[Elecraft] K3 and whats next from Elecraft

[ab2tc]

Hi,

No, no crystal filters in a "pure" SDR. But if they sampled after the 1st
mixer but before the roofing filter bank, maybe. If Elecraft added
demodulator software and an audio output to the P3 that's exactly what the
combination would be. Being able to display and record a significant portion
of the HF spectrum plus the ability to demodulate very wide modes such as
wideband FM is what is expected from a more or less "pure" SDR. The
remaining K3 analog front end including the RF filters, attenuator and
preamp would go a long way to make the A/D converter having an easier way.
