Substantially the IC R is internally divided between a section dedicated to frequencies below 30 MHz and a section, more articulated in the conversion scheme, for frequencies above up to MHz. All mode, with IF-shift to offset the band-pass filter with respect to the tuned frequency, adjustable audio filter on two levels, noise-blanker, selectable AGC time constant, squelch, two RF attenuators, internal clock and switch-off timer. Wide range of memories collected in 20 distinct groups that can be identified by a term to five characters while eight characters can be inserted to mark each frequency, a memory bank is intended for the self-writing function that keeps track of the active frequencies during a scan, a further memory bank allows to insert the channels that the user imposes are ignored during the scan. The tuning can be set by rotary control, whose friction is adjustable, with direct input from the keyboard, or even via remote PC. Predefined tuning steps that can also be user-defined with 0.

Discover a world of information and intrigue. Government Users only Wide Frequency coverage. The IC-R covers a wide frequency range continuously from 0. Refer to the specifications for details. All mode capability Radio signals are transmitted in a variety of modes. Convenient features for receive IF shift and APF audio peak filter functions are built-in—a first for a receiver in this class. IF shift is used to reduce interference from nearby signals. It does so by adjusting the center frequency of the IF filter.
APF is used to reduce interference from signals superimposed over a designed signal by adjusting the center frequency of the audio filter. In addition, a noise blanker, RF attenuator and selectable AGC functions, clarify desired signals when experiencing various forms of interference. Ample memory channels The IC-R has memory channels providing versatile operating possibilities. Each memory channel can store a frequency, mode including passband width and tuning step, etc. To facilitate efficient use of memory channels, they are divided into 20 banks of 40 channels each plus an auto memory write area of channels.
Alphanumeric names can be assigned to the channels up to 8 characters and banks up to 5 characters for easy recognition. In addition there are 20 scan edge memory channels to store 10 sets of frequencies for programmed scan plus 1 priority channel of priority scan. And, the number of channels in each bank is user assignable. Memory editing capabilities include memory copy and paste function for easy transferring of data from channel to channel.
RSC interface An RSC serial port is located on the rear panel of the receiver for direct connection to a personal computer.
Versatile scanning functions For basic scanning, memory, priority and program scans are available. And, for more advanced needs, select, skip, auto write and mode select scans can be selected. The IC-R scans very quickly and the speed is continuously adjustable up to 40 channels per second in both memory and programmed scans with a continuously adjustable delay time.
Also, VSC voice scan control provides efficient scanning by skipping unmodulated signals. Customize the scan behavior to suit your needs. Various tuning steps Two methods of frequency entry are available: using the tuning dial or direct frequency entry from the keypad. Use the method that best suits the situation.
Numerous tuning steps are available for operating a wide variety of stations. They are 10, 50, Hz, 1, 2. In addition, a programmable tuning step is available. The programmable tuning step can be set independently for each memory channel to a value between 0. Additional outstanding features 3 antenna connectors are provided: an SO type and a phono RCA connector for below 30 MHz; a type-N connector for above 30 MHz S-meter squelch allows you to receive only those signals stronger than a pre-set level Easy to read analog S-meter and center frequency indicator Voice synthesizer optional UT required announces the frequency setting Sleep timer 30, 60, 90, min.
