That was two dongles sharing a clock. Not exactly daisy-chained, and it
didn't look easily extendible :)

We must not forget that each device has its own USB connection.
One reason that getting all in sync on a ' per sample' base must be
impossible.
Still a multi user system like the websdr can achieved by overlapping the
channels and let the software decide what channel the user's choice fits.

How about the PFB synthesizer detailed by TR? I'd think all the dongles
would have to be phase locked and references tones (or comb) used to
calibrate the channels. If your signals are not crossing channels then
maybe you could get away without that.

Thanks a lot, it really got me going! This is part of my learning process,
if it's leading to nothing at all; that's okay.
Somewhere I red about feeding multiple dongles from a single signal
source, interesting
A possible configuration:
1. Upconverter & 30 Mhz low pass filter
2. Cheap wideba

If you make an FFT block for each rtl-sdr source you can then interleave
them all together and take your pick using the 'M in N' block. At the edges
of each rtl-sdr frequency it will probably get quite messy as the clocks
are not synchronised.
An example of the use of the FFT and 'M in N' blocks i
