[Elecraft] KX3 "Full" SDR

[Bruce Beford]

Many people seem to be either forgetting, or missing the point of Leif's
article (referenced below). The entire thrust was in the context of using an
HF transceiver as an IF rig with VHF/UHF/SHF transverters. Band noise on
those higher freqs is low enough that transmitted phase noise can be an
issue. This is especially true when running high power.

His summation was that the Flex-1500 is marketed as being perfect for
driving microwave transverters. His article outlines why this may not be
true. The FLEX SDR radios are not as objectionable on the HF bands, where
atmospheric and other noise dominates.
