Mast down, I cannot get my foot in so I'm always on my toes. When I come down off the tower my calves are screaming. :-) My prior alinement was a degree or two off. That came up with some interesting results.

All results have the PA on line. I might experiment tomorrow with it off line. Going through the DA to the SDT Ch 3 (24) was there, Ch 5 (16) went away, opposite of before. All others (8,10, 15, 45, 61) were there.

Now the starling results. Just for grins I checked out the LG TV. 3, 5, 8, 10, 15, 45, 61 were all there, AND SO WAS 12!!!! Barely but I never expected to see it. Trying to measure it is what drives me up a wall. The LG has a signal meter. Shows Strength and Quality. Through the DA S 54 Q 17-19; Direct from antenna S 54 Q 20-32; Splitter 3.5 leg S 54 Q 19-25; 7.0 leg S 54 Q 20-38. Q readings are always bouncing all over the place. S pretty much stayed at 54 occasionally going to 55 no matter how the signal was being provided. It would seem that the Q would drop when I went from the 3.5 leg to the 7 leg. I suppose it’s all atmospherics, not being able to test all at the same time.

The Hopper OTA Tuner there was no 3, 5, & 12. Then I tried a direct antenna feed to the SDT and both 3 and 5 were gone. I’ve gone back to my default going through the DA until the next round of tests. Any suggestions on what to try?

KPHO, virtual channel 5.1, is real channel 17, isn't? If you are going to use the virtual channel number, please use the decimal form to avoid confusion.

That's true; OTA signals are constantly changing.

Sounds like the LG has the best tuner.
