Hi,

Is it possible that you can provide some brief documentation on how to use this application?

I have the hardware all built (with the noise / signal switching working and the shared clock), and your code detects all three dongles and seems to run successfully, but in the waterfall visualization there is no green blob corresponding to the angle of arrival. It seems like it's just a green vertical bar of dots which doesn't correspond to any specific angle. I'm using three antennas in the same orientation (and almost the same distance from each other) as your pizzabox setup, and I've updated all the coordinates to reflect my setup. Even after I got the inter_df.py compass script working, it just jumps all over the place instead of showing one direction.

Do you have any advice for how I can get it working? Thanks!

Hi tejeez,
I am trying to implement it myself, but I don't understand where the "USB data(for noise)" on the switch board will connect to. It seems it will connect to a noise source, so where is the noise source schematic? Is it connected to another port of USB hub?

Hi @tejeez, I'm trying to find your contact information (e-mail) but I'm unable to find it. Yesterday I've released Multi-rtl (https://github.com/ptrkrysik/multi-rtl) project that automatically synchronizes RTL-SDR dongles and also yesterday I discovered that you are working on something similar. Maybe we could exchange what we know and both benefit from it.

Hoping someone can advise or help ???

Hello,
I am trying to use this software to sync my 2 haked RTL receivers.
I can see that is is build and configured specifically for project that is described in README.
How I can use it, just to sync receivers and run rtl_tcp?

Thanks in advanced.

Now that KerberosSDR is available, it'd be neat to have the waterfall visualization working on the hardware. I'll probably look into it as I've got the kit now and I'm already familiar with the DF Python code.

Hi Tatu!
What a great project! However, the antenna switch PCB (or whatever it is on that picture) is very unclear. Do you have any CAD of that or do you know of any? I think your design with the new noise source would be a great project for a complete small box design, possibly improving performance by more exact traces etc. I'd be happy to contribute to such a design project if you are still interested.

Got it running with ./run.sh, but how do we use your inter_df and music_df Python files? Trying to set up something similar to what you have in your video.
