Perhaps that's what JohnP was suggesting.
But I assumed he was talking about some other IF,
as the 434mhz IF on the tinySA is definitely not below 50mhz.
As Erik says, an 8 bit A2D has a dismal dynamic range.
So results won't be great, but could be at least "interesting".

Might be interesting to put a DVB-T SDR dongle on the tinySA's 433.92mhz IF,
you could listen in as the tinySA slowly sweeps through a ham band.
The inverse of that panadapter idea.

Great call, I've been thinking about this recently (along with coupling to prevent adverse signal effect) and also wondering about the other way around for tapping the signal to perform demodulation as a receiver project.?
If you want to demodulate signals, a better approach might be to use an SDR on the IF; you'll most likely need an attenuator and maybe an up-converter as the SDR dongles don't work below 50MHz without some trickery. There are any number of SDR control programs out there (HDSDR, SDR#, etc.)?that will give you a waterfall?display as well as the spectrum as well as the ability to listen to any type of modulation.
