A digital AFC function tunes the receiver to the center of FM or WFM signals. In addition a noise blanker, RF attenuator and selectable AGC functions clarify desired signals when experiencing various forms of interference.

It is also useful in other modes as a tone control. The APF is especially useful when receiving CW. It does so by adjusting the centre frequency of the IF filter.ĪPF is used to reduce interference from signals superimposed over a desired signal by adjusting the centre frequency of the audio filter. IF shift is used to reduce interference from nearby signals.

IF shift and APF (audio peak filter) functions are built in. The IC-R8500 has superb high receive sensitivity over its entire range, and built in high quality crystal (TCXO) provides excellent frequency stability of less than +/- 10Hz below 30MHz less than +/- 3ppm above 30MHz. Several speciality modes such as CW narrow, AM wide, AM narrow and FM narrow are available to receive a variety of signals that require a matched passband width. SSB (USB, LSB), CW, AM, FM and WFM are included. The IC-R85000's all mode capability allows you to receive signals in many different modes. The programmable tuning step can be set (independently for each memory channel) to a value between 0.5 ~ 199.5Khz in 0.5kHz steps. In addition, a programmable tuning step is available. Numerous tuning steps are available for operating a wide variety of stations. Two methods of frequency entry are available using the tuning dial or direct frequency entry from the keypad.

You can be sure that if there are any communications or broadcasts out there, you'll be able to hear them with minimum interference from other signals. The IC-R8500 covers a wide frequency range from 0.1 to 2000MHz, with 10Hz resolution, while maintaining high receive sensitivity. The IC-R8500 is not simply a scanner, it is a professional quality communications receiver with versatile features that will appeal to both the serious receiver enthusiast or professional user. The IC-R8500 covers a wide frequency range from 0.1 to 2000MHz (with 10Hz resolution) while maintaining a high receive sensitivity. IC-R8500 Communications Receiver (Discontinued)
