Is there a way to use google earth or other mapping program to show lines of latitude or longitude?
At any rate, it appears my best reception for Chicago is really 166 Degrees and Milwaukee 355, just as TV Fool predicts.
One thing I was trying was to focus south on WRME, but even though the WRME coverage map shows me in range, it won't come in at all. I found that interesting..

Hi, Bob:
I think your neighbor might be a little jealous of your efforts. I hope he is taking into consideration the magnetic declination of 4 degrees. The Google map is oriented so that the top is True North. I added a grid to the satellite view and it looks square to me. The final authority would be a USGS topographic map of your area that might be at your local library.
I think the argument is unimportant because you are going to aim your antenna for best reception, no matter what azimuth it is. Signals are often skewed and can come in at the "wrong" azimuth.
As long as your rotator can repeat the same direction for you, that's all you need.

WRME is on real channel 6, which is a VHF-Low channel. What antenna were you using, the MCM 30-2476 or the Radio Shack VU-210XR?
Also, if you are using an FM filter, it might be taking out part of channel 6.
