KerberosSDR • Re: Bias-T on KerberosSDR?

OK, so are the antenna inputs decoupled or do I need to protect them from DC on the coax?

Just asking, I guess I'll go for an LNA (or rather four of them) that has an external bias input and feed the power to the LNA via a separate line.

KerberosSDR • Single radio failure on my KSDR?

Hello, this is my first post on the rtl-sdr.com forums!

I received my KerberosSDR about a month ago and I have been having a great time learning about RDF and SDR.

However, it looks like the first radio has developed a fault.

I can see the blue light for radio 1 come on when I set the DIP switch, but it no longer appears as a USB device (using lsusb).

There is no problem with the other three radios.

I have tried it on my Ubuntu PC and my laptop but radio 1 doesn't come up on either device.

I have visually inspected the PCB but I can't see any obvious faults with components.

Has anyone had a similar issue, or can anyone suggest fault-finding or repair steps? I would be very grateful for any assistance!

I enjoy his videos very much, he is a fountain of information on SDRs. Excellent work, keep those videos coming and thanks.

SAR & Air to Air Frequencies Europe

I live in the south of Spain, and frequently see military and SAR aircraft performing searches in the Med Sea. What frequencies could they be using, potentially for coordination? I have tried 123.45, 122.75 and 243MHz but with no traffic.

Also what is the 'generally accepted' air to air frequency within Europe? Google doesn't give any useful results.

RTL-SDR Discussion • Re: Advice Please. GNRadio, Osmocom Libraries, Straight Python?

Have you tried decode345 on GitHub? It seems to do most of what you ask. It is designed for Honeywell sensors, but would probably be adaptable to your needs. https://github.com/denglend/decode345

Stratux UAT radio not working

Total linux and Rpi noob...

Purchased a pair of stratux radios from amazon ( https://www.amazon.com/Stratux-1090ES-UAT-Radios-Antennas/dp/B07K1GZMM9 ) for a flightaware install on raspberry pi. Running stock piaware image. Went to serialize the two radios and the 1090 Mhz radio went fine. The 978 UAT radio is not detected by the pi, but red light flashes on it.

If I do rtl_test it shows the 1090 radio working and properly serialized. If I do lsusb with the UAT radio plugged in it says Bus 001 Device 011: ID 0403:7028 Future Technology Devices International, Ltd. I am thinking that the Pi doesn't have a driver for this chipset?
