I was surprised to see (or maybe not so surprised) that the combination of the KX3 and the KXPA100 was used in the Norfolk Island Dxpedition.
Propagation must be good - I worked VK9NT 8378 miles short path on a dipole at 500 watts on 12m. He was really faint,
I also worked Benin (Africa) - a mere 5600 miles - on 3 bands - 17m, 20m and 15m all on the hex.
I also worked Tristan de Cunha - all on the same evening on 30m. This has been one of the most productive DXing in quite some time - 5 band points. Thanks to Sunspot AR1528 for the ionizing radiation.
