41FT-818 Operating ManualTransmitter OperationtiMe-Out tiMerMost often used on FM, the transmitter’s Time-Out Timer (TOT) feature disables the transmitter after a user-dened period of transmission. This feature may be useful in pre-venting a “stuck microphone” (accidental closure of the PTT switch) from causing inter-ference to other users, and it will also force you to keep your transmission short, thereby conserving battery power.To activate the Time-Out Timer:1. Press and hold in the key for one second to enter the Menu mode.2. Rotate the knob to recall Menu #49 (TOT TIME).3. The default setting for this feature is “off.” Rotate the knob to set a new time-out setting (from 1 minute to 20 minutes).4. When you have made your selection, press and hold in the key for one second to save the new setting and exit to normal operation.weatherFax MOnitOringMonitoring of HF WeatherFax broadcasts is easily accomplished using the FT-818.1. Before proceeding, be certain that the WeatherFax demodulator is properly connected to Pins 5 (DATA OUT 1200bps) and 2 (GND) of the rear panel DATA jack.2. Set the transceiver to the VFO mode, and set the operating mode to “DIG,” setting Menu #26 to PSK31-U, as described previously.3. Now, select the operating frequency of the station transmitting the WeatherFax broad-cast. Note that, in the USB mode, the frequency you should program onto the display is typically 1.90 kHz below the station’s “assigned” frequency. Thus for a WeatherFax station assigned to 8.682.0 MHz, tune to 8.680.1 MHz.4. When the WeatherFax broadcast begins, no further operator intervention should be needed from the transceiver standpoint. The audio level from the DATA jack on the rear of the transceiver is xed, and cannot be adjusted.Fine adjustments in the gray-scale and the frame alignment are accomplished using the computer and software connected to your WeatherFax demodulator.

When this is done, the “MTQMB” will appear in the display, where “MT” represents “Memory Tuning.” Press the (RCL) key once more to return to the originally-stored QMB frequency.Memory Operation
43FT-818 Operating ManualMemory OperationMeMOrY OperatiOn On “regular” MeMOrY channelSNormal Memory Storage1. Tune in the desired frequency, and set the operating mode and bandwidth. If this is an FM channel, set up any required CTCSS/DCS and repeater shift congurations. Stan-dard (default) repeater shifts do not require you to utilize the “split” frequency memo-ry technique, described later.2. Press the key momentarily, then rotate the knob, as needed, until Operating Function Row 2 [MW, MC, TAG] appears on the display.3. Press the (MW) key momentarily to enter the “Memory Check” mode, which is used to nd an unused memory channel. The frequency stored (if any) on the current memory channel will be shown in the display.4. Rotate the knob to select the channel number on which you wish to store the current frequency data.5. Press and hold in the (MW) key for one second until you hear a double beep; the second beep conrms that the frequency information was successfully stored.Split-Frequency Memory StorageYou can also store “Split” frequencies, such as when operating on a repeater system not uti-lizing a “standard” offset. This procedure may also be used for DX work on 7 MHz SSB, etc. 1. In the VFO mode, set the desired Receive frequency and mode.2. Press the key momentarily, then rotate the knob, as needed, until Operating Function Row 2 [MW, MC, TAG] appears on the display.3. Press the (MW) key momentarily to enter the “Memory Check” mode, which is used to nd an unused memory channel. The frequency stored (if any) on the current memory channel will be shown in the display.4. Rotate the knob to select the channel on which you wish to store the receive fre-quency data.5. Press and hold in the (MW) key for one second until you hear a double beep, which conrms that the Receive frequency data is now stored.6. Now, set the desired Transmit frequency and mode on the VFO.7. Press the (MW) key momentarily; do not rotate the knob!8. While the “memory channel number” is blinking, press and hold in the PTT switch; while holding it in, press and hold in the (MW) key for one second. The double “beep” will conrm that independent Transmit frequency data is now stored. You may now release the PTT switch.In step 8 above, pressing the PTT switch does not activate the transmitter. It simply sends a signal to the microprocessor that an independent Transmit frequency is being stored on the same channel as a previously-stored Receive frequency.
44 FT-818 Operating ManualMemory OperationMemory Channel Recall1. If you currently are in the VFO tuning mode, press the key once to enter the “Memory” mode (a memory channel number “M-nnn” will appear on the display in she space previously occupied by “VFOa” or “VFOb”).2. To select another memory channel, turn the knob.3. When your memory channels are partitioned into Memory Groups via Menu #34, it is easy to change Memory Groups; press the knob momentarily (a Group Number (“a” ~ “j”) will blink), then turn the knob to step through the channels until you enter another. You may now press the knob once more to restrict memory channel access to the newly-selected Group.4. Once you are operating on a memory channel, you may tune off of the original-ly-memorized frequency (as though you were in the VFO mode). Just rotate the knob; the “Memory Channel Number” will be replaced by one which indicates “MTUNE,” indicating that you have now shifted into the “Memory Tuning” mode. When operating the Memory Tuning mode, if you nd another frequency you wish to store into another memory channel, just press the (MW) key momentarily, select a new memory channel via the knob, then press and hold in the (MW) key until you hear the double beep.5. To exit the Memory Tuning mode, press the key as follows: One touch of the key returns you to the original memory frequency. A second touch of the key will cause you to exit the Memory mode and return to the VFO mode (the memory channel number will be replaced by “VFOa” or “VFOb”).When operating on a “Split” frequency memory, a special “ ” indication will appear on the LCD.Memory Group “OFF”Memory Group “ON”
45FT-818 Operating ManualMemory OperationMasking MemoryFrequency data stored on a memory channel can be deleted, if desired, from any memory channel except channel “1.” The deletion process is not a “hard” erasure, so if you erase a channel by mistake using this procedure, the memory channel contents can be recovered.1. Press the key momentarily, then rotate the knob, as needed, until Operating Function Row 2 [MW, MC, TAG] appears on the display.2. Press the (MW) key momentarily, then rotate the knob to select the memo-ry channel to be deleted.3. Press the (MC) key momentarily. The frequency display eld on the LCD will go blank, and the memory channel number will blink.4. Wait about three seconds; when the memory channel number stops blinking, the data will now be “masked” and will not be available for operation.5. To restore the masked frequency data, repeat the above steps. However, if you store new frequency information on a channel containing masked data, the masked data will be over-written and lost.6. Memory Channel 1 is used for Priority operation, and frequency information may only be over-written (not masked) on this channel.
46 FT-818 Operating ManualMemory OperationMeMOrY OperatiOn On “hOMe” channel MeMOrieSFour Special one-touch “Home” channels are available, for special frequencies you use often. Either “simplex” or “split” frequency/mode data may be stored in the “Home” channel locations. Special “Home” channels are available for HF (any frequency between 1.8 and 29.7 MHz), 50 MHz, 144 MHz, and 430 MHz.These memories may prove particularly useful for monitoring propagation beacons, pro-viding one-touch recall of the beacon frequency for a quick check of band conditions.HOME Channel Storage1. Tune the desired frequency, and set the operating mode. If this is an FM channel, set up any required CTCSS/DCS and repeater shift congurations.2. Press the key momentarily, then rotate the knob, as needed, until Operating Function Row 2 [MW, MC, TAG] appears on the display.3. Press the (MW) key momentarily to enter the “Memory Check” mode.4. Press and hold in the key for one second. This stores the frequency data into the “Home” channel location. As usual, you will hear a double beep to conrm the suc-cessful storage of the frequency data.5. If you wish to store a “Split” frequency pair into the “Home” channel, store the Re-ceive frequency in steps 1 ~ 4 above. Now set the desired Transmit frequency.6. Once more, press the (MW) key momentarily.7. Press and hold in the microphone’s PTT switch; while holding the PTT switch, again press and hold the key for one second. This stores the transmit frequency data into the “Home” channel location.HOME Channel Recall1.

49FT-818 Operating ManualNote: This operation does not function in the FM Broadcast frequencies.The Smart SearchTM feature automatically stores frequencies where activity is encoun-tered on the current band. When Smart SearchTM is engaged, the transceiver quickly searches above your current frequency, storing active frequencies as it goes (without stopping on them even momentarily). These frequencies are stored in a special Smart SearchTM memory bank, consisting of 50 memories. This feature available on the FM and AM modes. The Smart Search™ feature is especially helpful when traveling, as you can instantly store active FM repeater frequencies without having to look up the frequencies in a refer-ence book.1. Set the knob to the point where background noise is silenced. A typical set-ting, for effective Smart SearchTM operation, will be at 12 o’clock or slightly clock-wise from this position.2. Set the VFO to the frequency on which you wish to begin the search (the Smart SearchTM feature is available on the VFO mode only).3. Press the key momentarily, then rotate the knob, as needed, until Operating Function Row 6 [SSM, SCH, ART] appears on the display.4. Now press the (SCH) key momentarily; the blinking “SRCH” indicator will ap-pear on the LCD, and the transceiver will sweep upward on the current band, loading channels on which it encounters a signal strong enough to open the squelch.5. All channels where activity is present (up to 50 channels) will be loaded into the Smart SearchTM memories. Whether or not all 50 memories are lled, the search will stop after one sweep.6. Now you can turn the knob to select from the just-stored Smart SearchTM mem-ories. If you nd frequencies you wish to store into a “regular” memory, just follow the procedures described previously; just don’t press the (SCH) key while storing these memories, because this will disable Smart Search™ operation (see step 7).7. To disable Smart SearchTM operation, press the (SCH) key momentarily.The Smart Search™ memories are so-called “soft” memories; they will be lost if you initiate a new Smart SearchTM sweep of the band.Smart Search™ Operation
50 FT-818 Operating ManualNote: This operation does not function in the FM Broadcast frequencies.This transceiver contains a wide variety of scanning capabilities. Whether you are in the VFO mode or one of the memory modes, scanning operation is fundamentally identical in all congurations, but with the following differences: In the VFO mode, scanning causes the transceiver to sweep up or down the band, pausing or halting on any signal encountered; In the Memory mode, the scanner will scan the programmed memories, and can be instructed to skip certain memories during scanning; In the Programmable Memory Scan (PMS) mode, the scanner will scan the band within user-programmed frequency limits.Scanning Operation1. Set the knob to the point where background noise is silenced. A typical set-ting, for effective scanning operation, will be at 12 o’clock or slightly clockwise from this position.2. Set the transceiver into the operating conguration in which you wish to scan (VFO or Memory; PMS will be described later).8. Press the key momentarily, then rotate the knob, as needed, until Operating Function Row [SCN, PRI, DW].3. Press the (SCN) key momentarily to start upward scan (toward higher frequen-cies or higher memory channel numbers).4. Rotate the knob or knob counterclockwise to toggle the scanning direc-tion downward.5. The scanner will now cause the transceiver to increment in the chosen direction until a signal is detected. When a signal is encountered which opens the Squelch, In the FM/AM modes, the scanner will pause until the signal disappears (at the end of the other station’s transmission), at which point scanning will resume. While the transceiv-er is in the “Pause” condition, the decimal points in the frequency display area will blink. See “Scan-Resume Choices” on the next page for details of how to customize the resumption of scanning, In the SSB/CW modes, the scanner will slow down (but doesn’t stop).6. Press the PTT switch on the microphone to cancel scanning.You may also press and hold in either the [UP] or [DWN] key on the microphone for 1/2 second to initiate upward or downward scanning, respectively, if Menu #37 (MIC SCAN) is set to “ON”.Scanning Operation
