This is awesome! I'll definitely try this out soon. I use one off python scripts to find the sample offset and the small residual center frequency difference. This simplifies the process significantly. 

This should make it much easier to implement a passive radar block, or an interferometry block.

Hi all,

I want to announce new GNU Radio related project prepared by me - Multi-rtl:

It is a Gnu Radio block that combines multiple RTL-SDR receivers into
one multi-channel receiver.

Only hardware modification to RTL-SDR dongles required is connecting
them to a common clock source (i.e. one of the dongles' oscillator as
Juha Verinen showed once). Each channel can work on a different central

Everyone who wants to know how it was achieved is invited to read my
