BASIC OPERATIONS ■ When first applying power (CPU resetting) Before first applying power, make sure all connections required for your system are complete by referring to Section 2. Then, reset the transceiver using the fol- lowing procedure. Resetting CLEARS all programmed contents in memory channels and returns programmed values in set mode to default values.
BASIC OPERATIONS ■ Selecting VFO/memory mode ➥ Push to switch between VFO and memory modes. • “ ” or “ ” appears when in VFO mode, or the VFO-A VFO-B selected memory channel number appears when in memory mode. • Holding down for 1 second transfers the con- tents of the selected memory channel to VFO.
BASIC OPERATIONS ■ Selecting an operating band The triple band stacking register provides 3 memories Band keys for each band key, storing frequency and mode infor- mation. This function is convenient when you operate 3 modes on one band. For example, one register is used for a CW frequency, another for an SSB fre- quency and the other one for an RTTY frequency.
BASIC OPERATIONS ■ Frequency setting The transceiver has several tuning methods for con- venient frequency tuning. D Tuning with the main dial q Push the desired band key on the keypad 1–3 Band keys times. • Three different frequencies can be selected on each band with the band key.

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.
FUNCTIONS FOR TRANSMIT ■ Quick split function When you find a DX station, an important considera- tion is how to set the split frequency. When you hold down the switch for 1 second, SPLIT split frequency operation is turned ON and the trans- mit frequency is equalized to the received frequency.

D Transferring in VFO mode This is useful for transferring programmed contents to TRANSFER EXAMPLE IN VFO MODE Operating frequency : 21.320 MHz/USB (VFO) a VFO.
MEMORY OPERATION ■ Memory list screen The memory list screen simultaneously shows 9 memory channels and their programmed contents. 15 memory channels can be displayed in the wide memory list screen. You can select a desired memory channel from the memory list screen.
MEMORY OPERATION ■ Memory names All memory channels (including scan edges) can be tagged with alphanumeric names of up to 10 charac- ters each. Capital letters, small letters, numerals, some symbols (! # $ % & ¥ ? " ’ ` ^ + – ✱ / . , : ; = < > ( ) [ ] { } | _ and spaces can be used.
MEMORY OPERATION ■ Memo pads The 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, this can be increased to 10 in set mode if desired.
SCANS ■ Scan types • The scan function can be used on the main read- out only. • You can perform a scan while operating on a fre- quency using the split functions. PROGRAMMED SCAN ∂F SCAN Repeatedly scans between two scan edge frequencies Repeatedly scans within ∂F span area.
SCANS ■ Voice squelch control function This function is useful when you don’t want unmodu- lated signals pausing or cancelling a scan. When the voice squelch control function is activated, the trans- ceiver checks received signals for voice components. If a received signal includes voice components, and the tone of the voice components changes within 1 second, scan pauses (or stops).

By monitoring a signal that is being transmitted on a repeater input frequency, you can determine the tone frequency required to access the repeater. q Set the desired frequency or memory channel to T-SCAN be checked for a tone frequency.
ANTENNA TUNER OPERATION ■ Antenna connection and selection The IC-7700 has 4 antenna connectors for the HF/50 MHz bands, [ANT1], [ANT2], [ANT3], and [ANT4]. For each operating band the IC-7700 covers, there is a band memory which memorizes the selected antenna.
ANTENNA TUNER OPERATION ■ Antenna memory settings This function stores the antenna connector number for each frequency band. q Push several times to close multi-function EXIT/SET Band keys screen, if necessary. w Hold down [ANT] for 1 second to select an- (MF1) tenna set screen.
ANTENNA TUNER OPERATION ■ Antenna memory settings (continued) D Temporary memory The antenna temporary memory memorizes the man- ually selected antenna. The selected antenna will be re-called even if frequency band has been changed. q Select the antenna set screen. w Push [TEMP-M] to turn the temporary mem- ory ON or OFF.
ANTENNA TUNER OPERATION D Receive antenna I/O setting In the default setting, receive antenna connectors, [RX ANT-IN] and [RX ANT-OUT], on the rear panel are deactivated and are connected internally by the switching relay. If you want to connect an external preamp or low-pass filter between the [RX ANT-IN] and [RX ANT-OUT], you must activate them as de- scribed below.
ANTENNA TUNER OPERATION ■ Antenna tuner operation The internal automatic antenna tuner matches the transceiver to the connected antenna automatically. After the tuner matches an antenna, the variable ca- pacitor settings are memorized as a preset point for each frequency range (100 kHz steps). Therefore, when you change the frequency range, the variable capacitors are automatically preset to the memorized setting.
When using an external antenna tuner such as the IC-PW1’s tuner, tune with the external antenna tuner, and turn OFF the IC-7700’s tuner. After tuning is com- pleted, turn the internal tuner ON. Otherwise, both tuners tune simultaneously and correct tuning may not be obtained.
