Default NVIS and VHF?

That's quite a drive. Thanks for the numbers. I've ignored the
antenna heights as they don't seem to make much difference. 31 km (19
mile) path length. The K7JEP repeater seems to be on a wide flat part
of a hilltop. Pointing downward, it may not clear the edge of the
flat part if the antenna isn't high enough. Difficult to tell without
photos or numbers. Not much you can do at your end to fix that. Any
chance you have a photo of the K7JEP repeater antenna location?

Otherwise, the path is line-o-sight, and should be quite usable with
your American Legion J-Pole. Of course, a yagi would be better, but I
think tinkering with your J-pole, coax, connectors, and radio may be a
better solution (assuming the repeater is working properly).
