I'm in Melbourne Australia, and my PC seems to be causing a large amount of interference on all of the nine networks digital TV stations (and possibly others to a lesser extent).
it effects both the main TV, and also my USB TV tuner.
Here is my PC spec:
Intel Core i7 4790K 4.0GHz (4.4GHz Turbo) Quad Core
Be Quiet! Dark Rock 3 CPU Cooler
MSI Z97-GUARD-PRO Motherboard
Be Quiet! Pure Power L8 600W Power Supply
Deepcool Tesseract SW USB 3.0 Mid Tower Chassis Black/BlueCorsair Vengeance Red CMZ16GX3M4X1866C9R 16GB (4x4GB) DDR3
Samsung 850 EVO Series 500GB M.2 SSD (M.2)
Seagate Barracuda 2TB ST2000DM001
Gigabyte GeForce GTX 970 G1 Gaming 4GB
Pioneer BDR-209DBKS 16x Blu-Ray Writer Black
Microsoft Wired Desktop Keyboard 600
ASUS PB278QR 27in Widescreen IPS 2560 x 1440 Monitor with cables and speakers
ICY BOX 5.25in Multiport Panel with Card ReaderTP-Link TL-WDN4800 450Mbps Wireless N PCIe Adaptor (802.11a/b/g/n)
Targus Bluetooth 4.0 USB Adapter
Note, the side of the PC case has a transparent window (I don't know if that is relevant), I have tried covering it with foil, and grounding it. It completely obliterated CH9 reception!
Sometimes the position of where I am standing near the PC can improve the reception.
If i connect the audio output of the motherboard, to the front panel audio jacks (see icy box above), and then plug in the headphones, this greatly degrades CH9 reception even further. However, if i connect it to the case's inbuilt audio out jacks at the top, and then plugin headphones, the interference is not increased as much.
I'm not sure what is going on here, or how to solve it. Ideally, the reception should work without, and with headphones, and regardless of socket used.
so in short:
- PC: interference
- PC with foil: massive interference
- PC with front headphones connected: a lot of interference
- PC with top headphones plugged in: a bit more interference then no headphones
- PC with person standing in the right position nearby: interference reduced
- PC off: reception is fine.
It changes from day to day, and even time of day, and seems to have nothing to do with how loaded the PC is, even while idle the effect is the same.
