Interference to Ham Radio from Plasma TV
This is typical of the interference from a high number of plasma TVs I have come across. The interference can often be heard from over half a mile away. It is probably the result of the manufacturers removal of key components to make the device cheaper as can be seen by examining the circuit boards. There are makes and models out there that do not cause interference but they are out numbered by those that do. I would not buy plasma as I think LED TVs are better all-round. Radio amateurs can avoid buying one in the first place but if a neighbour buys one then it can be a hell of a job getting it resolved. It is time the manufacturers owned up and OFCOM got out and enforced their own rules.

I honestly believe that the short wave hobby is doomed, especially in the UK. Radio amateurs are a small minority that contribute nothing to the regulation and enforcement process; enforcement costs money which is going to be even tighter in the current economic climate; OFCOM is in the pockets of the manufacturers who will resist anything that eats into their profits. Need I say more?
ReplyDeleteI hope g4ilo is wrong, but sad he may be right.
ReplyDeleteI have terrible interference from plasma tv's and PLT devices. It is now impossible to use the HF bands for most of the day at this location. If my amateur gear created that level of interference on Emerdale or Coranation Street Ofcom would come down on me like a ton of bricks. Unfortunately they seem to be in the pocket of the trash broadcasters.
