[Elecraft] K3 RX Equalizer

[Lyle Johnson]

The K3 filter is a little unusual in that the receiver equalizer is part 
of the DSP bandpass filter, not a different or subsequent filter.  This 
helps minimize latency.

As a result, the equalization is applied before the audio paths are 
separated, so it is on all receive paths.

In data modes, the equalizer is disabled (the filter coefficients are 
re-computed ignoring the equalizer settings).
