Channel 4 London got available free to air via sattelite. But some days the sound is missing. First I thought it was a hardware malfunction at the uplink station, because sunday morning it came back, got perhaps repaired. But now the sound at 10727 MHz vertical, 22000Ks/s, video 2335, audio 2336 and PCR 2310 is missing again. What's matter - something intentionally? with greetings from Germany
