I didn't want to hijack acfleet's post but I have a question about over-the-air tv reception. At the farm I have a pretty good antenna with a signal booster mounted on the roof and a fairly new tv (made after the gubmint mandated going to a digital signal). Sometimes I can get stations from as far as 75 miles away and sometimes I can't get those that are 50 or less miles away. Ft. Gordon (now called Ft. Eisenhower to be politically correct) is between the 50 mile stations and my antenna although not in a direct line. I can be sitting there watching the so-called news early morning or at night and the reception just goes to crap. Ft. Gordon handles some of the cyber warfare training and I suspect that might be the culprit.

We get pretty good reception here but like you said some days you lose a few channels and once in a while you lose a bunch.

With the Solar Maximum coming on may see quite a bit of issues for a short few years.

A very fond memory is when we'd have to go turn the antenna so pawpaw could watch Matlock.

I think the solar thing is messin up everything now and will continue til it runs its cycle. Our internet went to hell this summer!

So yes, we're amidst Solar Cycle #25.  The weather that's being screamed about by empty-heads is the direct result of solar activity from just a few weeks ago.

This cycle is already looking pretty energetic, and it looks like it'll last a little longer.

Solar storms have a variety of interesting phenomena to radio.  Enhancement is what happens when solar energy alters the troposphere (think sky... clouds low and high) and the magnetosphere (the earth's magnetic field).

SOME circumstances cause SOME frequency ranges to reflect between earth and sky, bouncing their way around the globe.

SOME circumstances cause SOME frequency ranges to get absorbed.  Sometimes, the enhancement is so great, that noise (both from man made sources, and natural sources) becomes so great, that the signal you WANT to hear, is swamped by noise.

Sometimes, enhancement bounces the signal right over your head. 

If you're an AM radio listener, you'll notice that during the night, your signal is different from during the day.... that's the action of the sun, doing just as noted above.  It occurs naturally ALL the time, but during the peaks of the sunspot cycle, it is downright extreme.  To combat this variation, radio stations are often granted license to run higher power, and/or directional antennas to reach their coverage area during the day, then dial it back at night.

Radio engineers have, for almost a hundred years now, understood the presence of, and the acting character of our solar cycles... in many ways, they understand solar cycles better than most meteorologists... alas, there's an overwhelming number of loud voices that know very little, but spout much falsehood.

For decades, analog television managed through solar cycles and the propogation variables that followed.  Your TV signal problems now, are a result of executive actions that forced this 'modern digital' upon us without significant understanding of the physics involved, and the result is loss of robustness and reliability.

YEP, it been that way ever since the switch to digitally transmitted TV signals. Sometimes I only loose a group of pixels, other times the image just freezes. That's progress. Kinda like having a computer controlled vehicle that dies on you with no way to limp it home like you could on something before computers controlled everything on a car including the door locks. Unfortunately as for the TV signal, that's the way it is and we have to live with it. As for computer controlled vehicles, I will never have one.
