Re: Recording both channels of RSPduo in dual tuner mode
Do you have any recommendations on troubleshooting this? It would be very convenient to have them scheduled to run at the same time.

Re: Recording both channels of RSPduo in dual tuner mode
Thanks for the quick reply! I guess my question is - can I schedule both the master and slave to start recording at the same time? When I try to do this, I get an error saying that it could not open a WAV file for output.

Recording both channels of RSPduo in dual tuner mode
Hello, Is it possible to record the IQ OUT data from both channels of an RSPduo at the same time? I can't get the scheduler to start recording at the same time (something about not being able to create a WAV output file). However, if I wait a second or so later, I can get both channels to record whi...

Understanding low IF mode and IQ output
I am trying to figure out how best to calculate the power and phase of two signals from an RSPduo used in dual tuning mode. I understand the RSPduo can only operate the dual tuner in low IF mode. This mixes down the raw signal to 200 kHz, correct? How would this affect the power spectrum of the sign...

Re: Getting raw IQ data via GNURadio
I've followed those instructions to the letter, and it did not prevent this issue from occurring. First, the top_block.py generated by gnuradio wasn't working, as it was returning "No module named sdrplay". After some digging I found an import statement in sdrplay_swig.py that stated "import sdrplay...

Re: Getting raw IQ data via GNURadio
Update: through some finagling and updating Python and LD config paths, I was able to get the GNU Radio Python output to *mostly* run. However, now it seems that it is not recognizing the SDRPlay on USB. A quick lsusb shows something that I believe is the SDRPlay, but all it says is "1df7". and no d...

Re: Getting raw IQ data via GNURadio
Turns out this is a moot point by now, because GNU Radio can't find the SDRPlay modules. Is anyone familiar with how to get GNURadio to know where to find to .so api/hw files? GNU Radio returns "No module named sdrplay". I can confirm that lsusb shows my RSPduo is connected as some device "1df7". Ot...

Getting raw IQ data via GNURadio
I have an RSPduo and I am trying to accomplish something that seems relatively simple - just dump the raw IQ data from the two SDRPlay RSPduo channels into two separate files. I installed the source blocks using this: https://www.sdrplay.com/gnu-radio-and-sdrplay-at-the-rsgb-convention/ However, the...

Re: Using two coherent RSP2's
Also, I was wondering if it is not possible, whether the channels within a single box are coherent?

Using two coherent RSP2's
Hello, I have been digging around the RSP2 receiver for a while now and am trying to determine if it will fit a project I have in mind. I am hoping to build a basic passive radar system using hobbyist equipment and 4 antennas (3 for detecting reflections, 1 for sidelobe cancellation from source). Ob...
