![VX-150 OPERATING MANUAL4FRONT PANELS•SpeakerThe internal speaker is located directly below the display.‚ MicThe internal microphone is located at the bottom right-hand corner of the speaker.ƒKeypadThese sixteen keys select the various operating features of the transceiver during re-ception, and generate DTMF (Dual Tone Multi Frequency) tone pairs during transmis-sion. One or two beeps will sound whenever one of the keys is pressed (if the beeper isactive). The labels on the faces of the keys indicate their primary functions, while thelabels above fifteen of the keys indicate alternate functions, which are activated bypressing the [F/W] key first, and then another key within five seconds. When referringto alternate key functions in this manual, we show the alternate key label followed bythe primary label in parentheses ( ). Primary key functions are referred to by the labelson the keyfaces.Remember to press the [F/W] key first (momentarily, unless otherwise indicated) whenyou want to use an alternate key function. All key functions are described in the “Op-eration” section, and summarized on the “VX-150 Operator’s Quick Reference Card.”Controls & Connectors](https://usermanual.wiki/Yaesu-Musen/VX-110/User-Guide-72686-Page-4.png)
![VX-150 OPERATING MANUAL 7To remove the battery, turn the radio off and remove any protective cases. Open the Bat-tery Pack latch on the bottom of the radio, then slide the battery downward and out fromthe radio while unfolding the Belt Clip.Do not attempt to open any of the rechargeable Ni-Cd packs, as they could explode ifaccidentally short-circuited.If the battery has never beenused, or its charge is de-pleted, it may be charged byconnecting the NC-72A/B/C/F/U Battery Charger, asshown in the illustration, tothe EXT DC jack. If only 12~ 16 Volt DC power is avail-able, the optional E-DC-5B or E-DC-6 DC Adapter (with its cigarette lighter plug) mayalso be used for charging the battery, as shown in the illustration.INSTALLATION OF FBA-25 (Option) ALKALINE BATTERY CASEThe optional FBA-25 Battery Case allows receive monitoring using six “AA” size Alka-line batteries. Alkaline batteries can also be used for transmission in an emergency, butpower output will only be 300 mW, and battery life will be shortened dramatically.To Install Alkaline Batteries into the FBA-25rSlide the batteries into the FBA-25 as shown in the illustration, with the Negative [–]side of the batteries touching the spring connections inside the FBA-25.rUnlock the bottom plate by pushing the latch in the “Open” direction.rInstall the FBA-25 as shown in the illustration, with the [+] side facing the bottom ofthe transceiver.rRe-lock the bottom plate by carefully pressing the latch cover back into its normaloperating position.The FBA-25 does not provide connections for charging, since Alkaline cells cannot be re-charged. Therefore, the NC-72A/B/C/F/U, E-DC-5B, or E-DC-6 may safely be con-nected to the EXT DC jack when the FBA-25 is installed.Notes:mThe FBA-25 is designed for use only with AA-type Alkaline cells.mIf you do not use the VX-150 for a long time, remove the Alkaline batteries from theFBA-25, as battery leakage could cause damage to the FBA-25 and/or the trans-ceiver.Installation & Accessories](https://usermanual.wiki/Yaesu-Musen/VX-110/User-Guide-72686-Page-7.png)
![VX-150 OPERATING MANUAL 9Note that while receiving, one or more bargraph segments may appear along the bottom ofthe display, indicating signal strength on the receiving frequency. This indication is notaffected by the squelch setting, so even squelched signals may have some indication. If younotice more than one or two bargraph segments appearing while the squelch is still closed,try reducing the squelch control setting (if you want to hear weak signals).The Monitor switch on the USA versions (just above the PTT switch) allows you to checkfor channel activity beneath the squelch level and to adjust the volume without having toadjust the squelch: just press the Monitor switch and the squelch will open.FREQUENCY NAVIGATIONPress the [VFO(PRI)] button, if necessary, to select the VFO mode. The VX-150 has twovfos, labelled “A” and “B” either of which can be used for all of the procedures describedin this manual. You can change vfos with the [VFO(PRI)] button at any time.You have several ways to tune the VX-150: in selectable channel steps or 1 MHz stepswith the [s] / [t] keys or DIAL knob, and direct keypad frequency entry.Use the DIAL knob to tune the displayed VFO frequency at the current channel step rate.You can also press the [s] / [t] keys momentarily to do this, but if you press an [s] or[t] key for more than 1/2-second scanning will start. This is described later, so for now,just press an [s] / [t] key again to stop (if you have to).To change the MHz range of the VFO, you can press the [F/W] key followed by an [s] or[t] key (or turn the DIAL knob). Note the beeps when using the [s] / [t] keys: whenmoving up, and when moving down. When done press [F/W] again, or just wait five sec-onds.You can also enter a frequency directly just by keying in the 1 MHz and the kHz digits. Ifyou are using 5 or 10 kHz steps enter five digits. Otherwise just four digits will do. Partialentries can be cancelled with the [VFO(PRI)] key.Examples:To enter 146.5200 MHz, press à à à à To enter 146.5000 MHz, press à à à Operation](https://usermanual.wiki/Yaesu-Musen/VX-110/User-Guide-72686-Page-9.png)

![VX-150 OPERATING MANUAL12REPEATER OPERATIONThe ARS (Automatic Repeater Shift) feature in the VX-150 provides repeater shift of thetransmit frequency whenever you are tuned to a standard repeater subband (see diagrambelow). When enabled, a small “–” or “+” displayed above the upper left-hand corner ofthe display that repeater shift is active, and closing the push-to-talk switch changes thedisplay to the (shifted) transmit frequency.Automatic Repeater Shift (ARS)The VX-150 provides a convenient Automatic Repeater Shift feature, which causes theappropriate repeater shift to be automatically applied whenever you tune into the desig-nated repeater sub-bands in your country. These sub-bands are shown below.If the ARS feature does not appear to be working, you may have accidentally disabled it.To re-enable ARS:•Press the [F/W] key, then immediately press the [0(SET)] key to enter the Set mode.‚Rotate the DIAL to select Menu Item #2 (“ARSARSARSARSARS”).ƒPress the [F/W] key to enable modification of the current setting.„Now rotate the DIAL to select “ON” (to enable Automatic Repeater Shift).…Press the PTT key to save the new setting and exit to normal operation.Manual Repeater Shift ActivationIf the ARS feature has been disabled, or if you need to set a repeater shift other than thatestablished by the ARS, you may set the direction of the repeater shift manually.To do this, press the [F/W] key, then press the [4(RPT)] key. This provides a “Shortcut” toMenu #3 (“RPTRPTRPTRPTRPT”). Rotate the DIAL, and you will see that the “–” or “+” icon appears at theupper of the LCD (when no icon is present, “Simplex” operation - transmit and receive onthe same frequency - has been selected, and the LCD will indicate “SIMPSIMPSIMPSIMPSIMP” in this case).When the desired shift direction has been selected, press the PTT key momentarily to saveyour new setting and exit.Advanced Operation](https://usermanual.wiki/Yaesu-Musen/VX-110/User-Guide-72686-Page-12.png)

![VX-150 OPERATING MANUAL14CTCSS OPERATIONMany repeater systems require that a very-low-frequency audio tone be superimposed onyour FM carrier in order to activate the repeater. This helps prevent false activation of therepeater by radar or spurious signals from other transmitters. This tone system, called“CTCSS” (Continuous Tone Coded Squelch System), is included in your VX-150, and isvery easy to activate.CTCSS setup involves two actions: setting the Tone Frequency and then setting of theTone Mode. These actions are set up by using the [1(SQ TYP)] and [2(CODE)] keys, orMenu Items #25 and #26.•Press the [F/W] key, then immediately press the [1(SQ TYP)] key. This provides a“Short-cut” to Menu #25 (“SQL TYPSQL TYPSQL TYPSQL TYPSQL TYP”).‚Rotate the DIAL so that “TTTTT” appears on the display; this activates the CTCSS Encoder,which allows repeater access.ƒYou may notice an additional “DCSDCSDCSDCSDCS” icon appearing while you rotate the DIAL in thisstep. We’ll discuss the Digital Code Squelch system shortly.„Rotation of the DIAL in step ‚ above will occasionally cause “SQSQSQSQSQ” to appear adjacentto the “TTTTT” icon. When “TONE SQLTONE SQLTONE SQLTONE SQLTONE SQL” appears, this means that the Tone SQuelch systemis active, which mutes your VX-150’s receiver until it receives a call from anotherradio sending out a matching CTCSS tone. This can help keep your radio quiet until aspecific call is received, which may be helpful while operating in congested areas.…When you have made your selection of the CTCSS tone mode, press the PTT.†Press the [F/W] key, then immediately press the [2(CODE)] key. This provides a “Short-cut” to Menu #26 (“TN SETTN SETTN SETTN SETTN SET”).‡This Menu selection allows setting of the CTCSS tone frequency to be used.ˆRotate the DIAL until the display indicates the Tone Frequency you need to be using(ask the repeater owner/operator if you don’t know the tone frequency).‰Press the [F/W] key to save the new settings and exit to normal operation.CTCSS TONE FREQ UEN CY (Hz)67.0 69.3 71.9 74.4 77.0 79.7 82.5 85.488.5 91.5 94.8 97.4 100.0 103.5 107.2 110.9114.8 118.8 123.0 127.3 131.8 136.5 141.3 146.2151.4 156.7 162.2 167.9 173.8 179.9 186.2 192.8203.5 210.7 218.1 225.7 233.6 241.8 250.3 -Advanced Operation](https://usermanual.wiki/Yaesu-Musen/VX-110/User-Guide-72686-Page-14.png)
![VX-150 OPERATING MANUAL 15DCS OPERATIONAnother form of tone access control is Digital Code Squelch, or DCS. It is a newer, moreadvanced tone system which generally provides more immunity from false paging thandoes CTCSS. The DCS Encoder/Decoder is built into your VX-150, and operation is verysimilar to that just described for CTCSS. Your repeater system may be configured forDCS; if not, it is frequently quite useful in Simplex operation if your friend(s) use trans-ceivers equipped with this advanced feature.Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS and thatyou select a tone code.•Press the [F/W] key, then immediately press the [1(SQ TYP)] key. This provides a“Short-cut” to Menu #25 (“SQL TYPSQL TYPSQL TYPSQL TYPSQL TYP”).‚Rotate the DIAL until “DCSDCSDCSDCSDCS” appears on the display; this activates the DCS Encoder/Decoder.ƒWhen you have made your selection of the DCS mode, press the PTT.„Press the [F/W] key, then immediately press the [2(CODE)] key. This provides a “Short-cut” to Menu #26 (“TN SETTN SETTN SETTN SETTN SET”).…Rotate the DIAL to select the desired DCS Code (a three-digit number). Ask the re-peater owner/operator if you don’t know DCS Code; if you are working simplex, justset up the DCS Code to be the same as that used by your friend(s).†When you have made your selection, press the [F/W] key to save the new settings andexit to normal operation.Remember that the DCS is an Encode/Decode system, so your receiver will remain muteduntil a matching DCS code is received on an incoming transmission.

![VX-150 OPERATING MANUAL16TONE SEARCH SCANNINGIn operating situations where you don’t know the CTCSS or DCS tone being used byanother station or stations, you can command the radio to listen to the incoming signal andscan in search of the tone being used. Two things must be remembered in this regard:mYou must be sure that your repeater uses the same tone type (CTCSS vs. DCS).mSome repeaters do not pass the CTCSS tone; you may have to listen to the station(s)transmitting on the repeater uplink (input) frequency in order to allow Tone SearchScanning to work.To scan for the tone in use:•Set the radio up for either CTCSS or DCS Decoder operation (see the previous discus-sion). In the case of CTCSS, “T SQT SQT SQT SQT SQ” will appear on the display; in the case of DCS,“DCSDCSDCSDCSDCS” will appear on the display.‚Press the [F/W] key, then immediately press the [2(CODE)] key to select the “TNTNTNTNTNSETSETSETSETSET” Menu item (when TONE SQL is selected) or “DCS SETDCS SETDCS SETDCS SETDCS SET” (during DCS opera-tion).ƒPress and hold in the [s] or [t] key to start scanning for the incoming CTCSS or DCStone/code.„When the radio detects the correct tone or code, it will halt on that tone/code, and audiowill be allowed to pass. Press the [F/W] key to lock in that tone/code, and exit tonormal operation.If the Tone Scan feature does not detect a tone or code, it will continue to scan indefi-nitely. When this happens, it may be that the other station is not sending any tone. Youcan press the PTT switch to halt the scan at any time.You also can press the MONI key during Tone Scanning to listen to the (muted) signalfrom the other station. When you release the MONI key, Tone Scanning will resumeafter about a second.Tone Scanning works either in the VFO or Memory modes.Advanced Operation](https://usermanual.wiki/Yaesu-Musen/VX-110/User-Guide-72686-Page-16.png)
![VX-150 OPERATING MANUAL 17CTCSS/DCS BELL OPERATIONDuring CTCSS Decode or DCS operation, you may set the VX-150 up such that a ringing“Bell” sound alerts you to the fact that a call is coming in. Here is the procedure for activat-ing the Bell will ring in accordance with this programming.•Set the transceiver up for CTCSS Decode (“TONE SQL” or DCS operation, as de-scribed previously.‚Adjust the operating frequency to the desired channel.ƒPress the [F/W] key, then press the [0(SET)] key to activate the Set mode.„Rotate the DIAL to select Menu Item #18 (“BELLBELLBELLBELLBELL”).…Press the [F/W] key to enable adjustment of the Bell ringer.†Rotate the DIAL to set the desired number of rings of the Bell.

![VX-150 OPERATING MANUAL 23DTMF CODE SQUELCH (REQUIRES OPTIONAL FVP-25)The code squelch system use 3-digit numeric codes (000000000000000 ~ 999999999999999), transmitted as DTMF(dual, audible) tone pairs.There are twelve code memories numbered [1] ~ [9], [A] and [D], which store 3-digitDTMF paging codes (these are independent and unrelated to the channel memories and theVFOs).The code squelch mode is very simple: both you and the other station communicate usingthe same 3-digit DTMF sequence, sent automatically at the start of every transmission.Your receiver normally remains silent to all signals that are not prefixed by your selected3-digit code. When you receive the matching tone sequence, your squelch opens and staysopen until a few seconds after the end of their transmission.In the code squelch mode, you must first store and then manually select the one CodeMemory holding the 3-digit DTMF code required to open your squelch (as described onthe following pages). Also, in the code squelch mode, Code Memories [1] ~ [9] alwaysfunction the same.Codes of up to nine other stations can be stored in these memories. These are stations youexpect to frequently contact, and whose page calls you also want to receive. Members of acommon group or club usually share a common 3-digit paging code so that they can bepaged simultaneously.Remember, with Code Squelch operation (but not with DTMF Paging), you can only re-ceive a call on the currently selected Code Memory, and the display does not change whena call is received. So for code squelch, as mentioned before, the Code Memory distinctiondoes not apply (although you must still store the 3-digit Code Memories).Storing Code MemoriesThe first thing to do before using Code Squelch is to store 3-digit code in Code Memory:•Press the [F/W] key, then press the [0(SET)] key to enter the Set mode.‚Rotate the DIAL to select Menu Item #40 (“PG CODEPG CODEPG CODEPG CODEPG CODE”).ƒPress the [F/W] key to enable adjustment of this Menu item.„Rotate the DIAL to select the Code Memories register into which you wish to store thiscode string.…Press the [F/W] key, then press the [F/W] key to begin Code Memories entry into theselected register.†Rotate the DIAL to select Key in the DTMF digits you wish to store into this register.‡Press the PTT switch to save the setting.

![VX-150 OPERATING MANUAL24You can use the same procedure to store the Memory Codes of other individuals or groupsin Code Memories [1] ~ [9].Although up to nine Code Memories can be stored, you might only need a few of them tocall your friends or a specific group. Likewise, you’ll probably only want your radio torespond to pages directed to you (or maybe your group or club’s code). The followingexplains how to temporarily inhibit unused Code Memories.Page Code InhibitDuring the Code Memory storage procedure above, when storing Code Memories [1] ~[9], you have an opportunity to decide whether your transceiver should respond to incom-ing paging calls on a particular Memory Code.To activate Code setting:•Press the [F/W] key, then press the [0(SET)] key, to enter the Set mode.‚Rotate the DIAL to select Menu #40 (“PG CODEPG CODEPG CODEPG CODEPG CODE”).ƒPress the [F/W] key, then rotate the DIAL to select the Code Memories register intowhich you wish to this code string.„Press the [F/W] key, rotate the DIAL to set the function ON.…When you have made your selection, press the PTT key to save the new setting and exitto Set mode.DTMF Code Squelch OperationAs described earlier, with DTMF code squelch activated (CODE displayed), your squelchwill not open until you receive the proper 3-digit DTMF code according to the selectedcode memory. Likewise, each time you press the PTT, the same 3-digit code is automati-cally sent to open the other station’s DTMF coded squelch.With the Code Squelch activated in this manner, you will hear three DTMF code digitstransmitted when you press your PTT switch. These are the digits stored in the CodeMemory currently selected, and they will open the squelch of the other station.Therefore, at the start of each transmission, you must wait a second or two after pressingthe PTT switch for the DTMF code to be sent (you will hear it in your speaker).When you finish your conversation, if you need to reactivate DTMF Code Paging, pressCODE (PAGE) until PAGE is again displayed.Advanced Operation](https://usermanual.wiki/Yaesu-Musen/VX-110/User-Guide-72686-Page-24.png)

![VX-150 OPERATING MANUAL 27ARTS (AUTOMATIC RANGE TRANSPONDER SYSTEM)The ARTS feature uses DCS signaling to inform both parties when you and another ARTS-equipped station are within communications range. This may be particularly useful duringSearch-and Rescue situations, where is important to stay in contact with other members ofyour group.Both stations must set up their DCS codes to the same code number, then activate theirARTS feature using the command appropriate for their radio. Alert ringers may be acti-vated, if desired.Whenever you push the PTT, or every 25 (or 15) sec-onds after ARTS is activated, your radio will transmita signal which includes a (subaudible) DCS signal forabout 1 second. If the other radio is in range, the beeperwill sound (if enabled) and the display will show “INININININRNGRNGRNGRNGRNG” as opposed to the out of range display “OUTOUTOUTOUTOUTRNGRNGRNGRNGRNG” in which ARTS operation begins.Whether you talk or not, the polling every 15 or 25 seconds will continue until you de-activate ARTS. Every 10 minutes, moreover, you can have your radio transmit your callsignvia CW, so as to comply with identification requirements. When ARTS is de-activated,DCS will also be deactivated (if you were not using it previously in non-ARTS operation).If you move out of range for more than one minute (four pollings), your radio will sensethat no signal has been received, three beeps will sound, and the display will revert to“OUT RNGOUT RNGOUT RNGOUT RNGOUT RNG.” If you move back into range, your radio will again beep, and the display willchange back to the “IN RNGIN RNGIN RNGIN RNGIN RNG” indication.You must terminate ARTS in order to resume normal operation.

![VX-150 OPERATING MANUAL38The Smart Search feature allows you to load frequencies automatically according to whereactivity is encountered by your radio. When Smart Search is engaged, the transceiver willsearch above and below your current frequency, storing active frequencies as it goes (with-out stopping on them even momentarily); these frequencies are stored into a special SmartSearch memory bank, consisting of 31 memories (15 above the current frequency, 15 be-low the current frequency, plus the current frequency itself).Two basic operating modes for Smart Search are available:SINGLESINGLESINGLESINGLESINGLE: In this mode, the transceiver will sweep the current band once in each direc-tion starting on the current frequency. All channels where activity is presentwill be loaded into the Smart Search memories; whether or not all 31 memo-ries are filled, the search will stop after one sweep in each direction.CONTINUECONTINUECONTINUECONTINUECONTINUE: In this mode, the transceiver will make one pass in each direction as withOne-Shot searching; if all 31 channels are not filled after the first sweep,however, the radio will continue sweeping until they are all filled.Setting the Smart Search Mode•Press the [F/W] key, then press the [0(SET)] key, to enter the Set mode.‚Rotate the DIAL to select Menu #31 (“SMT MODSMT MODSMT MODSMT MODSMT MOD”).ƒPress the [F/W] key to enable changing of this Menu item.„Rotate the DIAL to select the desired Smart Search mode (see above).…When you have made your selection, press the PTT key to save the new setting and exitto normal operation.Storing Smart Search Memories•Set the radio to the VFO mode.‚Press the [F/W] key, then press the [8(P2)] key.ƒPress the [s] or [t] key to begin the Smart Search scanning.„As active channels are detected, you will observe the number of “loaded” channelsincreasing in the regular memory channel window.…Depending on the mode you set for Smart Search operation (SINGLE or CONTINUE),the Smart Search scan will eventually terminate, and the LCD will revert to SmartSearch Memory Channel 0.†To recall Smart Search memories, rotate the DIAL to choose from among the SmartSearch memories.‡To return to normal operation, Press the [VFO(PRI)] key.Smart Search is a great tool when visiting a city for the first time.
