| 369082 | 2005-07-03 15:48:00 | PC creats interferences for one of TV programs for TV's in the building. Is there a way to supress ? Thanks |

| 369083 | 2005-07-03 16:57:00 | Yes there is I beleive but first you'll have to tell me if you're using a modem, any other kind of electronic equipment on your PC. Where is the PC located? Near the TV? If so, try moving it to a different spot. | LIONWOODS (8468) | ||
| 369084 | 2005-07-03 17:23:00 | I found that my modded case with the clear window on the side (for all the pretty blue lights inside to show) lets rf out of the tower . It kills my tv (US channels 2,4,7 only; the rest of them 5,9,11,13 and all the uhf are ok) Since I was used to having certain channels get hashed from CB radios, I knew it was an rf thing, especially with the selective channel distortion too . . I added grounded taps on the coax outside at the antenna base where the coax is closest to the building, and at each splitter for all the tv's in the house (6) . I got rid of MOST of the rf interference, but not all . I ran individual ground wires to a 12 foot copper coated anode that I drove into the ground at the north side of my house (the shady side) as I figured that area would stay the dampest for good ground effects/drain . Not 100%, but a lot better . Unfortunatly, the main coax from the antenna runs right thru the wall immediately to my right side here at the computer, so I imagine I am broadcasting a heavy signal right into the coax anyway . I don't know about NZ, but if you are using the 300 ohm stuff )that looks like a flat ribbon), then all bets are off for fixing it as there is no shielded sheath on it for protection . :2cents: |

| 369085 | 2005-07-03 19:45:00 | Computers are a very nasty source of RF interference, the only way to successfully overcome it is to make sure that you have a good signal for the TV from a correctly installed outside aerial system. Even then, if you live in a marginal TV signal area its a problem. It's also a problem for your neighbours, I have seen cases where the MED Radio Inspectors have had to track down offenders as they were ruining TV (and Radio) reception for a cluster of people. Clear panel cases (as Joe correctly points out) are a no-no, they destroy all attempts that case builders originally employ for keeping the signal in. One of the reasons you don't see any OEM computers on the market in all - acrylic cases is that in most countries its illegal, as it breaches the regulations for radiated interference. Selling the cases after-market is a grey area though. |

| 369086 | 2005-07-04 00:31:00 | I was not using modem, but the signal of one of the channels is weak. Thanks, thatis it, I recon. |

| 369087 | 2005-07-04 02:00:00 | fix the pc. the signal have to be extermly weak for a modern pc to interfere with it. even with boosters on the aerial system (which also boosts the interference) a pc shouldn't interfere. btw check the screen refresh rate, sometimes that causes interference. |
