Is Meteor M2 alive?

I'm not sure if my setup went bad. I don't even see any single signal at all.

Antennas • Satellite dish as a directional antenna?

Hey,
I’ve got a somewhat large satellite dish on my roof that I don’t use for TV anymore. I was wondering if I could replace the small satellite receiver with my own anttenna (like a simple dipole) and use it as a directional antenna.

Troubleshooting Help • Dropped samples

Hiya

System :

AMD Phenom x4 Black edition 9850, 24Gig ram, auto speed up to 4.1GHz. Windows 10 professional latest creator update.

I have 4 v3 rtl-sdr dongles which I have connected individually to USB2 and USB3 ports, USB2 and USB3 via a hub both single and all 4.

I have successfully installed the drivers, renamed the dongle serial numbers and they are recognised by software.

However I can't run a sample rate on any of them in any of the above combinations above 1.0Mbs without getting a massive continuous packet loss shown by rtl_test -s 1000000 -d serial number.

I have googled extensively and have found no clear answer to this problem. Surely a 8 thread processor running over 2GHz should be able to run one dongle at 2.4Mbs??

Any suggestions please - ?

Cheers

RTL-SDR Discussion • Damn, this ADSB preamp

Why is this so good?
And why does it feel even better when one looks at the Uputronics preamp prices?

Test location, 40 feet of concrete 180° behind the FA antenna with the rtl-sdr v3 dongle + adsb preamp. Poor location.

You can see the antenna deaf spot between 95° and 140°.
This is off the chart performance for me.

4 contacts at 420 Kms!
I can't wait to move the setup to it's final location which has good height and no real obstructions.
