I too visited the ELAD booth, and helped demonstrate features to the curious.

For what it is worth, the Hamvention gave definite proof that all manufacturers have switched to SDR architectures, including Elecraft. They are abandoning their traditional architecture and gone entirely SDR. The new K4 has nothing in common with the K3 line.

Apart from the K4's optional superhetrodyne front end... :>) Not totally abandoning the past...

I quote "The K4HD in turn builds on the K4D and additionally offers a dual superhet module (for main and sub-receivers). Only the 8MHz IF is then sent through the ADC - the result is excellent dynamic range and excellent high-signal strength. "
