This gave me the idea to re-run scan with different frequency files and different antennas. It turns out that my problem is the antenna. I was using the antenna I have been using with my previous card, which is an internal DVB-T antenna with amplification (external power supply.) I get zero signal with that. But using the Terratec-provided cheap "stick" antenna, I get signal again, with reasonable quality (although not as stable as with the old card and the powered antenna.) I also get signal (but not all channels) with my original antenna _unpowered_ (thus signal not amplified.) I admit I don't quite understand. I would understand that a bad, unpowered antenna causes no signal to be sensed. But how is it possible that a supposedly better, powered antenna causes that kind of issue? Oliver, out of curiosity, what antenna are you using? The Terratec-provided one, or another one? -- Jean Delvare
