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.
