digital television’s dirty little secret

My daughter gave me eyetv as a Christmas gift. It allows me to view television broadcasts on my Mac.

It works great. My only complaint is that right after I got it, they came out with a version that also allows you to listen to FM radio broadcasts on a Mac.

Anyway, I connected the eyetv to my 25-element log periodic antenna, which is at the top of the tower, about 1000 ft ASL.

eyetv receives both analog and digital television broadcasts and that capability soon revealed to me the dirty little secret about digital television. The quality of digital television video is much better than analog television video, however, in order to view digital television video, the signal at your receiver must be stronger than the signal strength required to view analog television video.

Today, I can receive the analog television broadcasts of New York City channels 2, 4, 5, 7, 9, 11, and 13 with my eyetv and log periodic antenna, but I cannot receive any digital television broadcasts from New York City. So, when they finally shut down analog television broadcasts, I lose New York City. Similarly, I will lose other distant television stations once digital becomes the only television broadcast mode.

Is digital television a technological advancement? Not in my book.
