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 follow- ing procedure. Resetting CLEARS all programmed contents in memory channels and returns programmed values in set mode to default values.
BASIC OPERATIONS ■ Main/Sub band selection The IC-7800 has 2 identical receivers, main and sub. The main band is displayed on the left hand side, and the sub band is displayed on the right hand side of the LCD. Some functions can only be applied to the selected band and transmission occurs on the main band (except during split frequency operation).
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. If a band key is pushed once, the frequency and op- erating mode last used are called up. When the key is pushed again, another stored frequency and operating mode are called up.
BASIC OPERATIONS ■ Frequency setting The transceiver has several tuning methods for conve- nient frequency tuning. D Tuning with the main dial q Push the desired band key on the keypad 1–3 Band keys times. • 3 different frequencies can be selected on each band with the band key.

D Using the VOX function [VOX/BK-IN] q Select a phone mode (SSB, AM, FM). w Push [VOX/BK-IN] to turn the VOX function ON or OFF.
■ Break-in function The break-in function is used in CW mode to auto- matically toggle the transceiver between transmit and receive when keying. The IC-7800 is capable for full break-in or semi break-in. D Semi break-in operation During semi break-in operation, the transceiver selects transmit when keying, then automatically returns to re- ceive after a pre-set time after you stop keying.
FUNCTIONS FOR TRANSMIT ■ ∂TX function The ∂TX function shifts the transmit frequency up to ±9.999 kHz in 1 Hz steps (10 Hz steps when cancel- ling the 1 Hz step readout) without moving the receive frequency. • See (3 on p. 1-11 for function description. q Push [∂TX].
FUNCTIONS FOR TRANSMIT ■ Transmit filter width setting (SSB only) The transmit filter width for SSB mode can be selected from wide, middle and narrow. ➥ During USB or LSB mode selection, push [COMP] [COMP] for 1 sec. several times to select the desired trans- mit filter width from wide, middle and narrow.
FUNCTIONS FOR TRANSMIT ■ Split frequency operation Split frequency operation allows you to transmit and receive in the same mode on two different frequen- cies. The 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 consider- ation is how to set the split frequency. When you push the [SPLIT] switch for 1 sec., split fre- quency operation is turned ON, the sub readout is equalized to the main readout frequency and enters standby for transmit frequency input.

MEMORY OPERATION ■ Memory list screen The memory list screen simultaneously shows 9 mem- ory channels and their programmed contents. 15 memory channels can be displayed in the wide mem- ory list screen. You can select a desired memory channel from mem- ory list screen.
MEMORY OPERATION ■ Memory channel programming Memory channel programming can be preformed ei- ther in VFO mode or in memory mode. D Programming in VFO mode q Set the desired frequency, operating mode and filter width in VFO mode. w Push [Y]/[Z] several times to select the desired memory channel.
MEMORY OPERATION ■ Frequency transferring The frequency and operating mode in a memory chan- nel can be transferred to the VFO. Frequency transferring can be performed in either VFO mode or memory mode. D Transferring in VFO mode This is useful for transferring programmed contents to TRANSFERRING EXAMPLE IN VFO MODE Operating frequency : 21.320 MHz/USB (VFO) VFO.
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 chan- nels. 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 operate a scan while operating on a fre- quency using the dualwatch or 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 receiver checks received signals for voice components. If a receiver signal includes voice components, and the tone of the voice components changes within 1 sec., scan pauses (or stops).
SCANS ■ Programmed scan operation q Push [EXIT/SET] several times to close a multi-func- tion screen, if necessary. w Select VFO mode. e Select the desired operating mode. • The operating mode can also be changed while scan- ning. r Push [F-5•SCAN] to select the scan screen. t Set the main band’s [SQL] open or closed.
Page 135
SCANS ■ Fine programmed scan/fine ∂F scan In fine scan (programmed or ∂F), the scan speed de- creases when the squelch opens, but the transceiver keeps scanning. The scanning tuning step shifts from 50 Hz to 10 Hz when the squelch opens. q Push [EXIT/SET] several times to close a multi-func- tion screen, if necessary.
SCANS ■ Memory scan operation q Push [EXIT/SET] several times to close a multi-func- tion screen, if necessary. w Select memory mode. e Push [F-5•SCAN] to select the scan screen. r Set the main band’s [SQL] open or closed. • See page 9-2 for squelch condition. t Push [F-1•MEMO] to start the memory scan.

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 angles 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 point.
When using an external antenna tuner such as the IC-PW1’s tuner, tune with the external antenna tuner, and turn OFF the IC-7800’s tuner. After tuning is com- pleted, turn the internal tuner ON. Otherwise, both tun- ers tune simultaneously and correct tuning may not be obtained.
