This item comes with our in-store 30 day warranty. This is the same 15kHz crystal filter used in the IC-7800 roofing filter circuit. Although it’s more expensive than overtone-mode filters, the fundamental mode filter has a better shape factor and is less susceptible to intermodulation distortion under strong signal conditions. i give the now long discontinued icom ic 756 pro ii 2 a luke warm thumbs up for shortwave listening use due to it is fair to poor receive audio quality the. Large inductors can handle both strong signals and weak signals with lower distortion. The IC-756PROIII uses a fundamental mode monolithic crystal filter for the roofing filter. To achieve this goal, Icom used higher-grade components in vital receiver sections of the IC- 756PROIII. The IC-756PROIII uses large inductors instead of small coils in the bandpass filter (BPF) stage, because small coils sometimes cause magnetic saturation in the BPF stage. Using receiver design techniques introduced in the IC-7800, Icom’s engineering team focused on producing a distortion-free, high-dynamic-range. ![]() Included with the radio is the original manual, hand mic, and power cord w/ PowerPoles. ![]() The connections on the rear are clean as well. ![]() The display is in good shape and the text on the front is all clear. This radio is free of any damage, but does contain some dust on the front buttons and dials. U8235 Used ICOM IC-756 Pro III HF/50MHz All Mode Transceiver
