Paul, I would not regard 100 Hz of drift in the K1 as a design problem at all - The K1 spec is for drift less that 200 Hz after a 5 minute warmup.
The fact that the K1 does not use a DDS vfo is not a 'design problem' as was stated, but surely was a design decision based on price/performance with components available at the time it was designed. At the time the K1 was designed, DDS units were not as available as today and were still quite pricy - by the time the KX1 was designed, the cost of DDS had dropped significantly. I fail to understand how anyone could refer to this a 'design problem'. 73, Don W3FPR > -----Original Message----- ...snip...
