The AD9834 DDS chip in the KX1 is clocked at its maximum rate of 50 MHz.
The highest relatively clean frequency that can be generated from a DDS is
about one-third of its clock rate (about 16 MHz). Thus, the KX1 design
can NOT be adapted to cover ham bands above 20 meters.

I wonder if it would be possible / practical to replace the KX1's AD9834 DDS
chip with another type such as the AD9951 which can be clocked up to 400+
MHz, perhaps lack of space could be a problem.
