCS signaling to inform both parties when you and another ARTSequipped station are within communications range. This may be particularly useful during Search-and Rescue situations, where is important to stay in contact with other members of your group. Both stations must set up their DCS codes to the same code number, then activate their ARTS feature using the command appropriate for their radio.
ADVANCED OPERATION ARTS (AUTOMATIC RANGE TRANSPONDER SYSTEM) 4. Press the key, then press the functioning of the transceiver. key to exit ARTS operation and resume normal ARTS won’t work if you have used the Lock feature to disable the PTT! ARTS Polling Time Options The ARTS feature may be programmed to poll every 25 seconds (default value) or 15 seconds. The default value provides maximum battery conservation, because the polling signal is sent out less frequently. To change the polling interval: 1.
ADVANCED OPERATION ARTS (AUTOMATIC RANGE TRANSPONDER SYSTEM) CW Identifier Setup The ARTS feature includes a CW identifier, as discussed previously. Every ten minutes during ARTS operation, the radio can be instructed to send “DE (your callsign) K” if this feature is enabled. The callsign field may contain up to 16 characters. Here’s how to program the CW Identifier: 1. Press the key, then press the key to enter the Set mode. 2. Rotate the DIAL to select the Menu Item labeled (ARTS #3: CW ID). 3.
ADVANCED OPERATION DTMF OPERATION The VX-7R’s 16-button keypad allows easy DTMF dialing for Autopatch, repeater control, or Internet-link access purposes. Besides numerical digits [0] through [9], the keypad includes the [*] and [#] digits, plus the [A], [B], [C], and [D] tones often used for repeater control. Manual DTMF Tone Generation You can generate DTMF tones during transmission manually. 1. Press the PTT switch to begin transmission. 2. While transmitting, press the desired numbers on the keypad. 3.
ADVANCED OPERATION DTMF OPERATION To send the telephone number: 1. Press the key, then press the key to enter the Set mode. 2. Rotate the DIAL to select the Menu Item labeled (TSQ/DCS/DTMF #7: DTMF DIALER). 3. Press the or key to set the DTMF Autodialer function to the “ON” position. 4. Press the PTT switch to exit to normal operation and activate the DTMF Autodialer function (the “ ” icon will appear). 5.
ADVANCED OPERATION ATT (FRONT END ATTENUATOR) The attenuator will reduce all signals (and noise) by 20 dB, and it may be used to make reception more pleasant under extremely noisy conditions. 1. Press the key, then press the key to enter the Set mode. 2. Rotate the DIAL to select the Menu Item labeled (Misc Setup #18: ATT). 3. Press the or key to change the setting from OFF to ON. 4. When you have made your selection, press the PTT key to save the new setting and exit to normal operation. 5.
ADVANCED OPERATION TX BATTERY SAVER The VX-7R also includes a useful Transmit Battery Saver, which will automatically lower the power output level when the last signal received was very strong. For example, when you are in the immediate vicinity of a repeater station, there generally is no reason to use the full 5 Watts of power output in order to achieve full-quieting access to the repeater.
ADVANCED OPERATION AUTOMATIC POWER-OFF (APO) FEATURE The APO feature helps conserve battery life by automatically turning the radio off after a user-defined period of time within which there has been no dial or key activity. The available selections for the time before power-off are 0.5/1/3/5/8 hours, as well as APO Off. The default condition for the APO is OFF, and here is the procedure for activating it: 1. Press the key, then press the key to enter the Set mode. 2.
ADVANCED OPERATION BUSY CHANNEL LOCK-OUT (BCLO) The BCLO feature prevents the radio’s transmitter from being activated if a signal strong enough to break through the “noise” squelch is present. On a frequency where stations using different CTCSS or DCS codes may be active, BCLO prevents you from disrupting their communications accidentally (because your radio may be muted by its own Tone Decoder). The default setting for the BCLO is OFF, and here is how to change that setting: 1.
ADVANCED OPERATION CHANGING THE TX DEVIATION LEVEL In many areas of the world, channel congestion has required that operating channels be closely spaced. In such operating environments, it often is required that operators use reduced deviation levels, so as to reduce the potential for interference to users on adjacent channels. The VX-7R includes a simple method of accomplishing this: 1. Press the key, then press the key to enter the Set mode. 2.
MEMORY MODE The VX-7R provides a wide variety of memory system resources. These include: r Regular Memory Channels, which made up of: ¦ 450 “Standard” memory channels, numbered “1” through “450.” ¦ 12 (USA version) or 11 (EXP version) Home channels, providing storage and quick recall of one prime frequency on each operating band. ¦ 20 sets of band-edge memories also known as “Programmable Memory Scan” channels, labeled “L1/U1” through “L20/U20.” ¦ Nine Memory Groups, labeled “MG1” through “MG9.

This is easily accomplished using the Set mode. 1. 2. 3. 4. 5. 6. 7. 8. Recall the memory channel on which you wish to append a label. Press the key, then press the key to enter the Set mode. Rotate the DIAL to select the Menu Item labeled (Basic Setup #11: NAME SET).
MEMORY MODE REGULAR MEMORY CHANNEL OPERATION Memory Offset Tuning Once you have recalled a particular memory channel, you may easily tune off that channel, as though you were in the “VFO” mode. 1. With the VX-7R in the “MR” (Memory Recall) mode, select the desired memory channel. 2. Now press and hold in the key for 1/2 second. The “MR” indicator will be replaced by one which says “MT” (“Memory Tuning”). 3. Rotate the DIAL, as desired, to tune to a new frequency.
MEMORY MODE REGULAR MEMORY CHANNEL OPERATION Masking Memories There may be situations where you want to “Mask” memories so they are not visible during memory selection or scanning. For example, several memories used only in a city you visit infrequently may be stored, then “Masked” until you visit that city, at which time you can “Unmask” them for normal use. 1. Press the key, if needed, to enter the MR mode. 2.
MEMORY MODE REGULAR MEMORY CHANNEL OPERATION Memory Group Operation Memory Group Assignment 1. Recall the memory channel to be assigned to a Memory Group. 2.

SCANNING The VX-7R allows you to scan just the memory channels, the entire operating band, or a portion of that band. It will halt on signals encountered, so you can talk to the station(s) on that frequency, if you like. Scanning operation is basically the same in each of the above modes. Before you begin, take a moment to select the way in which you would like the scanner to resume scanning after it halts on a signal.
SCANNING VFO SCANNING This mode allows you to scan the entire current operating band. 1. Select the VFO mode by pressing the key, if necessary.. 2. Press the key, then press the key to start scanning. 3. If and when the scanner encounters a signal strong enough to open the squelch, the scanner will halt temporarily; the decimal point of the frequency display will blink during this “Pause” condition. 4. The scanner will then resume according to the Scan-Resume mode selected in the previous section. 5.
SCANNING MEMORY SCANNING Temporary Memory Skip If the scanner repeatedly stops on a channel due to temporary noise or interference, you can temporarily mark it to be skipped (except for Memory Channel “1”). The channel will be skipped until you manually stop the scan (by pressing the PTT switch, for example). To skip a channel temporarily, press the key, then press the key while the scanner has stopped on the channel to be skipped.
SCANNING MEMORY SCANNING Preferential Memory Scan The VX-7R also allows you to set up a “Preferential Scan List” of channels which you can “flag” within the memory system. These channels are designated by a “ ” icon when you have selected them, one by one, for the Preferential Scan List. When you initiate memory scanning on a channel with the “ ” icon appended, only those channels bearing the “ ” icon will be scanned.
SCANNING PROGRAMMABLE (BAND LIMIT) MEMORY SCAN (PMS) This feature allows you to set sub-band limits for either scanning or manual VFO operation. For example, you might with to set up a limit (in North America) of 144.300 MHz to 148.000 MHz so as to prevent encroachment into the SSB/CW “Weak Signal” portion of the band below 144.300 MHz. Here’s how to do this: 1. Set the radio to the VFO mode by pressing the key, if necessary.. 2. Using the techniques learned earlier, store (per the above concept) 144.
SCANNING AUTOMATIC LAMP ILLUMINATION ON SCAN STOP The VX-7R will automatically illuminate the LCD Lamp whenever the scanner stops on a signal; this allows you to see the frequency of the incoming signal better at night. Note that this will, of course, increase the battery consumption, so be sure to switch it off during the day (the default condition for this feature is “ON”). The procedure for disabling the Scan Lamp is: 1. Press the key, then press the key to enter the Set mode. 2.
SPECTRUM ANALYZER OPERATION The Spectrum Analyzer allows viewing operating activity on channels above or below the current operating channel in the VFO mode. The display indicates the relative signal strength on channels immediately adjacent to the current operating frequency. The Spectrum Analyzer feature can only be activated while the VX-7R is operating in the Mono band mode. Two basic operating modes for Spectrum Analyzer are available: 1: In this mode, the transceiver sweeps the current band once.
SMART SEARCH OPERATION The Smart Search feature allows you to load frequencies automatically according to where activity is encountered by your radio.

APPENDIX USING YOUR VX-7R FOR LOW-EARTH-ORBIT FM SATELLITE COMMUNICATION Several Low-Earth-Orbit satellites, such as UO-14 and AO-27, utilize a single-channel FM “repeater in the sky” transponder, affording low-power stations the opportunity to make contacts with other stations thousands of miles away. Communication generally is most easily possible when using a hand-held transceiver (like the VX-7R) in conjunction with a small beam antenna, so as to improve your uplink signal.
