Re: Yaesu FT-818ND Discontinued Manufacturing

Just for information a rig that is SDR does not mean it has tunable filters or newer tech except it is more of being computer controlled.? SDR means the operating system is in firmware and can be updated usually with a SD memory card.
The tech for tunable IF/direct sampling filters and other newer operating parameters like noise reduction is in DSP, Digital Signal Processing.? This is done in hardware.
Today few rigs are not SDR and most have DSP, some at the IF level, few like the IC7300, IC7610, FTDX101 at direct sampling of the incoming signal.? Other older rigs like the Icom IC756Pro, IC7200, IC7410, FTDX10, X6100, and G90 and some others have DSP at the IF level.? Icom had IF DSP with the IC756Orig serues in the 1990s when Yaesu was still working with IF filters as in the FT1000 series.
