Re: My dongle doesn't function

Then it's possibly a hardware fault. Contact NooElec about a replacement.

All RTL-SDRs regardless of the brand will work the same in GNU Radio. You just need the RTL-SDR source from gr-osmosdr.

Re: "RTL SDR dongle not working as expected" - SDR noob questions.

If you're just starting out, then it's best to start with a program with a GUI like GQRX or CubicSDR.

Re: Reverse engineering the demo software

So the new code is being worked on now, and that will be quite a bit more advanced, but also fully documented. For now this is a brief overview of the current code: rtl_daq: Yes this takes a chunk of data from the RTL-SDRs and buffers it sync: Synchronizes the samples based on the USB delay determin...

Re: Setup issues

There seems to be a bug with the latest web code where the checkbox unchecks if you use that button. Just enable them manually using the checkboxes and the Update button for now.

Re: New Antenna for Kerberos SDR

Very nice! Going to order some to test out. Dipoles definitely do work best, but it can be hard to use them on a roof of a car while in motion for example. But for a fixed site this will be perfect.

Re: NOAA and Raspberry Pi Help
