Re: R820T3 ?

Interesting find, i'll look into it. My guess is that because they've stopped selling the R820T2 for normal TV tuners, and it's mostly used for SDR now, they're just calling it the R820T3. Remember the only difference between the R820T and R820T2 was the place they were manufactured at, and the sili...

Re: Driver installation failed on Windows 10

Do you have an antivirus running that could be blocking custom drivers from being installed? Check your AV logs.

Otherwise there must be something corrupted or strange on your PC if neither Zadig nor USBDriverTool is allowing the files to be installed.

What is the error message? Have you been through our quickstart guide at www.rtl-sdr.com/QSG?

Re: Do I Need To Determine PPM

No need to find the PPM offset with V3 dongles unless you really need great accuracy. The V3 will only be up to 2PPM out which is small, and won't drift much from there.

Re: Spikes on HF frequency

Those spikes are probably from computer noise, or perhaps from the dongle itself. They will normally go away once an antenna is connected. But the antenna you're using is not for HF signals (you seem to be using the dipole?). The dipole is only sized for VHF/UHF signals. For HF you need a large ante...

Re: Strange Display SDRSharp

Looks like there might be a strong signal overloading the LNA or RTL-SDR. Can you tune around and see if you see anything really strong? I've mentioned this a few times, but I think an LNA is not really needed for 137 MHz, unless you have really long and lossy coax cable runs. Adding in an LNA for 1...

Re: GPS reception (rtl-sdr v3)

I could never get gnss-sdr to work either.

If it's all the same, try this tutorial with RTK-NAVI and gnss-sdrlib https://www.rtl-sdr.com/rtl-sdr-tutoria ... -plotting/. That one works for me, although it is still a bit buggy and the lock is only stable for 20 minutes.

Re: Has anyone managed to get a Raspberry Pi 4 working with an RTL SDR?

Still waiting on my Pi4 to arrive.

But I have everyone who already got their units complaining about this, so something is definitely wrong with the Pi4 and RTL-SDR at the moment. Most likely just a software issue that can be fixed in the future.

Re: More fake units sold on Ebay

I bought from trademe.co.nz a device reputed to be an RTL-SDR v3 which differs in a number of respects from the pictures shown on the RTL-SDR.com Blog sales sites on Aliexpress and eBay. The most obvious differences are that it has an electrolytic capacitor adjacent to the "TCXO"" and that the date...
