Re: On-air tests of the Wimo TA-1 turnstile antenna

Why not ask the manufacturer or reseller for the assembly instructions? Anyway, as far as I recall, and it is a long time ago, the elements are mounted in alternating order long-short-long-short.

Re: Gqrx 2.2.0 released

Alexandru Csete — Tue, 19 Feb 2019 18:03:37 -0000

It is because your package manager is configured to "Install recommended software", which will include things like GNU Radio SDK that is not required by gqrx.

Take a look here https://github.com/csete/gq...

Gqrx for RPI3 binary package (including essential dependencies): 962 KB
Gqrx for 64 bit Intel (including dependencies except Qt): 4.28 MB
Gqrx AppImage (containing everything!): 59.8 MB

They are on github, please see the page called "GRC Examples"
Seriously guys, do you really expect these things to work after 8 years? GNU Radio has changed a lot!

Re: RTL-SDR spectrum analyzer on the Beaglebone

If you look in the source code repository, you will find instructions for the Raspberry Pi. The project is several years old and I have not maintained it, so it may not build out of the box.

Thanks for the info. I have added it to the list :)

Ok, sounds like the fedora package for rtlsdr does not set up the permissions correctly. In any case, either the gqrx mailing list or a fedora support forum would be a more appropriate place for these discussions. Commenting on this website was intended for discussions about the topics in the posts.

I recommend using the package that comes with fedora:

I suppose what you are really asking is whether my Mac OS X bundle includes support for the PlutoSDR. The answer to that is no, it does not. Sorry.

The cable comes from the top of antenna and out through the bottom of the pipe. I am not going to dismantle it into bits and pieces to check this, sorry.

Re: Gpredict on Android

Many embedded images got broken when I was forced to move site. I have now fixed them here, but please note that this is a 5 year old article and many things may have changed since then. I think now there are dedicated Android application that can do the job without installing linux.

Screenshots now fixed.

Glad to hear it works, thanks for letting me know!

Glenn, I'm glad to hear that you are using the Linux version. Phil is working on making it build for windows, but it will be difficult to make it run properly. I think Gpredict on Linux will always be more stable.

Please read the announcement above.

Re: My first weather satellite images with a 137 MHz turnstile antenna

Alexandru Csete — Wed, 25 Oct 2017 15:46:30 -0000

Why? I have no interference from broadcast transmitters. I can receive a cubesat that transmits with 50 mW using an omni-directional antenna.

Re: Streaming audio over UDP

Alexandru Csete — Thu, 28 Sep 2017 14:17:43 -0000

The hardcoded values are used as defaults for initialization. Seriously though, don't you see a button with "..." in the same row as the UDP button???

Re: Streaming audio over UDP

Alexandru Csete — Thu, 28 Sep 2017 07:55:08 -0000

Which instructions are no longer valid? Surely you are not referring to this article, which lists the default port 7355 on eight occasions ;-)

Anyway, the audio streaming options are accessed through the button with 3 dots on it, then select "Network". It is a one way stream so you can only configure the destination host and port.

Re: Meteor-M N2 LRPT downlink

Alexandru Csete — Sun, 24 Sep 2017 16:31:17 -0000

Hi Bob,

Thanks for the info. I do not yet have any setup to decode LRPT images from Meteor. There is some software around on the Internet, but I did not yet have a chance to check it out.

Re: Turn your Raspberry Pi into a live HDTV transmitter

Alexandru Csete — Fri, 05 May 2017 19:39:11 -0000

I don't remember exactly, but ffmpeg muxer introduces a significant latency (~5 seconds). I think this article is now quite obsolete and anyone interested in this topic should take a look at rpidatv (and avc2ts) instead: https://github.com/F5OEO/rp...

Hello Matthew,
I have added your scanner interface to the list, thanks!

Re: My first weather satellite images with a 137 MHz turnstile antenna

It's something I'm working on, but not yet available for download.

Hi Kevin,
I used wxtoimg for these images.

Re: NOAA APT reception with Gqrx and rtlsdr

Alexandru Csete — Thu, 06 Apr 2017 15:37:29 -0000

The connector on the arrow is a BNA male connector and the connector on the Funcube Dongle is an SMA female. So you will need a BNC female to SMA male adaptor.
