over 100 miles".
If you feel that ground wave contact on a clear, quiet morning is impossible with 1700 watts between an antenna at 100 feet and an 8 element directional yagi at 70 feet located 200 miles away, that's simply an uneducated opinion. Look at the math:
When factoring the limits of the horizon one must consider the following: My station is 470' above sea level
(
source) with the antenna an additional 100', totaling 570' above sea level. Online research reveals that Fowler IN is 820' above sea level (
source) and the other station indicated his tower was 70' tall, totaling 890' above sea level.
At these heights, the horizon would not come into play over a mere 200 mile distance. Over 200 miles the earth's curvature is approximately 670' (The earth's curvature is about 16.75' every 5 miles, 16.75 x 40 [5 miles x 40 = 200 miles) = 670'). This puts the two stations within line of sight and above the earth's curvature at 200 miles.
I'm not here to argue about it, if you still don't believe it's possible then you're entitled to your opinion and I'll respect it without a problem.

After climbing the tower and strapping myself to the top with a climbers harness, I lowered the Imax2k on a lightweight rope to a friend on the ground. The Imax was untied and the rope attached to the I-10k to be pulled up the tower. The hardest part was standing it up and sliding it onto the mast.
I've never been very afraid of heights and I've climbed the tower enough times to feel secure at the top, but I'll admit when the tower was first erected it took me a while to get past the 40' mark.
