Sorry if i post this wrong. I can’t find this question anywhere.

Here is the ground frozen at the moment. So no copper grounding rod. Is it possible to nail ground to a tree. A living one.


Hi, just bought a RTL-SDR Blog V3 R860 RTL2832U 1PPM TCXO HF Bias Tee SMA Software Defined Radio with Dipole Antenna Kit off Amazon, and I watched a video on how to set the device up and install the drivers, and it worked, but as soon as I move the Mouse on the Freq Display the program crashes showing “Unknown Hard Error” ????
I’m running the latest Windows 11.
I’ve tried different USB Ports and the same thing happens, I’ve tried reinstalling the software and the same thing happens as soon as I use the mouse to change the Freq or move the mouse across the Freq display the error pops up and the SDRSharp crashes…

I’ve managed to download a version of SDRSharp called “sdrsharp-x86-noskin” and that works fine no problems at all ???

Any ideas why the latest version crashes ?


Hi, I’m new to the world of SDR & need help with getting software to run. I have a Linux Mint machine & I’ve no idea what I’m doing. I download packages that seem to need more & more packages, yet I always end up running into fatal errors, sooner or alter. I’ve been trying for 3 weeks.

Is there any SIMPLE way to get GQRX or Linrad to work? I read user comments that say “Had it up & working in 2 mins” but I can’t find anything that deals with the problems that I’m facing.

At this rate I’m going to have to dust off my old Icom RC8500 & repair it.

Thanks for your help.

I just received an RTLSDR+ upconverter from an estate sale, I know nothing much about it. What software do I need to use to make it operate. On top of the unit it says 100khz to 1.7GHZ Very wide SDR receiver and has two sma connectors.

I am picking up sound from the room when my stereo-amp with two speakers is on so I get a strong feedback-loop when I listen to my RTL-SDR. I can hear the echo when I tap the amp.
It spawns strong frequencies everywhere from 50mhz to near 300mhz. Can someone explain this? It would be much appreciated!

Scanning stops and I get “CAN NOT ACCESS RTL DEVICE”. This error is not listed in the RTL-SDR book. Can anyone help?


I cannot get the digital portion of SDRSharp to work. After installing the simulated audio cord it no longer allows me to access the set up to put it in “Record”. I am using a Dell Inspiron 15 with Windows 10
