Finally receiving NOAA

Hey guys,

the other day I had opened a post cause my reception was suffering high RFI.

I now finally have resolved the issue. It turned out that the poles (V-dipole) were made of the wrong material, or were not 'pure' enough. Yesterday I have replaced the poles for new aluminium ones et voila, it works... with an LNA though.

I still have to figure out how I can reduce the noise in the image. Might have to move it left or right on the roof of the house, or raise it to a higher level, as at the moment it's right behind an aluminium chimney.

Probably later I'll try to go for a DCA, and then again later for a QFH antenna. Just to build up my experience and see the differences for myself.

KerberosSDR • Re: Booting up the KerberosSDR with RPi 3B+

On the KerberosSDR image, the software is already installed, there is no need to install the software again.

The HDMI should work, I have tested it on two HDMI monitors. Can I know the specs of your monitor? I've heard of at least one other person that the HDMI output is not working for, so it might be a bug.

Otherwise you can connect to the desktop GUI via VNC using the details on the guide.

KerberosSDR • Booting up the KerberosSDR with RPi 3B+

Apologies for my naive question. I was able to successfully flash the .img file to an SD card which is now in my RPi. Additionally I am able to connect to the WiFi hotspot and use the web browser to see all the settings of the KerberosSDR.

The one thing I am wondering though is I noticed my RPi does not display anything on my monitor. I’m assuming this happens for everyone using an RPi since noobs isn’t installed on the SD card? If this is the case how do I install the drivers and software etc mentioned in the beginning of the QuickStart guide while still keeping the same SD card, with the Kerberos image, loaded on the Pi?

Converting Raw I/Q data to GNU Radio (32-bit) format

Hi, I am working on a python script to allow me to convert the 8-bit interleaved samples from my RTL SDR to a format compatible with GQRX. I have performed what I believe are the necessary conversions (127.4 offset, and divide value by 128.0), but each time I try to read the file produced by my script in GQRX all I get is static. I would appreciate any pointers someone who has worked with pyrtlsdr before could offer. Thanks!
