selectivity of IC-7800 is far better than that of the IC-781, and its IF-DSP filters are much tighter than the analogue filters in the IC-781. If DSP NR is ON and a tighter roofing filter (e.g. 3 kHz) is used, the IC-7800 is an even better performer. If you need to hunt weak DX signals among “big guns”, IC-7800

IC-7851 IC-7800 IC-7851 IC-7800 Design advances developed by the Icom HF engineers for the Local Oscillator (LO) enable the IC-7851 to set a new benchmark for amateur radio receivers. The goal was to dramatically reduce the phase noise that degrades the target signal due to the sum of the entire signal pres-ent. The result was a RMDR of 110dB*.
