8-7■Memo padsThe transceiver has a memo pad function to store fre-quency and operating mode for easy write and recall.The memo pads are separate from memory channels.The default number of memo pads is 5, however, thiscan be increased to 10 in set mode if desired. (p. 12-16)Memo pads are convenient when you want to memo-rize a frequency and operating mode temporarily, suchas when you find a DX station in a pile-up, or when adesired station is busy for a long time and you want totemporarily search for other stations.Use the transceiver’s memo pads instead of relying onhastily scribbled notes that are easily misplaced.DWriting frequencies and operating modes into memo padsYou can simply write the accessed readout frequencyand operating mode by pushing [MP-W].When you write a 6th frequency and operating mode,the oldest written frequency and operating mode areautomatically erased to make room for the new set-tings.Each memo pad must have its own unique combi-nation of frequency and operating mode; memopads having identical settings cannot be written.DCalling up a frequency from a memo padYou can simply call up the desired frequency and op-erating mode of a memo pad by pushing [MP-R] sev-eral times.• Both VFO and memory modes can be used.• The frequency and operating mode are called up, startingfrom the most recently written.When you call up a frequency and an operating modefrom memo pads with [MP-R], the previously displayedfrequency and operating mode are automaticallystored in a temporary pad. The frequency and operat-ing mode in the temporary pad can be recalled bypushing [MP-R] several times.• You may think there are 6 memo pads because 6 differentfrequencies (5 are in memo pads and 1 is in the temporarypad) are called up by [MP-R].If you change the frequency or operating modecalled up from a memo pad with the main dial, etc.,the frequency and operating mode in the temporarypad are erased.NewestMEMO PADSOldestNewestErasedOldestIn this example, 21.276 MHz (LSB) will be erased when 7.067 MHz (LSB) is written.[MP-R][MP-W]8MEMORY OPERATION

10-5■Antenna tuner operationThe internal automatic antenna tuner matches thetransceiver to the connected antenna automatically.Once the tuner matches an antenna, the variable ca-pacitor angles are memorized as a preset point foreach frequency range (100 kHz steps). Therefore,when you change the frequency range, the variable ca-pacitors are automatically preset to the memorizedpoint.CAUTION: NEVER transmit with the tuner ON whenno antenna is connected. This will damage thetransceiver. Be careful of the antenna selection.DTuner operation➥Push [TUNER] to turn the internal antenna tunerON. The antenna is tuned automatically when theantenna SWR is higher than 1.5:1.• When the tuner is ON, the “TUNE” indicator appears.• MANUAL TUNINGDuring SSB operation at low voice levels, the internaltuner may not be tuned correctly. In such cases, man-ual tuning is helpful.➥Push [TUNER] for 1 sec., to start manual tuning.• A side tone is emitted and “TUNE” indicator blinks whiletuning.• If the tuner cannot reduce the SWR to less than 1.5:1after 20 sec. of tuning, the [TUNER] switch indicatorgoes out.• AUTOMATIC TUNER START (HF bands only)If you want to deactivate the tuner under conditions ofVSWR 1.5:1 or less, use the auto tuner start functionand turn the tuner OFF. This function activates thetuner automatically when the SWR exceeds 1.5:1.This function is turned ON in set mode. (p. 12-14).NOTES:•NEVER transmit without an antenna properly con-nected to antenna port in use.• When 2 or more antennas are connected, selectthe antenna to be used with [ANT].• If the SWR is higher than about 1.5:1 when tuningabove 100 kHz on an antenna’s preset point, push[TUNER] for 1 sec. to start manual tuning.• The internal tuner may not be able to tune in AMmode. In such cases, push [TUNER] for 1 sec. tomanually tune.[TUNER]10ANTENNA TUNER OPERATION
10-6■Antenna tuner operation (continued)• PTT TUNER STARTThe tuner is always tuned when the PTT is pushedafter the frequency is changed (more than 1% fromlast-tuned frequency). This function removes the “pushand hold [TUNER]” operation and activates for the firsttransmission on a new frequency. This function is turned ON in set mode. (p. 12-14).• Antenna tuner of the IC-PW1When using an external antenna tuner such as the IC-PW1’s tuner, tune with the external antenna tuner,while the internal tuner is turned OFF. After tuning iscompleted, turn the internal tuner ON. Otherwise, bothtuners tune simultaneously and correct tuning may notbe obtained.See the instruction manual included with each antennatuner for their respective operations.DIf the tuner cannot tune the antennaCheck the following and try again:• the [ANT] connector selection.• the antenna connection and feedline.• the unaltered antenna SWR. (Less than 3:1 for HF bands; Lessthan 2.5:1 for 50 MHz band)• the transmit power. (8 W for HF bands; 15 W for 50 MHz band)• the power source voltage/capacity.If the tuner cannot reduce the SWR to less than 1.5:1after checking the above, perform the following:• repeat manual tuning several times.• tune with a 50 Ωdummy load and re-tune the antenna.• turn power OFF and ON.• adjust the antenna cable length.(This is effective for higher frequencies in some cases.)• Some antennas, especially for low bands, have a narrowbandwidth. These antennas may not be tuned at the edgeof their bandwidth, therefore, tune such an antenna as fol-lows:[Example]: Suppose you have an antenna which has anSWR of 1.5:1 at 3.55 MHz and an SWR of 3:1at 3.8 MHz.qPush [TUNER] to turn the antenna tuner ON.wSelect CW mode.eTurn OFF the break-in function.
