Using the Omnia SDR with Quisk on Linux

Now that I finished my Omnia SDR for the 60, 40, 30 and 20 meter bands, I started looking into how I could use it on Linux. I remembered reading some emails on the project mailing list about using Quisk, which is a mature SDR transceiver application written by James Ahlstrom, N2ADR. I decided to give it a try.

Using the UT-100 DVB-T modulator on Linux

In October last year I learned about the UT-100 series of DVB-T modulators available from a company in Taiwan. At that time I have already been working with software defined video broadcasting; however, I still found the idea of a small USB-stick modulator very appealing for use with embedded devices. In this post I have collected my notes about setting up and testing the UT-100 modulator on Linux.

Cubieboard as Funcube-1 telemetry receiver

Following up on my not too successful first contact with the Cubieboard, I have decided to try it one more time. It has been annoying me to have a computer board lying on the shelf not doing anything and since I wanted to migrate my Linux-based Funcube telemetry decoder from a PC to a single board computer this was an excellent opportunity / excuse to try the Cubieboard again.

First contact with the Cubieboard

I got myself a Cubieboard some months ago, not because I needed one by because I had the opportunity to join a group purchase organized by some friends back then. I wasn’t looking for a new board, however, the Cubieboard looked interesting because of the onboard SATA connector. Plus the analog audio input / output on the board may also prove useful for SDR and digital voice experiments.

RTL-SDR spectrum analyzer on the Beaglebone

Take a Beaglebone, add an LCD cape and a £10 USB TV dongle, install librtlsdr and my rtlizer software and you have an awesome hand-held, real-time spectrum analyzer.

The Funcube Dongle Pro and Pro+ on the Raspberry Pi

Although I have had a Raspberry Pi rev B for several weeks now, it wasn’t until last night that I got a chance to try it out. Since several people have reported failed attempts at getting the Funcube Dongle Pro and Pro+ play nicely with the Raspberry Pi, I decided to take it as far as I could in those few hours. The result is this very brief tech note about how to make the Funcube Dongle Pro and Pro+ work on the Raspberry Pi.

NOAA APT reception with Gqrx and rtlsdr

About a year ago I posted a step-by-step guide about how to receive NOAA APT weather satellite images using Gqrx SDR and the Funcube Dongle. Today, I tried to repeat the procedure using my ezcap eztv666 rtlsdr dongle with very good results.

Turning the Beaglebone into a high definition IP camera

Few weeks ago I posted some notes about using the Logitech HD Pro Webcam C920 with Gstreamer. I have since ported the setup to the Beaglebone, effectively turning my Beaglebone into a streaming IP camera that can deliver constant bitrate H.264 video at full 1920x1080p30 resolution without breaking a sweat.
