It sounds like you and I are both scratching our heads still.
Just to confirm,
Are you located in Massachusetts? Or are you in New Hampshire? The LAT/LON coordinates shown on both TVFR reports are for a location near an address in Concord, MA 01742 according to Google Maps.
When generating a TV Fool report, my preferred method is to open the
Interactive TV Maps tool. I leave the 'input method' set to the default, 'address'. Then I enter only the ZIP Code, and then click the 'Map This' button.
At this point I have a map displayed, with a movable cursor located at the center of the ZIP Code I entered. I then use my mouse to drag the cursor to the exact location I'm interested in. In the upper right corner of the map I can select from four view types, I find it helpful to have all four available... The Hybrid and Terrain modes seem to be what I use the most.
At the bottom of the map, I enter the antenna height, and can find the LAT/LON coordinates of the cursor (in decimal form, not deg/min/sec).
Once I have the cursor location and the antenna height set correctly, I click on the 'Make Radar Plot' button located at the upper right corner of the map. The TV Fool report opens in a new tab or window. I can then copy the URL from the address bar of my browser, for posting to a thread.
I hope this helps, I just want to be sure we give you advise based on the actual conditions at your location.
