Subject: LF: Re: Carriers

I can strongly confirm such QRM from modern TV sets. That also seems to be
the reason why some days I "don't have ears" when operation from DF0WD.  <<<<<<<  
 
Also confirm the range of these nasty carriers: they can indeed exceed the
range of 100 yards (~meters). The clubstation DF0WD is about 150mtrs away
from the next house, but a part of QRM seems to correlate with the TV prime
time. On the waterfall its impressive to see a group of carriers disappearing
instantly after the main evening news at 20:15 local.

I guess most of the QRM travels over the mains supply lines >>>>>>>>>>>>>>>>>> 
 
 
Today I purchased & installed a new Panasonic  TX-25 CK1  TV  receiver to replace an older one of same make.
To my horror, I found that it radiates a strong rough carrier on 136.1 spreading both up and down several hundred hertz making the band inoperable on all three of my antennas.
I have no doubt that, with difficulty, I will be able to return it to the dealers.
My problem is, what do I replace it with.  Has anyone recently installed a modern TV that does not cause QRM on 136 ? It would seem like "self mutilation" (Selbst-Verstuemmelung) to retain this equipment, particularly at present here in the UK with the awful junk generally being offered to us on tv.
Any suggestions would be greatly appreciated !
