If your listening to the low bands then your either using an upconverter or your using direct sampling. You didn't capture the RTL dongle setup window whereby you select what sampling rate, and RF gain, direct sample ..etc

Re: rtl-sdr error in linux on Orange Pi: Detected Kernel usbfs mmap() bug, falling back to buffers in userspace

A question.... how did you install rtl-sdr...compile yourself or package software management?
You mention rtl_433 as part of a package. Please elaborate a little on this...

Re: downloading CubicSDR to Raspberry Pi 4

I just went to that site. It looks like a windows only app.

Scott, are you using a Ryzen based processor? may need a different libusb-1.0 file SDR console , I believe is fully self contained. I don't think you need any extra files or drivers... I have concerns about your 64 bit driver statement. ....just because you have a 64 bit machine, doesn't mean everyt...

Re: RTL-SDR v3 adapter does not show in 'lsusb' after running "rtl_test -t"

You said your using the V3 dongle. Don't use the -t switch..just rtl_test. Won't solve reg problem.
lsusb stuff....... I suspect you haven't done the blacklisting part of the easy setup guide.
Powered usb3 hub is your best shot. I have a pi4 and running 3 V3's on the usb3 hub.

Re: GNU Radio AM broadcast rx example not working with rtl-sdr blog v3 dongle

Sorry to say , but that's a very poor antenna for those bands.....Even a 1960's transistor radio had a better antenna.

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

Just FYI, Linux has a very good TV app called kaffeine. It has a built in channel scanner and I have used it, but not on a rtl2832 unit.
