A technical question...

First, let me preface this with, this is not important. I'm moving next month and the issue will be moot. This is just a matter of curiosity.

Can a baby monitor interfere with digital tv broadcasts?

My neighbor just had a baby. two days before the baby was to come home, and two days before the digital cut over, my reception in general went to shit. I still can't receive the digital broadcast of CW11 (missing out on Supernatural reruns).

The family is from India and they do go back to India on occasion. I only mention this because we don't know if any baby monitoring equipment they might have was purchased here or over seas.

So, if they got a baby monitor, could it be interfering with my TV reception?

I've never heard of it messing with TVs. The newer ones have a tendency to clash with 2.4GHz cordless phones, but usually it would be in the direction of the baby monitor picking up phone conversations and neighbors baby cries, not the phone itself getting messed up.

I've seen Ghostbuster's II! It's not a baby, it's never just a baby. It's a a baby possessed by the evil spirit of Vigo the Destroyer of Worlds (and tv reception). They might look innocent, but you can never be too careful. ;)

Any electrical device (even a toothbrush or toaster!), especially one that broadcasts or receives signal - can interfere with the broadcasting or reception of any other signal.

Most electronics detail that fact in their fine print.

FCC regulations strive to minimize or prevent that from happening, though it still can and often does. Equipment manufactured for use in other countries and not specifically designed for use in the USA has a higher likelihood of causing interference.

TYhat brings up one other question I've had for a while. The FCC requires that all electronics accept outside signals. Or at leas they used. I'm assuming it's so you can stop/jam/disrupt a device if needed, but damn.... I wish things were better sheilded so I could have my cell phone near things with speakers and not get that annoying noise.

Anyway, anyone know the real reason all electronics must accept outside signals?

I think the long short of it is the fact that if a devices is shielded against accepting signals, it is essentially considered a stealth/spy/terrorist device.
