that is where you have a common clock distributed to the RTLs
"A single 28.8 MHz reference clock is distributed to all dongles. "

What I want to do is have the dongles completely independent running 
with their own computer off a battery.  Capture the data to a SDcard 
and then post process it to do the interferometry


And do this with a self contained calibration approach (i.e. not depend 
on there being a convenient radio station which has a signal in band, etc.)
