Hi Don,
If you look at the Paragon you see that processors have begun to 'take over'
for some of the functions of things like bandswitches, frequency stability
and frequency selection which begin to change the 'look' of the transceiver
relative to its predecessor, the Corsair. The Omni series that succeeded the
Paragons took processor control several steps further to include frequency
synthesis combined with crystal phasing, notches, and audio dsp filtering.
The Pegasus and Jupiter took this idea of processors further still to
include frequency synthesis and digital control of everything else (without
crystal phasing), using analog-to-digital processing and back again,
including the functions of sideband generation and phasing, bandpass
selectivity and audio output. In order to assure control of the processors
interacting predictably, the firmware which resides in read only memory is
given the job and must be booted each time the rig is turned on, or should
it become unstable.
The Argo V is a lower power version and something of a combination of
previous Argo rigs and the newer SDR way of controlling function.
So, while the Paragon and Argo have similarity in what they do, they differ
considerably in how functions are carried forth. What they have in common is
quiet, yet hot receivers, flawless QSK, impeccable stability, unimpeachable
selectivity along with general coverage capability.
Im not sure I answered your question to your taste, but I took a shot.
