Two recordings I made during the 2011 CQ WW CW contest showing how well the Butternut HF2V receives on the 21 and 28 MHz bands. The videos were recorded using the Funcube Dongle equipped with the HF converter kit and my GNU Radio based software defined radio receiver, GQRX.

Daily Gpredict builds for Ubuntu

Print PDF

Daily Gpredict builds for UbuntuThanks to Jan Simon, DL2ZXA, we now have daily builds of Gpredict for Ubuntu 10.04 - 12.04, both 32 and 64 bit. Jan's recipe fetches the code imported from SourceForge, merges it with the translations done in the Launchpad, then builds the packages and puts them in the Gpredict teams Daily builds PPA. You can use this PPA as you would use any other PPA; if you don't know how check out the instructions on the PPA page. Obviously, this is only recommended for testing and not for production use.

Logitech HD Webcam C920You may already know about my existing enthusiasm for Logitech webcams, which is due to the combination of relatively good image quality, high resolution and easy to use UVC interface. I was therefore very happy to learn about their newest camera, the HD Pro Webcam C920, which in addition to the standard HD webcam stuff we already know from the C910, also provides hardware encoded H.264 video stream!
