There is a fundamental lack of understanding of the SDR receiver.
?
First there is essentially no IF, its direct to base band which is the
IQ outputs.? All the work is done in the digital realm by the
ST32M4xxx mpu.
?
For second receiver the bandwidth of that down conversion is
Relatively narrow band so the panoramic view (waterfall) would
be narrow as would the frequency of the "2nd" receiver.? Doing
a close in waterfall is taking what data there is (IQ outputs)
and translating that to a display format.
?
Generally the idea of upstream tap is limited to radios that
are multiple conversion superhet transceivers.? That is typical
of many radios like ft817, FT450, IC756 and a large number?
of others.?
