Tranciever Тюльпан-DSP

[UA6VAE]

Faced with a strange problem.
As I connect the DDS output to DDS(4) through NB3N3020 what I should use as DDS mux and Frequency factor?
I used 4 (DDS mux) and 1 (Freq factor) at this moment and heard very weak tone signal when test with Tone button and my scanner.
When i feed TRX with line in source i saw on FFT window actual signal pattern but heard nothing with scanner...
