Looking to play with the NEW scanner feature on SDRUNO on V1.3 ???

At this moment it does not appear that V1.3 supports anything but RSP units.

If you want to use your RTL dongle you probably need to fall back to V 1.2. You need to execute the SDRUNO.exio version of SRuno........ no scanner....then another file popup comes up and you select your ExtIO_RTL2832.dll file.

There are instructions on their website.

What’s this antenna for?

What's the purpose of the large yagi? I see them everywhere in the countryside, but almost never in larger towns or on new buildings. Many of these also seem to not be used anymore, with them being bent and having elements missing.

Is it an old radio antenna? Because there are plenty of FM radio antennas (some sharing roofs with the large yagis) that are just a circular folded dipole, much smaller than this.

I know it's probably a dumb question, but it's one of those things that I've been seeing my whole life and never really gave it any thought, until now when I got into SDR and radio

Comment on Getting the V3 Bias Tee to Activate on PiAware ADS-B Images by wiedehopf

There have been some problems reported using this method probably because of missing blacklisting of some kernel drivers.

Could you include the automatic detaching of kernel drivers to avoid those problems?
So change the “cmake ..” line to:
cmake .. -DINSTALL_UDEV_RULES=ON -DDETACH_KERNEL_DRIVER=ON

I think enabling the UDEV rules has no effect because the package is never actually installed so that part could probably be removed.

Has anyone got this combination to work successfully? I've adhered strictly to the installation article & both SDRSharp and HDSDR work, so why should I get the messge "No available RSPs found. Please check USB cables, device drivers, or if the RSP is in use in another application"?
I would be grateful for pointers as to how to fix this problem please.
