3 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 following procedure. Resetting CLEARS all programmed contents in memory channels and returns programmed values in set mode to default values. q Turn the main power ON with [I/O] on the rear panel. [I/O] • The transceiver power is still OFF and the [POWER] indicator lights orange.
BASIC OPERATIONS 3 ■ 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). ➥ Push [MAIN] to select the main band. [MAIN] [SUB] • The key backlight for [MAIN] lights. • Main band’s frequency readout highlighted.
3 BASIC OPERATIONS ■ Selecting an operating band The triple band stacking register provides 3 memories for each band key, storing frequency and mode information. Band keys If a band key is pushed once, the frequency and operating mode last used are called up. When the key is pushed again, another stored frequency and operating mode are called up. This function is convenient when you operate 3 modes on one band.
BASIC OPERATIONS 3 ■ Frequency setting The transceiver has several tuning methods for convenient frequency tuning. D Tuning with the main dial q Push the desired band key on the keypad 1–3 times. Band keys • 3 different frequencies can be selected on each band with the band key. • Push [MAIN] or [SUB] to select the band. w Rotate the main dial to set the desired frequency in the main band, rotate the sub dial to set the desired frequency in the sub band.
3 BASIC OPERATIONS D Quick tuning step The operating frequency can be changed in kHz steps (0.1, 1, 5, 9, 10, 12.5, 20 or 25 kHz selectable) for quick tuning. q Push [TS] to turn the quick tuning function ON. • “Z” appears when the quick tuning function ON. w Rotate the main dial to change the frequency in programmed kHz steps. e Push [TS] again to turn OFF the indicator. r Rotate the main dial for normal tuning if desired.
BASIC OPERATIONS 3 D Selecting 1 Hz step The minimum tuning step of 1 Hz can be used for fine tuning. q Push [TS] to turn the quick tuning function OFF. w Push [TS] for 1 sec. to turn the 1 Hz tuning step ON and OFF. NOTE: 1 Hz tuning step activates for both main and sub bands simultaneously. Therefore, either [TS] can be used for the 1 Hz tuning step selection.
3 BASIC OPERATIONS ■ Operating mode selection SSB (USB/LSB), SSB data (USB data/LSB data), CW, CW reverse (CW-R), RTTY, RTTY reverse (RTTY-R), PSK, PSK reverse (PSK-R), AM, AM data, FM and FM data modes are available in the IC-7800. Select the desired operation mode as follows. To select a mode of operation, push the desired mode switch momentarily. Push the switch again to toggle between USB and LSB, CW and CW-R, RTTY/RTTYR and PSK/PSK-R, AM and FM, if desired. Push the switch for 1 sec.
BASIC OPERATIONS ■ Volume setting 3 ➥ Rotate [AF] control clockwise to increase, counterclockwise to decrease the audio output level. • Set a suitable audio level. [AF] for main [AF] for sub Audio output increases Audio output decreases ■ RF gain adjustment [RF] for main ➥ Rotate [RF] control clockwise to increase, counterclockwise to decrease the receiver sensitivity.
3 BASIC OPERATIONS ■ Meter indication selection The S/RF meter indication, during transmit, can be selected from the following items as you desire. ➥ Push [METER] several times to select the desired item. Indicates the RF output power in watts. [METER] Indicates the VSWR on the transmission line. Signal strength level readout 9 5 +20 +40 1 5 S 0 10 50 100 150 200 ID ID readout 0 10 3 PO 1.

3 BASIC OPERATIONS ■ Basic transmit operation Before transmitting, monitor your selected operating frequency to make sure transmitting won’t cause interference to other stations on the same frequency. It’s good amateur practice to listen first, and then, even if nothing is heard, ask “is the frequency in use” once or twice, before you being operating on that frequency.
BASIC OPERATIONS 3 D Drive gain adjustment The drive gain is active for all modes except SSB without speech compressor. The [DRIVE] control adjusts the amplifying gain at the driver stage. Before transmitting, monitor your selected operating frequency to make sure transmitting won’t cause interference to other stations on the same frequency. [METER] [DRIVE] q Push [METER] to select the ALC meter.

16 UPDATING THE FIRMWARE ■ General The IC-7800’s firmware can be updated if desired. By updating the firmware, new function(s) can be added and the improvement of performance parameters can be made. 2 ways of firmware update are available; one is using the CF memory card, and the other is using a PC. You can choose either way according to your PC condition. A memory card reader is required to copy the downloaded firmware file.
UPDATING THE FIRMWARE 16 ■ Preparation D Firmware and firm utility The latest firmware and the firm utility can be downloaded from the Icom home page via the internet. Access the following URL to download the firm utility and the latest firmware. http://www.icom.co.jp/world/download/index.htm For updating from the CF memory card When updating the firmware from the CF memory card, copy the downloaded firmware data (e.g. 7800_110.
16 UPDATING THE FIRMWARE ■ Firmware update— CF memory card When updating the firmware using with the CF memory card, no IP address as well as subnet mask settings are necessary. [F-3•FIRM UP]/[F-3•Z] q Copy the downloaded firmware data into the CF memory card (“IC-7800” folder). [F-7•SET]/[F-7•CF CARD] /[F-7•CANCEL] • The CF memory card must be formatted by the IC-7800. w Insert the CF memory card into the CF card slot. e Push [EXIT/SET] several times to close a multifunction screen, if necessary.
UPDATING THE FIRMWARE 16 !3 After the firmware loading is completed, the transceiver starts the update automatically and the dialog as at left is displayed. RWARNING!: NEVER turn the IC-7800 power OFF at this stage. The transceiver firmware will be damaged. !4 When the dialog disappears, the precaution as at left is displayed. !5 Read the precaution carefully, and then push [F-6•OK]. • Return to CF card set menu. !6 Push [POWER] to turn the IC-7800 power OFF, then ON again.
16 UPDATING THE FIRMWARE ■ Firmware update— PC D Connections Connect the IC-7800 and the PC through a LAN (Local Area Network) as follows. PC1 (192.168.100.11) PC2 (192.168.100.12) IC-7800 (192.168.100.13) Hub/Router* Ethernet cable* (Patch cable) to crossover port = × × × × to WAN /Internet network *Purchased separately • IP address setting example PC1 IP address PC2 IC-7800 192.168.100.11 192.168.100.12 192.168.100.13 Subnet mask 255.255.255.0 255.255.255.0 16-6 255.255.255.
UPDATING THE FIRMWARE D IP address setting 16 When updating the firmware from the CF memory card, the following settings are not necessary. IMPORTANT!: A fixed (static) IP address is used for the IC-7800. When you connect the IC-7800 to a LAN, ask the network manager about a usable/assignable IP address and the subnet mask in advance. NEVER set the IP address that has already been used with another device in the network. If the IP address is duplicated, the network will crash down.
16 UPDATING THE FIRMWARE D Updating from the PC q Start up the IC-7800 Firm Utility. • The window as at left appears. w Read the caution in the window carefully. e Click [Yes] if you agree and continue the firmware updating. Click to continue r Select the firmware file, that has “dat” extension (e.g.: 7800_110.dat). • Click […], then select the file, as well as the location. t Type the IC-7800’s IP address into “IC-7800 IP Address” text box. y Click [Start]. Click […] to select the firmware file.
UPDATING THE FIRMWARE 16 o The screen as at left is displayed. • The following dialog appears in the IC-7800 display. RWARNING!: NEVER turn the IC-7800 power OFF at this stage. The transceiver firmware will be damaged. !0 Click [OK] to finish the firmware update. • The “FIRMWARE UPDATING” dialog as above disappears. !1 Push [POWER] to turn the IC-7800 power OFF, then ON again. Click [OK] to finish the firmware update.
ABOUT CE INSTALLATION NOTES For amateur base station installations it is recommended that the forwards clearance in front of the antenna array is calculated relative to the EIRP (Effective Isotropic Radiated Power). The clearance height below the antenna array can be determined in most cases from the RF power at the antenna input terminals. EIRP clearance heights by frequency band 1 Watts 2.1 m 10 Watts 2.8 m 25 Watts 3.
