Hi Walt,
I can confirm your antipode DX experience(s). I use my qth in Eastern Thailand a couple of months per year. The calculated antipode location of my qth is close to Lima, Peru. I discovered:
1. daily window to 60 mB Peruvians around 1100/2300 UT year round, best in Feb./March.
2. The maximum lasts up to 30 minutes with extraordinary signal level.
3. Still unclear: The diameter of this antipode spot, I expect not more than 300-500 km.
4. Seems to work excellent on 60m, tried mediumwave without success so far. As Wolfgang mentioned the couple New Zealand <--> Central/Western Europe has been observed often. The antipode location of most of "us" is in the middle of nowhere, where is no AM tx. Example Radio Quillabamba 5025 kHz, rec. in THL, Perseus SDR + EWE:
