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 FT-270R, 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 FT-270R. Clip the Quick-Draw Belt Clip onto your belt (Figure 2). To install the FT-270R into the Quick-Draw Belt Clip, align the hanger with the QuickDraw Belt Clip, and slide the FT-270R into its slot until a click is heard (Figure 3).
INTERFACE OF PACKET TNCS The FT-270R 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 FT-270R. 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/L] 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) Direct Keypad Frequency Entry The desired operating frequency may be entered directly from the keypad. The first “1” in the frequency does not need to be entered, as it is “assumed” by the microprocessor. To enter a frequency directly, just key in the 10 MHz, 1 MHz, and the kHz digits. Examples: To enter 146.560 MHz, press [4] [6] [5] [6] [0] To enter 146.5625 MHz (12.
OPERATION TRANSMISSION Once you have set up an appropriate frequency inside the 144 MHz Amateur band on which the FT-270R 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 FT-270R operation, let’s learn more about some of the really neat features. KEYBOARD LOCKING To activate the locking feature, press and hold in the [F/L] key for one second. The “ ” icon will appear on the LCD. To cancel locking press and hold in the [F/L] key again for one second. In order to prevent accidental frequency change or inadvertent transmission, various aspects of the FT-270R’s DIAL and keypad may be locked out.
ADVANCED OPERATION KEYPAD/LCD ILLUMINATION Your FT-270R 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 [F/L] key, then press the [0(SET)] key to enter the Set mode. 2. Rotate the DIAL knob to select Set Mode Item 34: RF SQL. 3. Press the [F/L] 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 FT-270R includes a number of features which make repeater operation simple and enjoyable. REPEATER SHIFTS The FT-270R has been configured, at the factory, with the repeater shift set to 600 kHz.
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 [F/L] key, then press the [4(RPT)] key to enable selection of the repeater shift direction. 2. This provides a “short-cut” to Set Mode Item 35: RPT.MOD. 3. Rotate the DIAL knob to select the desired shift among “RPT.–,” “RPT.+,” and “RPT.OFF.” 4.
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 9. If you need to modify the VFO-B (transmit) frequency (for Doppler Shift correction, 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.
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 FT-270R, 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 7. operator if you don’t know the tone frequency). When you have made your selection, press the [F/L] key momentarily 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.
CTCSS/DCS/EPCS OPERATION DCS 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. Switch the DCS off when you’re just tuning around the band! 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.
CTCSS/DCS/EPCS OPERATION EPCS (ENHANCED PAGING & CODE SQUELCH) The FT-270R includes an Enhanced CTCSS tone encoder/decoder and a dedicated microprocessor providing paging and selective calling features. This allows you to place a call to a specific station (Paging), and to receive calls of your choice directed only to you (Code Squelch). The paging and code squelch systems use two pairs of (alternately switched) CTCSS tones which are stored in the pager memories.
CTCSS/DCS/EPCS OPERATION EPCS (ENHANCED PAGING & CODE SQUELCH) Activating the Enhanced Paging & Code Squelch System 1. 2. 3. 4.

With the FT-270R in the “MR” (Memory Recall) mode, select the desired memory channel. Press the [MR/MW(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 FT-270R could be difficult to utilize without some means of organizing them. Fortunately, the FT-270R includes provision for dividing the memories into as many as ten Memory Groups, 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. 2. Select the memory channel containing the frequency data to be moved to the VFO. Press the [MR/MW(SKIP)] key momentarily to activate the “Memory Tune” feature temporarily, then press and hold in the [VFO(PRI)] key for one second.
MEMORY MODE WEATHER BROADCAST CHANNELS The VHF Weather Broadcast Station Memory Channel Bank has been pre-programmed at the factory, for quick selection of NOAA weather information stations. 1. Press and hold in the [1(SQ TYP)] key for one second to recall the Weather Broadcast Memory Bank. 2. Rotate the DIAL knob to select the desired Weather Broadcast channel. 3. If you wish to scan this bank to search for louder CH FREQUENCY CH FREQUENCY 01 162.550 MHz 06 162.500 MHz stations, just press the PTT switch.
SCANNING The FT-270R 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 FT-270R 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/MW(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 FT-270R 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 “u” 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/MW(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. For example, you might wish 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 [VFO(PRI)] key, if necessary. 2.
SCANNING “PRIORITY CHANNEL” SCANNING (DUAL WATCH) The FT-270R’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) WX Channel Priority 1. Recall the memory channel you wish to use as the “Priority” frequency. 2. Now, set the radio for operation on a WX channel by pressing and holding in the [1(SQ TYP)] key for one second. 3. Press the [F/L] key, then press the [VFO(PRI)] key to activate the WX Priority mode. The display will remain on the WX channel frequency, but every five seconds the radio will check the Priority Channel (memory channel) for activity. 4.
SCANNING AUTOMATIC LAMP ILLUMINATION ON SCAN STOP The FT-270R 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 [F/L] key, then press the [0(SET)] key to enter the Set mode. 2.
SCANNING WEATHER ALERT SCAN This feature allows you to check the Weather Broadcast Memory Channels for the presence of the NOAA Alert Tone while operating using VFO scan or Memory channel scan. When the Weather Alert Scan feature is engaged, the FT-270R will check the Weather Broadcast Memory Channels for activity every five seconds while scanning.
EMERGENCY CHANNEL OPERATION The FT-270R 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 [4(RPT)] key for one second.
SMART SEARCH OPERATION The Smart Search feature allows you to load frequencies automatically according to where activity is encountered by your radio.
INTERNET CONNECTION FEATURE The FT-270R can be used to access a “node” (repeater or base station) which is tied into the Vertex Standard WiRES™ (Wide-Coverage Internet Repeater Enhancement System) network, operating in the “SRG” (Sister Radio Group) mode. Details may be found at the WiRES-II Web site: http://www.vxstd.com/en/wiresinfo-en/. This feature may also be used to access other systems, as described below.

Rotate the DIAL knob to set this Set Mode Item to “INT.MEM” (thus activating the “Other Internet Link System” mode).
ARTS™ (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 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. Alert ringers may be activated, if desired.
ARTS™ (AUTOMATIC RANGE TRANSPONDER SYSTEM) 4. Press the [F/L] key momentarily to exit ARTS™ operation and resume normal functioning of the transceiver. ARTS™ constitutes a form of “remote control” operation that may be restricted to certain frequencies. U.S. users should confirm the current status of §97.201(b) of the FCC’s rules governing the 144 MHz band of the Amateur service before utilizing this feature.
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 6 characters. Here’s how to program the CW Identifier: 1. Press the [F/L] key, then press the [0(SET)] key to enter the Set mode. 2. Rotate the DIAL knob to select Set Mode Item 11: CW WRT. 3.
DTMF OPERATION The FT-270R’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 [F/L] key, then press the [9(DTMF)] key to disable the DTMF Autodialer, if necessary.

The “MEM” indication display will appear in the display for a moment. 2.
DTMF PAGER OPERATION (REQUIRES OPTIONAL FTD-7) The FT-270R allows you to utilize a DTMF (Dual-Tone, Multi-Frequency) tone encoder/ decoder, with a dedicated microprocessor providing paging and selective calling features now that you've installed the optional FTD-7 DTMF Paging Unit. This capability allows you to make a call to a specific station (Paging), and to receive calls of your choice directed only to you (Code Squelch).
DTMF PAGER OPERATION (REQUIRES OPTIONAL FTD-7) Activating the DTMF Pager Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode. Rotate the DIAL knob to select Set Mode Item 56: PAGER. Press the [F/L] key momentarily to enable adjustment of this Set Mode Item. 4. Rotate the DIAL knob to select “ON.” 5. Press the PTT switch to save the new setting and activate the DTMF Pager. When the DTMF Pager is activated, the “P” notation will replace the “100 MHz” digit of the frequency display. 6.
DTMF PAGER OPERATION (REQUIRES OPTIONAL FTD-7) When you activate the ANI (Automatic Number Identification) feature during DTMF Pager operation, the DTMF tones stored in ANI memory will automatically be sent whenever you press the PTT switch. When the ANI is received, the LCD will displays the received ANI code after the 3-digit DTMF pager code. Storing the ANI code 1. 2. 3. 4. 5. 6. 7. 8. Press the [F/L] key, then press the [0(SET)] key, to enter the Set mode.
MISCELLANEOUS SETTINGS PASSWORD The FT-270R 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.
MISCELLANEOUS SETTINGS PASSWORD If you forget the password number, you may turn on the transceiver by performing the “All Reset” procedure (see page 65). However, the FT-270R will clear the password, as well as all memories, and will restore all other settings to factory defaults. PROGRAMMING THE KEY ASSIGNMENTS Default FT-270R Set Mode Items have been assigned (at the factory) to the [7(P1)] and [8(P2)] keys.
MISCELLANEOUS SETTINGS RECEIVE BATTERY SAVER SETUP An important feature of the FT-270R 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 FT-270R 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. 2. 3. 4. 5.
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 [F/L] key, then press the [0(SET)] key 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 FT-270R includes a simple method of accomplishing this: Press the [F/L] key, then press the [0(SET)] key to enter the Set mode.
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 FT-270R includes a convenient “Clone” feature, which allows the memory and configuration data from one transceiver to be transferred to another FT-270R. 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. 2. 3. 4. 5. 6. 7. 8. 9. 66 Turn both radios off.
