Re: V3 and Bias T

Like I said before, I don't really know what I'm doing but... Doing this made the original instructions work: echo -e 'blacklist rtl2832\nblacklist dvb_usb_rtl28xxu\nblacklist rtl8192cu\nblacklist rtl8xxxu\n' | sudo tee /etc/modprobe.d/blacklist-rtl-sdr2.conf sudo reboot I still want to know the per...

To have the bias tee permanently on, replace the drivers with the rtl-sdr-blog version.
What commands do I use to do this? I have tried a few things but have to idea what I'm doing.
I'm starting with a piaware image and wiedehopf graphs.

Re: V3 and Bias T

My RPi is now running two receivers, the V3 and a Smartee, to monitor 1090 and 978 on Flightaware. I can't make the V3 software mods turn on the bias-t and want to know how to modify it ON permanently.

Re: V3 and Bias T

I'm not positive that your instructions are what made it work. There was one other thing I tried and didn't verify first. I initially got it going by manual commands. Stopped dump1090: sudo service dump1090-fa stop Then sent your bias t command And a restart of dump1090: sudo systemctl restart dump1...

Re: V3 and Bias T

Thanks, it's working now. Yesterday afternoon, after the bias t was activated I connected the LNA directly to the dongle in my shack. That doubled my positions reported to Flightaware in the 150-200 range. So far today it is 4x as many in that range. I just came in from mounting the LNA directly to ...

Re: V3 and Bias T

I'm using the package from ADSBreceiver.net with piaware in it.

I guess a better question is how to turn on the biast before the other stuff loads. I thought I have seen that somewhere but could not find it again.

V3 and Bias T

I'm trying to use the RTL-SDR V3 dongle on a RPi for ADSB. Swapping the V3 for the Flightstick pro works but when I try to activate the bias t for the new LNA I get this error: "usb_claim_interface error -6" I went through the setup steps multiple times and searched the net for help but have not fou...

Re: Cable for LNA question

All of my equipment is less than 2 years old and the connectors are out of the weather. As far as I know it's all in perfect shape. I have done a lot of experimenting in the past year trying to find a better setup without getting too expensive. I thought connecting the dongle directly to the antenna...

Cable for LNA question

My current adsb setup is RPi-FA Orange SDR-40ft of RG6-FA 49 inch 9db antenna 35 feet up on a tower. I am planning to substitute the RTL-SDR V3 and add the new RTL-STR LNA. My main question is with such a powerful LNA, would upgrading the cable from the RG6 to LMR-400 or LMR-600 really make much of ...
