Comment on Receiving Es’Hail-2 DVB-S2 on Ubuntu With LeanDVB by Adrian

I am struggling to install, have a new desktop install or ubuntu 18.04 and when i am following instructions and use make I get errors of:
libX11 not found. Will not support –gui.
libiio not found. Will not build leaniio{rx,tx}.
I have checked that I have libx11-6 installed and I also have libiio-utils installs but I am not sure what else i could be missing.
Anyone help please?

Meteor Reception Question, i get black bars at nearly the same spots in every meteor pass i receive, any ideas why this would happen ? The bars are typically the same size between images. The image below is one such image with the bars.

KerberosSDR • Re: Single radio failure on my KSDR?

Thank you for your reply!

I bought two so I am still able to continue my project.

I have given the DIP switches a couple of toggles. I don't think this is the problem because the DIP switch for the first radio correctly toggles the blue LED for that radio.

I don't really have the knowledge to locate the exact component that has failed. I will try wiggling and see if the light flickers.

If it still does not work next week, I will email as advised. Thanks again!

Troubleshooting Help • Re: Orbitron and Schedular Plugin — can’t track multiple satellites

Did you find a solution to this. I have the exact same issues. With the same satellites.

What was the problem?


Thanks

Ahhh here's something - I get a " library error -5" right after I hit enter for the 4th rtl_test
And each tuner runs fine individually right? If so, that seems to confirm that it's a power issue. The final tuner activating causes them all to crash because the power draw becomes too high for your supply.

I don't think you mentioned it before, but what type of power supplies are you using for the Pi3 and KerberosSDR?

Funny to see the conspirists / fidiots in the comments too.

Raspberry Pi: multiple NFMs with one dongle

Hi! I've just bought a Raspberry Pi 3 B+ to replace an older system whose Windows install crapped out and couldn't be easily fixed. This system had a single job: using a dongle to monitor 4 NOAA Weather Radio stations in my area (on 162.400, 162.425, 162.525 and 162.550 MHz using NFM), and feed them to A. an Icecast server and B. a SAGE ENDEC EAS box I bought off eBay.

On Windows, SDR Console worked great for this, with its support for multiple simultaneous frequencies. But I can't seem to figure out a workable solution to replicate this functionality on Raspbian. I've tried multifm and rtl_airband so far...I can't find very much documentation to even try to get multifm to work, and while rtl_airband sort of works, the USB sound card I bought has so many channels it makes PulseAudio flip out, and I'd really rather use JACK instead anyway to make it easier to route everything...

I consider myself competent enough to be dangerous, but I'm at my absolute wits' end here. Any help would be greatly appreciated!

Measuring the SWR of FPV antennas with an RTL-SDR

GOES 16 advice?

I set out on a project to capture and decode GOES-16 HRIT data. I got the 2.4 GHz 24DBI gain wifi grid antenna, and used a 3D printed spacer on the reflector to modify it for 1.6GHz. My dish's feedhorn came with a little arrow on the head pointing up/down, and due to the amazing chinglish instructions, I have no clue how to orient it. Currently this arrow points down, towards earth, the reflector bars being parallel with the bars of the dish. Advice on how the feedhorn aught to be oriented?

I've tried to the best of my ability to aim the dish with an actual compass, and a level/protractor, and somehow I think it's still not great. Advice on aiming?

I've got a Type-N to SMA adapter going from the dish, to my GOES sawbird filter/lna, which is mounted near to the antenna and powered via Bias-tee over the cable run. I have the sawbird outputting the signal through an SMA to Type-F, then down my cable run of RG6-quad to another Type-F to SMA adapter, then to my RTL-SDR. I have no FM bandstop or ferrites on the cable, as I assume the rfi from local FM broadcast stations resides too low in frequency to severely interfere with my signal.

All-in-all, I can't see any semblance of a signal in SDR# nor any VIT under 2200.. What am I doing wrong?
