To change the configuration of this key, use Menu Item “Misc. Setup #2 [HOM/REV]. See page ??. CTCSS/DCS 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-8900, 13 Vertex Standard Co., Ltd.

FCC ID: K66FT-8900R OPERATING M ANUAL and is very easy to activate. R.F. Says: CTCSS setup involves two actions: setting the Tone Frequency and then setting of the Tone Mode. These actions are set up by using the Set mode #42 (TONE M) and #41 (TONE F). 1. Press the [SET] key momentarily to enter the Set mode. 2. Rotate the “Main” band DIAL knob to select Menu #42 (TONE M). 3. Press the “Main” band DIAL knob momentarily, then rotate the “Main” DIAL knob so that “ENC” appears on the display; this activates the CTCSS Encoder, which allows repeater access. R.F. Says: You may notice an additional “DCS” icon appearing while you rotate the “Main” DIAL knob in this step. We’ll discuss the Digital Code Squelch system shortly. 4. Rotate the “Main” DIAL knob one click clockwise in step “3” above will occasionally cause “ENC.DEC.” When “ENC.DEC” appears, this means that the Tone Squelch system is active, which mutes your FT-8900’s receiver until it receives a call from another radio sending out a matching CTCSS tone. This can help keep your radio quiet until a specific call is received, which may be helpful while operating in congested areas. 5. When you have made your selection of the CTCSS tone mode, press the “Main” DIAL knob momentarily then rotate the “Main” DIAL knob one click counter- clockwise to select Menu #41 (TONE F). This Menu selection allows setting of the CTCSS tone frequency to be used. 6. Press “Main” DIAL knob momentarily to enable the adjustment of the CTCSS frequency. 7. Rotate the “Main” DIAL knob until the display indicates the Tone Frequency you need to be using. 8. When you have made your selection, press and hold in the “Main” DIAL knob for 1/2 second to save the new setting and exit to normal operation. R.F. Says: 1) Your repeater may or may not re-transmit a CTCSS tone - some systems just use CTCSS to control access to the repeater, but don’t pass it along when transmitting. If the S-Meter deflects, but the FT-8900 is not passing audio, repeat steps “1” through “4” above, but rotate the “Main” DIAL knob so that “ENC” appears - this will allow you to hear all traffic on the channel being received. 14 Vertex Standard Co., Ltd.

FCC ID: K66FT-8900R OPERATING M ANUAL 2) You may select the Tone Squelch mode (ENC, ENC.DEC, or DCS) on the “Main” band by the microphone’s [P3] key. 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 FT-8900, 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. R.F. Says: Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS and that you select a tone code. 1. Press the [SET] key momentarily to enter the Set mode. 2. Rotate the “Main” band DIAL knob to select Menu #42 (TONE M). 3. Press the “Main” band DIAL knob momentarily, then rotate the “Main” DIAL knob until “DCS” appears on the display; this activates the DCS Encoder/Decoder. 4.

When you have made your selection, press and hold in the “Main” DIAL knob for 1/2 second to save the new setting and exit to normal operation. R.F. Says: 1) 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! 2) You may select the Tone Squelch mode (ENC, ENC.DEC, or DCS) on the “Main” band by the microphone’s [P3] key. 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). 15 Vertex Standard Co., Ltd.

FCC ID: K66FT-8900R OPERATING M ANUAL  Some 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 Search Scanning to work. To scan for the tone in use: 1. Set the radio up for either CTCSS or DCS Decoder operation (see the previous discussion). In the case of CTCSS, “ENC DEC” will appear on the display; in the case of DCS, “DCS” will appear on the display. 2. Press the [SET] key momentarily to enter the Set mode. 3. Rotate the “Main” DIAL knob select the Menu #41 (TONE F) when CTCSS is selected, or Menu #10 (DCS.COD) during DCS operation. 4.

Scanning The FT-8900 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. 19 Vertex Standard Co., Ltd.

FCC ID: K66FT-8900R OPERATING M ANUAL 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. Setting the Scan-Resume Technique Two options for the Scan-Resume mode are available: TIME: In this mode, the scanner will halt on a signal it encounters, and will hold five seconds. If you do not take action to disable the scanner within five seconds, the scanner will resume even if the stations are still active. BUSY: In this mode, the scanner will halt on a signal it encounters. Two seconds after the carrier has dropped because the other station(s) ceased transmission, the scanner will resume. To set the Scan-Resume mode: 1. Press the [SET] key momentarily to enter the Set mode. 2. Rotate the “Main” band DIAL knob to select Menu #36 (SCAN). 3. Press the “Main” band DIAL knob momentarily, then rotate the “Main” DIAL knob to select the desired scan-resume mode. 4.

FCC ID: K66FT-8900R OPERATING M ANUAL clockwise). You’ll see the scanner turn around and change frequency downward! You may change the scanning operation so that the VFO frequency will jump to the low band edge of the next band when the VFO frequency reaches the high edge of the current band (or vice versa). See page xx regarding Menu #4 (BAND). Memory 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 [V/M] key, if necessary. 2. Using the techniques learned earlier, store (per the above concept) 144.300 MHz into Memory Channel #L1 (the “L” designates the Lower sub-band limit). 3. Likewise, store 148.000 MHz into Memory Channel #U1 (the “U” designates the Upper sub-band limit). 4. Switch to the Memory mode by pressing the [V/M] key once, then rotate the DIAL knob to select Memory Channel # L1. 5. Press and hold in the [V/M] key for 1/2 second to start PMS operation; the “MT” label will be appears on the display. Tuning and canning will now be limited within the just-programmed range. 6. Five pairs of Band Limit memories, labeled L1/U1 through L5/U5 are available. You therefore can set upper and lower operation limits on a number of bands, if you like. “Priority Channel” Channel” Scanning (Dual Watch) The FT-8900’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 (Menu #36: SCAN). See page xx. Here is the procedure for activating Priority Channel Dual Watch operation: 21 Vertex Standard Co., Ltd.

The “P” icon (for the “Main” band priority channel) or “p” icon (for the “Sub” band priority channel) will appear to the right of the “MR” icon, indicating it is the Priority channel. 4. Now set the VX-7 VX-7R for operation on another memory channel, or on a VFO frequency. 5. Press the [MON/F] key, then press the [2(DW)] key. The display will remain on the VFO or memory channel selected, but every four seconds the VX-7 VX-7R will check the Priority Channel for activity. Smart Search The Smart Search feature may be used to load - automatically with no operator intervention - a special bank of up to 25 memory channels (per band) on activity. The Smart Search will sweep the entire band, and will load the special memory bank with the frequency and repeater shift data pertaining to those channels on which activity is found (if Automatic Repeater Shift is activated). The channel are loaded in order in which they are encountered, not according to signal strength or by ascending frequency. The Smart Search feature is especially useful when visiting a city for the first time, where you may be unfamiliar with the repeater frequencies; Smart Search discovers where the local activity is to be found, and automatically loads those frequencies for you. Smart Search operation is simple to activate: 1. Set the radio to the VFO mode by pressing the [V/M] key, if necessary. 2. Press and hold the [V/M] key, cause the radio to scan upward on current band, loading channels on which it encounters a signal strong enough to open the squelch. 3.

Says: 1) The Smart Search memories are so-called “soft” memories; they will lost if you exit the Smart Search mode or initiate a new Smart Search sweep. 2) You may activate the Smart Search operation on the “Main” band by press and hold the microphone’s [P2] key. 3) You may activate the Smart Search operation on the “left” and “right” bands at the same time. ARTSTM: Auto Range Transpond 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. Whenever you push the PTT switch, or every 25 seconds after ARTS is activated, your radio will transmit a signal which includes a (subaudible) DCS signal for about 1 second. If the other radio is in range, the beeper will sound (if enabled) and the display will show “INRNG” as opposed to the out of range display “OUTRNG” in which ARTS operation begins. Whether you talk or not, the polling every 25 seconds will continue until you de-activate ARTS. Every 10 minutes, moreover, you can have your radio transmit your callsign via 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 sense that no signal has been received, three beeps will sound, and the display will revert to “OUTRNG.” If you move back into range, your radio will again beep, and the display 23 Vertex Standard Co., Ltd.

FCC ID: K66FT-8900R OPERATING M ANUAL will change back to the “INRNG” indication. During ARTS operation, it is not possible to change the operating frequency or other settings on the “Main” band; you must terminate ARTS in order to resume normal operation.

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®, 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). Occasionally, signal inversion can result in the complement of a code to be sent or received. This prevent receiver squelch from opening with DCS enabled, as the decoded bit sequence would not match that selected for operation. Typical situations that might cause inversion to occur are:  Connection of an external receiver preamplifier.  Operating through a repeater.  Connection of an external linear amplifier. Note that code inversion does not mean that any of the above listed equipment is detective ! In certain amplifier configurations, the output signal (phase) is inverted from the input. Small signal or power amplifiers having an odd number (1, 3, 5, etc.) of amplification stages may result in inversion of a transmitted or received DCS code. While under most circumstances this should not occur (amplifier designs and industry standards take this into account), if you find that your receiver squelch does not open when both you and the other station are using a common DCS code, you or the other station (but not both) can try the following: 1.
