There is much more to electronics and RF noise than, TV is 8ft away. These transduces are very sensitive, and sometimes nothing for some, but alot for others. So unless you have a spectrum analyzer or at least an oscilloscope, only way to tell if its a problem is to buy one.
What I can tell you is that when checked with my check weights,my scale is always exactly on calibration.If I bump the table or scale when loading,and throw off the zero,the zero will read + or -.It is easily rezeroed by pressing the zero button.With my 10-10,it could still be bumped off zero,and took longer to rezero.
But still bet I can beat you in trickling a powder charge
with a beam.
It's too bad that you are so far away,as I would enjoy taking you up on that bet.Since switching to the digital,my reloading time has been reduced significantly.
