Now you're ruining my false view of the world. It's not any fun when you have to look at the facts. smile

As an avid long-range radio listener (shortwave, etc), I think that plasma TVs should be banned from the face of the earth - unless they figure out a way to filter out their unprecedented amounts of RFI. In comparison, LCD TVs emit very little noise.

I don't know how plasma TVs were ever allowed to pass FCC/DOC RFI suppression standards. I hope that none ever show up in my neighbourhood or my radio hobby will be largely over...

I remember when it was the other way around and YOU guys were effing with MY TV signal. OK, it was black and white kinescope, but I still remember.

Always call the place you live a house. When you're old, everyone else will call it a home.

Not me. I'm just a listener not a transmitter. IOW, I'm not a HAM. From what I understand, modern TXing gear does not cause the interference problems that the older stuff did years ago.

RFI is becoming a huge problem universally since our government regulators stopped doing their job of policing the electronic equipment that is being imported by the ton daily. On my daily walks around our small town here with my miniature Sony radio, RFI is absolutely brutal when passing certain businesses. Thirty years ago, the authorities would have hunted down the emitters & rectified the problem - not anymore.

Switching power supplies (wall-warts) are a major culprit because they are made so cheaply without proper filtering & also because they are everywhere in our lives & homes.

It just so happens that plasma TV technology is really bad for emitting really strong RFI some reason...

Wow, you learn something new everyday. I surely did not know that about the plasma TVs Tom, I promise I'll keep our Panny south of the Mason-Dixon line and hopefully out of radio interference range of any radios close by.

Peace my blues loving brother!

Rick:

I think that I'm safe from you, ha! Enjoy your plasma.

I don't want to hijack this thread with RFI stuff; however, a couple of years ago I had an interesting experience with RFI in my radio room. I installed a D-Link Wireless Router that was situated close to my radios because my computer & cable feed are there also. When I fired it up, I got big interference on the Shortwave band.

I complained to D-Link Canada & initially they were of no help; however, I guess that my complaint finally made it to their techies in Toronto & eventually to their engineering staff in Taiwan.

The next thing I know, I have 2 engineers flying overnight from Taiwan plus 1 from Toronto to check out my complaint in my house. I couldn't believe it!

With my radio on when I plugged in the router, they winced when the noise started. The chief engineer brought a bag of power supplies & we spent some time experimenting with them. All of his modified power supplies with installed filter caps worked just fine. He left me a couple & away they went back to Vancouver & all flew back home that night. I wonder what those 3 trips cost D-LINK, especially considering that the router cost me only $50? I kinda have a soft spot for D-LINK products ever since.

If all power supplies were built that way, and it wouldn't take much effort nor cost, the world would be a quieter place RFI-wise...

That's actually a pretty cool story.

Sorry about my plasma(s) generating RFI but their price/performance can't be matched by LCD!

I don't know. Looking at a wall of HD TVs at Best Buy or Future Shop, I don't see a whole lot of difference in display types nor brands, except perhaps how they are set up. Showing HD material, to me they are all 'similarly good'.

I'm still using a 50" Sony XBR rear projection LCD from 2003 - now on its second bulb. That technology did not give the best blacks but normal daylight type scenes are stunning to my eye & still very satisfying. At the exorbitant price that I paid, I'm going to run it till it blows up & then it will probably be an LED/LCD.
