INSTALLATION OF ACCESSORIES ANTENNA INSTALLATION The supplied antenna provides good results over the entire frequency range of the transceiver. However, for enhanced reception on certain non-Amateur frequencies, you may wish to connect an antenna designed specifically for that frequency range, as the supplied antenna is necessarily a compromise outside the Amateur band, and cannot be expected to provide high performance at all frequencies.
INSTALLATION OF ACCESSORIES BATTERY CHARGING If the battery has never been used, or its charge is depleted, it may be charged by connecting the NC-88 Overnight Battery Charger, as shown in the illustration, to the EXT DC jack. If only 12 ~ 16 Volt DC power is available, the optional E-DC-5B DC Cable (with its cigarette lighter plug) or E-DC-6 DC Cable (plug and wire only) may also be used for charging the battery. A fully-discharged pack will be charged completely in 10 hours.
INSTALLATION OF ACCESSORIES BELT CLIP INSTALLATION Connect the hanger to the rear of the VX-127, with the notch pointing directly up, using the supplied screw (Figure 1). Use only the screw included with the clip to mount the clip to the back of the VX-127. Clip the Quick-Draw Belt Clip onto your belt (Figure 2). To install the VX-127 into the Quick-Draw Belt Clip, align the hanger with the QuickDraw Belt Clip, and slide the VX-127 into its slot until a click is heard (Figure 3).
INTERFACE OF PACKET TNCS The VX-127 may be used for Packet operation, using the optional CT-91 Microphone Adapter (available from your Yaesu dealer) for easy interconnection to commonly-available connectors wired to your TNC. You may also build your own cable, using a fourconductor miniature phone plug, per the diagram below. The audio level from the receiver to the TNC may be adjusted by using the VOL 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-127. 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 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 To set the squelch, press the [F] key, followed by the MONI switch just below the PTT switch on the left side of the transceiver. Now rotate the DIAL (outer knob) to find the lowest setting (“LVL 1” through “LVL 15”) that will just silence the background noise. Do not use a higher setting than necessary, or sensitivity to weak incoming signals will be degraded.
OPERATION FREQUENCY NAVIGATION 2) Scanning Press and hold in either the [ (MHz)] or [ (MHz)] key for one second to initiate upward or downward scanning, respectively (Manual VFO Scan). For scanning within a limited sub-band range, from the VFO mode, press and hold in the [MR(SKIP)] key for one second to begin scanning toward a higher frequency within the previously-defined sub-band (Programmed VFO Scan). Details regarding sub-band setup may be found on page 37.
OPERATION TRANSMISSION Once you have set up an appropriate frequency inside the 144 MHz Amateur band on which the VX-127 can transmit, you’re ready to go on the air! These are the most basic steps; more advanced aspects of transmitter operation will be discussed later. To transmit, press the PTT switch, and speak into the front panel microphone (located in the lower left-hand corner of the speaker grille) in a normal voice level. The TX/BUSY indicator will glow red during transmission.
ADVANCED OPERATION Now that you’re mastered the basics of VX-127 operation, let’s learn more about some of the really neat features. KEYBOARD LOCKING In order to prevent accidental frequency change or inadvertent transmission, various aspects of the VX-127’s DIAL and keypad may be locked out.
ADVANCED OPERATION KEYPAD/LCD ILLUMINATION Your VX-127 includes a reddish illumination lamp which aids in nighttime operation. The reddish 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 lamp for five seconds when you rotate the DIAL knob or press the keypad or any switch (except PTT switch). This is the factory-programmed default setting.
ADVANCED OPERATION RF SQUELCH A special RF Squelch feature is provided on this radio. This feature allows you to set the squelch so that only signals exceeding a certain S-meter level will open the squelch. To set up the RF squelch circuit for operation, use the following procedure: 1. Press the [SET( )EMG] key momentarily to enter the Set mode. 2. Rotate the DIAL knob to select Set Mode Item 34: RF SQL. 3. Press the [F] key momentarily to enable adjustment of this Item. 4.
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-127 includes a number of features which make repeater operation simple and enjoyable. REPEATER SHIFTS The VX-127 has been configured, at the factory, with the repeater shift set to 1.6 MHz, 7.6 MHz, or 5 MHz (USA version).
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 [SET( )EMG] key momentarily to enter the Set mode. 2. Rotate the DIAL knob to select Set Mode Item 35: RPT.MOD. 3. Press the [F] key momentarily to enable adjustment of this Item. 4. Rotate the DIAL knob to select the desired shift among “RPT.
REPEATER OPERATION MANUAL REPEATER SHIFT ACTIVATION 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. To do this, just press the [REV(HOME)] key. You’ll notice that the display has shifted to the repeater uplink frequency. Press the [REV(HOME)] key again to cause operation to revert to normal monitoring of the repeater downlink (output) frequency.
REPEATER OPERATION VFO SPLIT MODE [ ( etc.), just press the VFO PRI)] key, then make the necessary change, then press [VFO(PRI)] key once more to restore VFO-A to the “receive VFO” position. 10. When you have finished with Split operation, re-enter the Set mode, and change Set Mode Item 50: VFO.SPL to “VSP.OFF.” A split frequency pair set up via the VFO Split feature cannot be stored directly into memory. You can, however, store odd frequency pairs using a different (slightly simpler) procedure.
CTCSS/DCS/EPCS 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-127, and is very easy to activate. CTCSS setup involves two actions: setting the Tone Mode and then setting of the Tone Frequency.
CTCSS/DCS/EPCS OPERATION CTCSS OPERATION 10. When you have made your selection, press the [F] key momentarily, then press the PTT switch to save the new settings and exit to normal operation. This is different than the usual method of restoring normal operation, and it applies only to the configuration of the CTCSS/DCS frequencies. 67.0 82.5 100.0 123.0 151.4 171.3 189.9 210.7 250.3 CTCSS TONE FREQUENCY (Hz) 69.3 71.9 74.4 77.0 79.7 85.4 88.5 91.5 94.8 97.4 103.5 107.2 110.9 114.8 118.8 127.3 131.8 136.
CTCSS/DCS/EPCS OPERATION DCS OPERATION tarily, then press the PTT switch to save the new settings and exit to normal operation. Remember that the DCS is an Encode/Decode system, so your receiver will remain muted until a matching DCS code is received on an incoming transmission.
CTCSS/DCS/EPCS OPERATION TONE SEARCH SCANNING You also can press the MONI key during Tone Scanning to listen to the (muted) signal from the other station. When you release the MONI key, Tone Scanning will resume after about a second. Tone Scanning works either in the VFO or Memory modes. EPCS (ENHANCED PAGING & CODE SQUELCH) The VX-127 includes an Enhanced CTCSS tone encoder/decoder and a dedicated microprocessor providing paging and selective calling features.
CTCSS/DCS/EPCS OPERATION EPCS (ENHANCED PAGING & CODE SQUELCH) The VX-127 does not recognize the order of the 1st tone and the 2nd tone. In other words, for example, the VX-127 considers both CTCSS pairs “10, 35” and “35, 10” to be identical. Activating the Enhanced Paging & Code Squelch System Press the [SET( )EMG] key momentarily to enter the Set mode. Rotate the DIAL knob to select Set Mode Item 44: SQL.TYP. Press the [F] key momentarily to enable adjustment of this Item.

Rotate the DIAL knob to select Set Mode Item 43: SPLIT. 3. Press the [F] key momentarily to enable adjustment of this Set Mode Item. 4. Rotate the DIAL knob to select ON (to enable the Split Tone feature). 5. Press the PTT switch momentarily to save the new setting and exit to normal operation.
MEMORY MODE The VX-127 provides a wide variety of memory system resources. These include: 200 “Standard” memory channels, numbered “1” through “200.” A “Home” channel, providing storage and quick recall of one prime frequency. 10 sets of band-edge memories, also known as “Programmable Memory Scan” channels, labeled “L1/U1” through “L10/U10.” 10 Memory Banks, labeled “BANK 1” through “BANK10.” Each Memory Bank can be assigned up to 200 channels from the “standard” memory channels.
MEMORY MODE MEMORY RECALL While operating in the VFO mode, press the [MR(SKIP)] key to enter the Memory mode. 2. Rotate the DIAL knob to select the desired channel. 3. To return to the VFO mode, press the [VFO(PRI)] key. 1. HOME CHANNEL MEMORY A special one-touch “HOME” channel is available, to allow quick recall of a favorite operating frequency. Home Channel storage is simple to accomplish: 1.
MEMORY MODE LABELING MEMORIES You may wish to append an alpha-numeric “Tag” (label) to a memory or memories, to aid in recollection of the channel’s use (such as a club name, etc.). This is easily accomplished using the Set Mode. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. Recall the memory channel on which you wish to append a label. Press the [SET( )EMG] key momentarily to enter the Set mode. Rotate the DIAL knob to select Set Mode Item 29: NM WRT.
MEMORY MODE 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-127 in the “MR” (Memory Recall) mode, select the desired memory channel. 2. Press the [MR(SKIP)] key momentarily to activate the “Memory Tuning” feature. The Memory Channel number will be replaced by “tun.
MEMORY MODE MEMORY BANK OPERATION The large number of memories available in the VX-127 could be difficult to utilize without some means of organizing them. Fortunately, the VX-127 includes provision for dividing the memories into as many as ten Memory Banks, so you can categorize the memories in a manner convenient to you. Assigning Memories to a Memory Bank 1. Recall the memory channel to be assigned to a Memory Bank. 2.
MEMORY MODE MOVING MEMORY DATA TO THE VFO Data stored on memory channels can easily be moved to the last selected VFO, if you like. 1. Select the memory channel containing the frequency data to be moved to the VFO. 2. Press the [MR(SKIP)] key momentarily to activate the “Memory Tune” feature temporarily, then press and hold in the [VFO(PRI)] key for one second.
NOTE VX-127 OPERATING MANUAL 35
SCANNING The VX-127 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 The VX-127 provides two VFO scanning functions: “Manual VFO Scanning” and “Programmed VFO Scanning.” Manual VFO Scan 1. Select the VFO mode by pressing the [VFO(PRI)] key, if necessary. 2. Press and hold in either the [ (MHz)] or [ (MHz)] key for one second to initiate upward or downward scanning, respectively. 3.
SCANNING MEMORY SCANNING Memory scanning is similarly easy to initiate: 1. Select the Memory mode by pressing the [MR(SKIP)] key, if necessary. 2. Press and hold in either the [ (MHz)] or [ (MHz)] key for one second to initiate upward or downward scanning, respectively. 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.
SCANNING MEMORY SCANNING Preferential Memory Scan The VX-127 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 blinking “ ” icon when you have selected them, one by one, for the Preferential Scan List. When you initiate memory scanning, beginning on a channel with the blinking “ ” icon appended, only those channels bearing the blinking “ ” icon will be scanned.
SCANNING MEMORY SCANNING Memory Bank Scan When the Memory Bank feature is engaged, the scanner sweeps only memory channels in the current Memory Bank. However, if the Memory Bank Link Scan feature is enabled, you may sweep the memory channels in several Memory Banks which you have selected. To enable the Memory Bank Link Scan feature: 1. Set the radio to the Memory mode by pressing the [MR(SKIP)] key, if necessary. 2.
SCANNING PROGRAMMABLE (BAND LIMIT) MEMORY SCAN (PMS) This feature allows you to set sub-band limits for either scanning or manual VFO operation. Here’s how to do this, using the frequencies 435.100 MHz and 439.900 MHz as band limits: 1. 2. 3. 4. 5. 6. Set the radio to the VFO mode by pressing the [VFO(PRI)] key, if necessary. Using the techniques learned earlier, store (per the above concept) 435.100 MHz into Memory Channel #L01 (the “L” designates the Lower sub-band limit). Likewise, store 439.
SCANNING “PRIORITY CHANNEL” SCANNING (DUAL WATCH) The VX-127’s scanning features include a two-channel scanning capability which allows you to operate on a VFO or Memory channel, while periodically checking a user-defined Memory Channel for activity. If a station is received on the Memory Channel which is strong enough to open the Squelch, the scanner will pause on that station in accordance with the Scan-Resume mode set via Set Mode Item 32: RESUME. See page 36.
SCANNING “PRIORITY CHANNEL” SCANNING (DUAL WATCH) VFO-VFO Dual Watch 1. Press the [VFO(PRI)] key to switch the VFO mode, if needed. 2. Press the [F] key, then press and hold in the [VFO(PRI)] key for one second. The VX127 will now periodically change from VFO-A frequency to the VFO-B frequency, checking for activity on each VFO for 0.2 second interval. 3. Press the [VFO(PRI)] key to disable the VFO-VFO Dual Watch.
SCANNING AUTOMATIC LAMP ILLUMINATION ON SCAN STOP The VX-127 will automatically illuminate the LCD/Keypad 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 [SET( )EMG] key momentarily to enter the Set mode. 2.
NOTE VX-127 OPERATING MANUAL 45
EMERGENCY FEATURE EMERGENCY CHANNEL OPERATION The VX-127 includes an “Emergency” feature which may be useful if you have someone monitoring on the same frequency as your transceiver’s “Home” channel. See page 30 for details on setting up the Home channel. The “Emergency” feature is activated by pressing and holding in the [SET( )EMG] key for one second.
EMERGENCY FEATURE EMERGENCY AUTOMATIC ID (EAI) FEATURE The Emergency Automatic ID (EAI) feature can be used for searching for persons who are incapacitated in disasters like earthquakes, especially search-and-rescue personnel who may have become injured in a debris field.
EMERGENCY FEATURE EMERGENCY AUTOMATIC ID (EAI) FEATURE The Emergency Automatic ID (EAI) Feature requires that you (1) store the CTCSS Tone Pair into the Receiving Pager Memory (see page 26 for procedure), and (2) store the desired coordination frequency into Memory Channel “200” (see page 29 for procedure). To enable this feature: 1. Press the [SET( )EMG] key momentarily to enter the Set mode. 2. Rotate the DIAL knob to select Set Mode Item 53: EAI. 3.
SMART SEARCH OPERATION The Smart Search feature allows you to load frequencies automatically according to where activity is encountered by your radio.

Rotate the DIAL knob to select Set Mode Item 54: ANI.WRT.
MISCELLANEOUS SETTINGS PASSWORD The VX-127 provides a security password feature which can minimize the chance that your transceiver could be used by an unauthorized party. When the password feature is activated, the radio will ask for the four digit password to be entered when the radio is first turned on. You must enter the four digit password from the keypad. If the wrong password is entered, the microprocessor will shut down the radio automatically. To enter the password , use the following procedure: 1.
MISCELLANEOUS SETTINGS PASSWORD To Activate the Password feature: 1. Press the [SET( )EMG] key momentarily to enter the Set mode. 2. Rotate the DIAL knob to select Set Mode Item 30: PSWD. 3. Press the [F] key momentarily to enable adjustment of this Item. 4. Rotate the DIAL knob to set this Set Mode Item to “PWD. ON.” 5. When you have made your selection, press the PTT switch to save the new setting and exit to normal operation. 6.
MISCELLANEOUS SETTINGS RECEIVE BATTERY SAVER SETUP An important feature of the VX-127 is its Receive Battery Saver, which “puts the radio to sleep” for a time interval, periodically “waking it up” to check for activity. If somebody is talking on the channel, the VX-127 will remain in the “active” mode, then resume its “sleep” cycles. This feature significantly reduces quiescent battery drain, and you may change the amount of “sleep” time between activity checks using the Set Mode: 1.
MISCELLANEOUS SETTINGS DISABLING THE TX/BUSY INDICATOR Further battery conservation may be accomplished by disabling the TX indicator while transmitting and disabling the BUSY indicator while receiving a signal. Use the following procedure: 1. Press the [SET( )EMG] key momentarily to enter the Set mode. 2. Rotate the DIAL knob to select Set Mode Item 8: BSY.LED if you wish to disable the BUSY indicator or Set Mode Item 48: TX.LED if you wish to disable the TX indicator. 3.
MISCELLANEOUS SETTINGS TRANSMITTER TIME-OUT TIMER (TOT) The TOT feature provides a safety switch which limits transmission time to a pre-programmed value. This will promote battery conservation by not allowing you to make excessively-long transmissions, and in the event of a stuck PTT switch (perhaps if the radio or a Speaker/Mic is wedged between car seats) it can prevent interference to other users as well as battery depletion.
MISCELLANEOUS SETTINGS DCS CODE INVERSION The DCS system was first introduced in the commercial LMR (Land Mobile Radio) service, where it is now in widespread use. DCS is sometime referred to by its different proprietary names, such as DPL® (Digital Private Line®, a registered trademark of Motorola, Inc.). DCS uses a codeword consisting of a 23-bit frame, transmitted (subaudible) at a data rate of 134.4 bps (bit/sec).
MISCELLANEOUS SETTINGS 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-127 includes a simple method of accomplishing this: 1. Press the [SET( )EMG] key momentarily to enter the Set mode. 2.
RESET PROCEDURES In the event of erratic operation of the transceiver, it is possible that data on the microprocessor may have become corrupted. While this is a highly unusual situation, the only path to recovery may involve resetting of the microprocessor. Here’s how to do this: 1. Turn the radio off. 2. Press and hold in the MONI switch (just below the PTT switch) while turning the radio on. 3.
CLONING The VX-127 includes a convenient “Clone” feature, which allows the memory and configuration data from one transceiver to be transferred to another VX-127. This can be particularly useful when configuring a number of transceivers for a public service operation. Here is the procedure for Cloning one radio’s data to another: 1. Turn both radios off. 2. Connect the user-constructed cloning cable and two optional CT-91 Microphone Adapters (one on each end) between the MIC/SP jacks of the two radios. 3.
