[Elecraft] K3: Jack's latest measurements

[Jack Smith]

Doug:

I'll run that combination over  the weekend and add it to the page.

If someone who enjoys Windows programming would like to work with me, we 
could easily develop a simple utility program so that anyone could 
generate these plots for their own K3 filters. It requires a low phase 
noise signal such as a 10 MHz reference from a frequency counter, but 
nothing else beyond a K3.

The program I've written is pretty crude in Liberty Basic and requires 
post-processing in Excel and then Origin to generate the plots. It could 
all be combined into a Windows program but writing Windows code is about 
as low on my list of enjoyable activities as it goes.
