In many respects, the Kachina 505DSP was an excellent lab experiment for
Doug Smith in the design and implementation of sophisticated transceivers.
While it is a "good " radio in most respects, the ORION can be expected, in
comparison, to be a SUPERIOR radio.
The physical construction of the 505 with its motherboard and heavily
shielded plug-in modules is a study in compact construction with minimal
crosstalk and other internal RFI problems.
