I've been running some tests on my 8 circle array with K1JB. Joe is 17

What frequency are you at and what time of day?
It's entirely possible to get skywave. At some frequency, vertical
incidence reflects straight back down.
You might look for an ionosonde near you - these days, many ionosondes
put their plots online in near real time.
