I have blogged about the interference from a local Panasonic Plasma TV before, the TV a TH42 PX80B disrupts my operation on frequencies from LF to VHF. I was late identifying the culprit as I thought it was some other 24/7 interference source, not a domestic device.
The only solution for me has been to abandon the worse effected bands, however recently I wanted to try the 136kHz band again, noting the owners leaving on Sunday I installed my Loop antenna outside and saw a clean band.
Yesterday the interference was back, it was still there at midnight when I turned off my RX, at 06:00 this morning it was there again when I switched on. Panasonic should never have been allowed to market TV’s that clearly radiate over and above the specified agreed levels. I told Panasonic so, their plasma TV’s are notorious, I also told them that I would describe illustrate and publicise the problem as and when. I had many Panasonic devices in my household, recently when replacing my domestic TV, as I promised them, I changed my brand.
Here is the 136kHz band at my location with the Panasonic on.
Despite the interference, stations can look at my Grabber and see the clear slots, amazingly as propagation was good last night I copied Stations in the UK and Germany between the interference lines.
The levels of radiation from the Panasonic TH42 PX80B can surely not be healthy, society allows the flouting of regulations by big corporations. Unfortunately the reason for this TV and many others being on at 06:00 or earlier is because modern parents consider it OK to put a dummy in the mouth of babies and young children and sit them in front of a TV on the Cartoon Channel for hours on end whilst they get on with their lives. I hope the kids don’t suffer any consequences from being reared on junk.
For those who are not used to seeing wide spectrum displays without interference here is, an often rare, occasion when the Cartoons were obviously just not good enough and the TV was off.
