Yes I have an old square TV with a converter box. The transmission is rectangular so the ends are cut off .When the USA upgraded all the broadcast stations to digital it was a horrific mess. If you didn't have a new TV you had to get a converter box. The channel signals are easily disrupted by weather, wind (trees moving?) and then the programs become pixilated and unwatchable.
Lots of progress there.
But... IT'S FREE!
Used to be if the picture was fuzzy you still could hear it. Now with the new and improved, when the signal is iffy I get nothing
They are coming out with another nexgen and we will need a different converter box....or a TV with that tuner
