[Elecraft] K3: A question about the low IF and IF image freq.

[dj7mgq at muenchen-mail.de]

Hallo,

a minor discussion has popped up here in DL about how the K3 mixes down to 15kHz
before going to the ADC. 

There a few who are worried that the level of rejection +/- 30kHz from the
8215kHz IF will not be "good enough", due to filter blow-by, to prevent strong
signals being heard on the image frequency of 8215kHz. This has lead to
speculation about if the K3 uses a scheme which produces I and Q signals at
15kHz, which would allow the DSP to further suppress the image reception.

The FAQ is not very clear about how the mixing down to 15kHz has been designed. 

Maybe one of the beta testers could answer this. 

I wouldn't want to slow down Eric or Wayne,
