1、HF TRANSCEIVER The IC-78 is a high performance HF transceiver. Innovative features such as 99 memory channels, high C/N ratio, direct channel entering, data com- munication capabilities and more, offer easy operation for anyone. All these features come in a compact, rugged package that can be conven

2、iently used in a base station or in a vehicle, as you prefer. Reliable straight forward HF communications With the speaker facing the operator, audio sounds can be clearly heard without im- pediment during operation. It is no longer necessary to manually increase the volume to try and capture audio

3、sounds. When the optional CR-338 HIGH STABILITY CRYSTAL UNITis installed, it allows up to 0.5 ppm of extremely high stable operation. Durable, powerful construction Flexible filter selection High frequency stability Front mounted loud speaker An optional IF fi lter can be installed into the transcei

4、ver, providing 5 passband widths selectable in SSB, CW or RTTY modes. VFO mode operation* For continuous frequency operation, VFO mode operation* capability is available. It is convenient when searching for signals, around the programmed frequencies, such as short wave broadcasts, etc. *depending on

5、 version Superior basic performance A 4-element system is employed for the 1st receive mixer, providing superior receive IMD, especially from in-band, nearby inter- fering signals. A well-designed double-con- version system to help minimize image and spurious responses for better signal fi delity, i

6、s also built-in. A newly designed PLL circuit has been adopted to improve C/N ratio characteristics. The combination of the 4- element system mixer and new PLL circuit allows superior basic performance. An affordable 99 duplex memory channels are available for storing individual transmit and receive

7、 frequencies, operating mode, fi lter setting, as well as 8-character channel names. You can enter channel assign- ments easily from the 10-key pad. In addi- tion, an extra 1 call memory is available for storing the most often used, or most impor- tant frequency. An independent, one-touch recall swi

8、tch is available. The IC-78 is equipped with a large easy-to- read LCD. A minimum number of switches and controls allow for superior feature se- lectability. Keys access functions directly theres no secondary function key. You can enter your operating frequency*, or mem- ory channel number directly

9、from the 10- key pad. *depending on version Simple operation Ample 99 channels with 8-digit channel name capability The IC-78 delivers a powerful 100 W of out- put power, providing the talk power you need to reach the most distant locations. Its one-piece, die-cast aluminum construction combined wit

10、h a large heat sink, helps keep internal temperatures down and en- sures that operation is stable at high duty cycles. And its compact size of 240(W) 95(H)239(D) mm* makes installation easy. *9716(W)334(H)91332(D) in. Direct channel selection A 10-key pad has been adopted on the front panel. A chann

11、el number, or an operating frequency*, can be entered from the keypad directly. Also, memory channel editing is possible. A large channel selector and up/down keys are available to suit your operating style for your convenience. Total and simple oper- ation is provided! *depending on version Cloning

12、 capability Programmed data cloning capability between transceivers is available, so that an identical transceiver set- ting can be made immediately. Built-in 2-tone alarm* The 2-tone alarm for an emergency signal transmission is built-in*. Inde- pendent tone switch is adopted for quick and simple e

13、mergency calls. *depending on version Data communications In addition to the current voice and key operation, FSK (First Shift Keying) type RTTY mode is available. By connecting a terminal unit or termi- nal node controller to the ACC socket on the rear panel, data ac- quisition and text-base fi le

14、transfers and other data communication can be made. On RTTY, shift width, tone frequencies and polarization are also selectable. Superior features support serious communications Noise blanker To reduce pulse-type noise, a level adjustable noise blanker is built-in. Various levels of pulse-type noise

15、, such as from car ignitions, etc., can be reduced. Pre-amp. and attenuator A pre-amplifi er and an RF attenua- tor are adopted for more pleasant reception. Convenient when weak signals or extremely strong signals are received, to present better qual- ity readability. SQL/RF gain controller In addit

16、ion to the squelch control, an RF gain control is available, and the controller is combined with the squelch control. The RF gain ad- justs minimum response receiver gain, and ignores signals weaker than the pre-set level providing pleasant stand-by, or scanning. The SQL/RF GAIN controller action is

17、 selectable from squelch only, RF gain only or combined, in the SET mode according to your operating style and mode.
