[Elecraft] SDR-IF and I/Q questions

[Richard Fjeld]

Larry,
Thank you for the suggestion. That could be possible. I'd hate to remove the Z10,000 
Buffer/Amp to change out a SMD component, but that may be what I will have to do. 
My Z10,000 is set for 0 dB gain at present.  I just e-mailed the Google PSDR-IF group 
a question about an observation I have made. It may be totally in the wrong pew, but 
you may want to look for it. And, it may reveal something I am doing wrong.

Thanks,

Dick, n0ce

Dick, if some programs work, then your levels may be low. PowerSDR/IF 
and NaP3 use an algorithm developed by Flex Radio called WBIR (Wide Band 
Image Rejection). It does a phenomenal job of eliminating images (>80dB) 
but is sensitive to levels, requiring a minimum amount of total signal 
power in the display to work. Since you say that other programs work, 
your issue may be levels.
