The Icom IC-R71 utilizes a DFM (direct feed mixer) to make the R71 virtually immune to interference from strong adjacent signals. This, coupled with a 100 dB dynamic range, means solid performance for the casual listener or serious DXer. The receiver system is a multi-mode, quadruple conversion superheterodyne covering 100 kHz to 30 MHz with a CPU controlled, 10 Hz step VFO with 100 Hz display resolution. Advanced features include: Pass Band Tuning, IF notch, adjustable AGC, adjustable noise blanker and built-in preamplifier. The R71 also hosts a variety of user conveniences including two independent VFOs (tuners), dial lock, squelch, tone and direct keypad entry. A 32 channel scanning, tuneable memory that stores frequency, VFO and mode is also built into the R71. The rear panel has two, selectable antenna inputs: SO-239 jack and Hi-Z wire input.
