N Split frequency operationSplit frequency operation allows you to transmit and receive in the same mode on two different frequen-cies. Split frequency operation is performed using 2 frequencies on the main and sub readouts.The following is an example of setting 21.290 MHz for receiving and 21.310 MHz for transmitting.q Set 21.290 MHz (USB) in VFO mode.w Push [SPLIT] momentarily, then push and hold [CHANGE] for 1 sec. • The quick split function is much more convenient for selecting the transmit frequency. See the next section for details. • The equalized transmit frequency and “ ” appear on the LCD. • [SPLIT] indicator lights. • “ ” appears to show the transmit frequency read-out.e Rotate the main dial while pushing [XFC] to set the transmit frequency to 21.310 MHz. • The transmit frequency can be monitored while push-ing [XFC].r Now you can receive on 21.290 MHz and transmit on 21.310 MHz.To change the transmit and receive frequencies, push [CHANGE] to exchange the main and sub readouts. CONVENIENT• Direct shift frequency inputThe shift frequency can be entered directly.q Push [F-INP ENT].w Enter the desired shift frequency with the digit keys. • 1 kHz to 1 MHz can be set. • When you require a negative shift direction, push in advance.e Push [SPLIT] to input the shift frequency in the sub readout and the split function is turned ON.• Dualwatch functionThe dualwatch function is convenient for tuning the transmit frequency while monitoring both frequencies used for transmitting and receiving.• Split lock function (p. ??)Accidentally releasing [XFC] while rotating the main dial changes the receive frequency. To prevent this, use both the split lock and dial lock functions to change the transmit frequency only. The split lock function cancels the dial lock function while pushing [XFC] during split frequency operation.The dial lock’s effect during split frequency operation can be selected in the set mode for both receive and transmit frequencies; or only the receive frequency.

N Quick split functionWhen you find a DX station, an important consider-ation is how to set the split frequency.When you push and hold the [SPLIT] switch for 1 sec., the split frequency operation is turned ON, and the sub readout frequency is equalized to the main readout frequency, then enters standby for transmit frequency input.This shortens the time needed to begin split fre-quency operation.The quick split function is ON by default. For your convenience, it can be turned OFF in others set mode. (p. ??) In this case, the [SPLIT] switch does not equalize the main and sub readout frequencies.q Suppose you are operating at 21.290 MHz (USB) in VFO mode. w Push and hold [SPLIT] for 1 sec. • Split frequency operation is turned ON. • The sub readout is equalized to the main readout fre-quency. • The sub readout enters standby for transmit frequency input and “ ” appears. • During FM mode operation, the sub readout frequency shifts from the main readout frequency according to the others set mode setting.e Rotate the main dial to set the transmit frequency; or, input the transmit frequency using the keypad and [F-INP ENT]; or, input a shift frequency using the keypad and [SPLIT]. • “ ” disappears when [F-INP ENT] is pushed. • Offset frequency setting with the keypad and [SPLIT]. [Example] To transmit on 1 kHz higher frequency: - Push [1.8 1] then [SPLIT]. To transmit on 3 kHz lower frequency: - Push [GENE •], [7 3] then [SPLIT].D Split lock functionThe split lock function is convenient for changing only the transmit frequency. When the split lock function is not used, accidentally releasing [XFC] while rotat-ing the main dial, changes the receive frequency. The split lock function is ON by default, but can be turned OFF in set mode. (p. ??)q While split frequency operation is ON, push and hold [SPEECH/LOCK] for 1 sec. to activate the split lock function. • [LOCK] indicator lights.w While pushing and holding [XFC], rotate the main dial to change the transmit frequency. • If you accidentally release [XFC] while rotating the main dial, the receive frequency does NOT change.Main dial[SPLIT] indicator KeypadXFCSPLITMain dial[LOCK] indicatorSPEECHLOCKXFC894RECEIVE AND TRANSMIT

N Memo padsThe transceiver has a memo pad function to store fre-quency and operating mode for easy writing and re-calling. The memo pads are separate from memory channels.The default number of memo pads is 5, however, this can be increased to 10 in set mode if desired. (p. ??)Memo pads are convenient when you want to mem-orize a frequency and operating mode temporarily, such as when you find a DX station in a pile-up, or when a desired station is busy for a long time and you want to temporarily search for other stations.Use the transceiver’s memo pads instead of relying on hastily scribbled notes that are easily misplaced.MP-RMP-WD Writing frequencies and operating modes into memo padsYou can store the readout frequency and operating mode by pushing [MP-W].When you store the 6th frequency and operating mode, the oldest stored frequency and operating mode are automatically erased to make room for the new settings. Each memo pad must have its own unique combi-nation of frequency and operating mode; memo pads having identical settings cannot be written.MP-WNewestErasedOldestIn this example, 21.276 MHz (USB) will be erasedwhen 7.067 MHz (LSB) is written.D Calling up a frequency from a memo padYou can call up the desired frequency and operat-ing mode of a memo pad by pushing [MP-R] several times.• Both VFO and memory modes can be used.• The frequency and operating mode are called up, starting from the most recently written.When you call up a frequency and an operating mode from memo pads with [MP-R], the previously dis-played frequency and operating mode are automat-ically stored in a temporary pad. The frequency and operating mode in the temporary pad can be recalled by pushing [MP-R] several times.• You may think there are 6 memo pads because 6 different frequencies (5 are in memo pads and 1 is in the tempo-rary pad) are called up by [MP-R]. If you change the frequency or operating mode called up from a memo pad with the main dial, etc., the frequency and operating mode in the tempo-rary pad are erased.MP-RNewestOldestMEMO PADSMP-R1046MEMORY OPERATION123456789101112131415161718192021

N Automatic antenna selectionThe transceiver covers 0.03–60 MHz over 10 bands. Each band key has a band memory which can mem-orize a selected antenna (ANT1, ANT2, ANT1/RX an-tenna and ANT2/RX antenna). When you change the operating frequency beyond a band, the previously used antenna is automatically selected. This function is convenient when you use 2 or 3 antennas.To use the band memory, enter set mode and con-firm that “Auto” is selected as the [ANT] switch item. (p. ??)• Antenna selection mode: “Auto” (default)The antenna tuner ON/OFF condition is also memo-rized in the band memory.[Example]: a 3.5/7 MHz antenna is connected to [ANT1], a 21/28/50 MHz antenna is connected to [ANT2]. When the antenna selector function is set to “Auto,” an antenna is automatically selected when the transceiver changes bands.• Antenna selection mode: “Manual”[ANT] (MF1) functions, however, band memory does not function. In this case, you must select an antenna manually.Under the following conditions, “Manual” should be selected as the [ANT] switch set mode item.- When using 1 antenna.- When using an external antenna selector for more than 3 antennas (except for receive antenna).- When using an external antenna tuner.NOTE: When “Auto” or “Manual” is selected, the antenna tuner ON/OFF condition is consistent with [ANT] (MF1).• Antenna selection mode: “OFF”[ANT] (MF1) does not function and [ANT1] is always selected.3.5/7 MHzbands21/28/50 MHzbandsRXonlyANT1 ANT2RX ANTINANT8112ANTENNA TUNER OPERATION123456789101112131415161718192021

■ Optional external tuner operation• AH-4 HF AUTOMATIC ANTENNA TUNERThe AH-4 matches the IC-7600 to a long wire an-tenna more than 7 m/23 ft long (3.5 MHz and above).• See p. ?? for the transceiver and AH-4 connection.• See the AH-4 instruction manual for AH-4 installa-tion and antenna connection details.AH-4 setting example:For mobile operation For outdoor operation Long wireOptional AH-2bantenna elementR DANGER: HIGH VOLTAGE! NEVER touch the antenna element while tuning or transmitting.NEVER operate the AH-4 without an antenna wire. The tuner and transceiver will be damaged.NEVER operate the AH-4 when it is not grounded.Transmitting before tuning may damage the trans-ceiver. Note that the AH-4 cannot tune when using a ½λ long wire or multiple of the operating frequency. When connecting the AH-4, the antenna connec-tor assignments are [ANT2] for the internal tuner and [ANT1] for the AH-4. The antenna indicator in the LCD displays “ANT1(EXT)” when the AH-4 is connected and selected.• AH-4 operationTuning is required for each frequency. Be sure to re-tune the antenna before transmitting when you change the frequency— even slightly.q Set the desired frequency in an HF or 50 MHz band for use with the AH-4. • The AH-4 will not operate on frequencies outside of ham bands.w Push [TUNER] for 1 sec. • The indicator on the switch blinks while tuning.TUNERe The indicator on the switch lights constantly when tuning is complete. • When the connected wire cannot be tuned, the indicator on the switch goes out and the AH-4 is bypassed. At that point the antenna wire connec-tion is to the transceiver directly, and not via the AH-4 antenna tuner.r To bypass the AH-4 manually, push [TUNER].M If the tuner cannot tune the antennaCheck the following and try again:• the [ANT] connector selection.• the antenna connection and feedline.• the untuned antenna SWR. (Less than 3:1 for HF bands; Less than 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 1.5:1 after checking the above, perform the following:• repeat manual tuning several times.• tune with a 50 Ω dummy load and re-tune the an-tenna.• turn power OFF and ON.• adjust the antenna feedline length. (This is effective for higher frequencies in some cases.)M Tuning a narrow bandwidth antennaSome antennas, especially for the low bands, have a narrow bandwidth. These antennas may not be tuned beyond the edge of their operating bandwidth, there-fore, tune such an antenna as follows:[Example]: Suppose you have an antenna which has an SWR of 1.5:1 at 3.55 MHz and an SWR of 3:1 at 3.8 MHz.q Push [TUNER] to turn the antenna tuner ON.w Select CW mode.e Turn OFF the break-in function.
