You ever heard of a Blu-ray player with an infrared remote interfering with a satellite receiver with a UHF remote? Me either.
I was lead instructor and the Navy's point man for Electromagnetic Compatibility and everything in my mind is screaming THIS CAN'T HAPPEN! But it did.
We changed out the remotes, the satellite receiver, and then put in a whole new system. Dish technicians, engineers and I were all pulling our hair out. And the culprit was - in fact - the Blu-ray player above it. We relocated the satellite remote antenna with a makeshift extension cable and all is fine.
Just goes to show that electronics is NOT an exact science: trons are going to do what trons are going to do.
Hope everyone's Labor Day weekend is going swell!
