![]() ![]() As a result of this design, the purity of the LO achieves a Reciprocal Mixing Dynamic Range (RMDR) of 110dB. With the design of the IC-7851, Icom's engineers focused on a new Local Oscillator (LO) that drastically reduces the phase noise. However, what happens inside the radio with all those signals coming down your feedline can defeat all your efforts. Larger antennas, higher gain pre-amps and other devices in line are great. Solid design basics and HF expertise raising the barĬontesters and DXers are always looking for that competitive edge to magically pull out the weak signal that is either the rare country or multiplier they need to climb up the list.
