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.

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.

Re: Installing RTL-SDR: Cmake error - LibUSB 1.0 required to compile rtl-sdr

I have and use vmware. Did you download the vmware version of Kali2020, or plain iso?
I'll try it by tomorrow night. It's slow downloading.

I would have bet the farm that libusb wasn't there :>} ..... I am curious about libusb1-0 vs -dev .. thing happening...

libusb-1: /usr/include/libusb-1.0

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

I see your working to get down in the AM, but how about trying to see up in the 7 and 14 Mhz area using direct sampling 2 or 3 and see if there is anything there.

Re: blue screen restart

I would say at this time to NOT install the community package. If sdr# crashes on startup, I doubt zadig is even involved yet.
After reading your entry again, I see its win os that's crashing..getting tougher now..

Install a new sdr# into a new different directory. If you overlay it on an old build there may be artifacts from original install
