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. Alphanumeric names can be assigned to the channels (up to 8 characters) and banks (up to 5 characters) for easy recognition. To facilitate efficient use of memory channels, they are divided into 20 banks of 40 channels each plus an auto memory write area of 100 channels.
Each memory channel can store a frequency, mode (including passband width) and tuning step, etc. The IC-R85 memory channels providing versatile operating possibilities. 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. The APF is especially useful when receiving CW, but is also useful in other modes as a tone control.
APF is used to reduce interference from signals superimposed over a designed signal by adjusting the center frequency of the audio filter. It does so by adjusting the center frequency of the IF filter. IF shift is used to reduce interference from nearby signals. IF shift and APF (audio peak filter) functions are built-in–a first for a receiver in this class. The crystal is the reference for the PLL and DDS circuits to achieve these specifications. The IC-R8500 has a superb high receive sensitivity over its entire range, and the built-in, high quality crystal (TCXO) provides good frequency stability of less than ☑00 Hz below 30 MHz less than ☓ ppm above 30 MHz.

The optional TV-R7100 TV/F, adapter allows you to view TV broadcasts (when connected to a CRT monitor) and listen to FM broadcasts. SSB (USB, LSB), CW, AM, FM and WFM are included, and, several 'specialty' modes, CW narrow, * AM wide, AM narrow and FM narrow are available to receive a variety of signals that require a matched pass band width. The IC-R8500's all mode capability allows you to receive signals in many different modes, from the world over. Radio signals are transmitted in a variety of modes. 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 continuously from 0.1 to 2000 MHz, * with 10 Hz resolution, while maintaining a high receive sensitivity. Discover a world of information and intrigue Wide Frequency coverage.
