[hpsdr] QSD architecture and image suppression

[Oleg Skydan]

Hi, All!

I have seen a lot of different projects/radios based on QSD.
I understand that most parameters can be at a competitive 
level with traditional designs, but it is still not clear for me
how well the image suppressed? 

I understand that you can get a very good image supression 
(80-100 dB is real) for the limited time with stable temperature 
and etc. But I wonder how well the image is suppressed with 
all this parameters from the real life (at least with time/temperature 
influence)? 

All the best!
Oleg
