Yet another Zenith roundie

What are you using as an antenna with that DTV converter? You mentioned you don't have cable or satellite, so the only way your set would work at all would be with a DTV converter box, and I'm sure you are some distance from Birmingham's TV towers so you would probably need some sort of outdoor antenna. I wasn't aware these boxes were even available anymore, as inexpensive as many flat screen TVs are these days (I see some sets with 20-inch-plus screens advertised in my Sunday paper for under $200), although you said yours was a 2009 model so you've probably owned it since the beginning of the DTV conversion.

Thanks, and yes, I'm aware of the convergence issue. I tried doing dynamic convergence using the coils on the convergence board, but they didn't do much of anything. I got it as good as I could and left it alone.

I got my Zenith converter box brand new in the box in January of this year at an estate sale. I'm using an Iron Butterfly antenna.

I think he means the classic UHF bowtie.

Yer bowtie ain't an Iron Butterfly till it has received at least the albums Heavy,
In-A-Gadda-Da-Vida, Ball, and Metamorphasis.

If you are using just a simple UHF bowtie antenna, you must not be as far from Birmingham's TV towers as I had originally thought. You are only about 9.5-10 miles from the city of Birmingham itself (I looked up the city on City-Data.com yesterday), but it is possible you could be slightly further away from the TV station towers, as most TV stations have their towers located in high-elevation areas, often high-ground suburbs, so as to maximize their coverage areas. As an example, the TV stations serving my area near Cleveland are located in Parma, Ohio, a southwestern high-elevation suburb of the city, some 40 miles from where I live. There are some areas, however, such as New York and Chicago, in which the TV transmitters and antennas are actually located in the downtown areas of those cities; New York's stations are atop the city's Empire State Building (some having been relocated since the World Trade Center disaster in 2001), and most of Chicago's stations are atop that city's Sears Tower.

BTW, I didn't realize you had already reconverged your TV's CRT. It's been a while (45 years, to be exact) since the last time I had a TV with a round color tube, but I do recall that it isn't easy to converge them, especially in the corners of the screen. (I was trying to converge my set's tube by eye, without a pattern generator--believe me, I'll never do that again, as the results were far from even optimal.)

Huh? A roundie does not have "corners of the screen"...

Those durned manufacturers. Always cutting corners...

LOL
No we know why they made roundies !

That is what makes the corners hard to adjust! You can't see them so your converging blind.

I stand corrected. I meant to say I could not get decent convergence over every part of the round screen, although that may well have been because I was trying to converge the tube by eye instead of using a generator.
