[Elecraft] OT: DZKIT Sienna?

[Wayne Burdick]

Hi James,

The Sienna is an interesting design, and I believe it's available in  
kit form. I've met the designer, a very capable engineer.

Given my inherent bias, you can take the rest of my comments with a  
grain of salt.

The rig is vastly different from the K3. The K3 has about 20 dB  
greater blocking dynamic range, about 15 dB better IMD dynamic range,  
narrower roofing filter options, and half the receive-mode current  
drain (about 1 A vs. 2 A). The Sienna appears to lack a sub receiver  
or even a dedicated second VFO knob, and uses audio DSP rather than IF  
DSP, limiting its feature set (as the web site mentions, it is analog,  
not an SDR). If I'm not mistaken, the VFO uses a DDS without a PLL,  
which may explain the dynamic range limitations.

Now I'll get back to work and let those with actual experience with  
the Sienna take over :)

73,
