[Elecraft] Re: K1 and KX1 Compared

[Wayne Burdick]

Hi Bruce,

Thanks for posting this comprehensive comparison.

I would add just one further point. Since the K1 has an analog L-C VFO, its
spurious-free dyanmic range is larger than the KX1's DDS VFO. The same would be
true in comparing any L-C vs. DDS implementation. 

In typical field operating circumstances, the KX1's DDS VFO does very well; the
simplicity, wide tuning range, and low current drain of DDS is ideal for a trail
radio. But the K1 receiver would have the edge in some cases, such as in a major
contest where most of the stations were operating at high power levels. The
better the SFDR, the less likely you are to suffer from a general increase in
IMD. 

This is one reason we consider the four-band K1 to be an ideal home QRP CW rig.

73,
