ALL BAND, ALL MODE, ALL SOLID STATE The 1C-740 covers all the Amateur HF frequencies from 1.8MHz to 29.9999MHz, including the new three bands of 10MHz, 18MHz and 24MHz. It offers not only SSB, but also CW and RTTY (FM option). All of the circuits in the IC-740, including the driver and final power stages are completely solid state, and provide about 100 watts output. In addition, the low-pass filters switched by the BAND switch and the band-pass filters selected by an electronic signal from the CPU, make a no tune-up system. OUTSTANDING RECEIVER PERFORMANCE The IC-740 employs the ICOM DFM (Direct Feed Mixer) system and up-conversion system to improve a high receiver performance. The ICOM DFM maintains a system where the incoming signals are directly fed to the first mixer, and the mixer is a high level Doubly Balanced Mixer developed exclusively by ICOM. The up-conversion system uses a high side IF i.e., 39.7315MHz and in addition high performance third over-tone crystal filters provide excellent image and IF rejection ratio. These advanced devices and system give higher spurious response rejection ratio, higher sensitivity and wider dynamic range. PASS BAND SHIFT CONTROL The IC-740 has a built-in Pass Band Shift system that allows you to continuously adjust the center frequency of the IF pass-band. By moving the control, you can eliminate interference from a nearby signal, thus providing clear reception. It can also be used as a tone control. When the PBT switch is pushed in, this system acts as a pass-band tuning system that allows you to continuously adjust the pass-band up to 800Hz from the upper or lower side in SSB and CW. The PBT switch provides better performance to eliminate interference. DUAL DIGITAL VFO WITH VARIOUS STEPS The dual digital VFO consists of three digital Phase-Locked-Loops which are controlled by the Microcomputer Control System. Three tuning frequency resolutions of 10Hz, 100Hz and 1 KHz steps can be selected with the TUNING RATE switches. Two separate VFO's can be used independently in the NORMAL (NOR) operation, and any desired in-band frequencies split transmit/receive can be used in the SPLIT (SPT) operation. MEMORY CHANNELS The IC-740 has a frequency memory for each band. Any in-band frequency of the VFO A can be stored into the memory, and it can be recalled at any time. ADDITIONAL CIRCUITS The IC-740 has a built-in Noise Blanker, VOX, CW Monitor, APC, SWR detector, and many other circuits for your convenience. The IC-740 has everything you need to really enjoy HF operation, in an extremely compact, rugged and full featured transceiver.
