RCA 721TS Help

Nice, but a little odd. The image should be rectangular - not fill the screen. Something more like this. I wonder if the yoke is not pushed all the way forward or the HV is too low ?

Wouldn't that cause a neck shadow?

What kind of signal source is used? With my Zenith DTV convertor, I can get a small squared screen on some channels. With the caption, "set by program".

Over the air low power NTSC. We still have LPTV channel 6 in Chicago.

The darkness around mine is because I haven't perfectly adjusted the yoke and focus coil. I will do that when I get it ready to finally put back in the case. Getting the adjustable mounts at the proper depths will also help the centering.

Got it all back together....time to watch tv!

I can only hear the audio from them here. Decently I might add, but even on a huge TV Beam aimed at Chicago I can't see their picture.

A couple times when conditions were exceptional and beyond good conditions for FM propagation, back in the Q87 days, I picked them up in Fon Du Lac Wisconsin, and kept a mostly stable signal all the way back to Lake Geneva.

Was pretty cool.
