Predefined tuning steps that can also be user-defined with 0.5 KHz resolution. The tuning can be set by rotary control, whose friction is adjustable, with direct input from the keyboard, or even via remote PC. 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. 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. Substantially the IC R8500 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 2000 MHz. The ICOM IC-R8500 is a receiver with plenty of functions, far from complex to use, with some important points in the controls management being equipped with a rational front panel. This parameter, not in official data, was obtained with direct tests.0.1 ~ 1000 MHz and 1240 ~ 1300 MHz specifications guaranteed.± 3ppm with temperature from -10☌ to +50☌Īux (AGC / unfiltered FM discriminator output) User-defined 0.5~199.5 KHz with 0.5 KHz resolution

It combines the functionality of a HF radio set with those of a advanced scanner. Triple-conversion desktop receiver, frequency range 0.1-2000 MHz all-mode.
