Take heart, it may take a long time, but the plasma is steadily losing 
market share and the shortcomings of LCDs are being rapidly overcome to 
the point where they are far more popular than the plasma.

Plasmas are much heavier, take more power, and depending on who you talk 
to, have a shorter life than LCDs, particularly the new LCDs that use an 
LED light source.  Of course the light sources can be replaced in LCDs 
but not in the Plasma.

Here too I have noises I've yet to explain, or find, but in general HF 
is pretty good and I've had only a few noise problems on 75 and 40 this 
winter and I'm not so sure they were even in the neighborhood.

73 and good luck
happy New Year,
