Re: Wonky L-Band patch antenna

I believe that they will set value the value below $1 which is the new threshold, and labelled as a free warranty replacement. So that should not be taxed. It will ship with Fedex or we'll import the replacement locally to the EU first and pay any taxes then. If something goes wrong with the tax and...

I ran IF average and get a similar peak, although it is smaller due to the lack of tuning.
Got a screenshot?

Re: SDRSHARP close in a few minutes

Did you install the 64-bit or 32-bit NET5 redis?

Try reinstalling the 32-bit version https://dotnet.microsoft.com/download/d ... -installer

Re: What is the frequency of these spy cameras

Do you have access to the toy? On the back or in the manual there should be an FCC ID number that you can look up.

Re: Wonky L-Band patch antenna

So unfortunately on the very last 100-200 units made in the first batch of 1000, the factory seems to have made some error in the plastic formulation, or heat treatment of the lids. The bases appear to be fine but there is some unknown percentage of those 100-200 lids that deform at the slightest am...

Re: Hydrogen Line Band Interference

I'm not seeing any Hyrogen line there unfortunately. Those tall peaks are just noise, or the center DC spike. It's really unlikely that you're getting the Hline without a good LNA. The Yagi will also need to be tuned for 1420 MHz, and pointing at the milky way to have any chance at seeing something....

Re: rtl_fm wrong frequency

Take a look at the examples here http://kmkeen.com/rtl-demod-guide/ The problem might be something to do with the resampling or sampling rates your setting. I'm not sure how rtl_fm reacts to changing those with wbfm as the demod mode. Also the "Tuned to 89.836000 MHz." is correct. The SDR will tune ...

Re: not working

Usually just windows update overwriting the Zadig drivers. Rerun Zadig and reinstall the drivers, and it should work again.

Re: RTL-SDR Local airport not coming in at all (AM)

Do you have line of sight to the tower, or at least aircraft? Zoom out and look for other active frequencies too. For airband make sure you're using AM demodulation. And get the antenna outside, and the long elements almost full extended.
