Bruce, you are confusing miles with kilometers. KTXT is 2030 kilometers...but 1260 miles from Orlando.
Stephen (Pianoplayer) I don't believe it is theoretically possible to hear east Asia or Australia on FM. Sure, transoceanic FM skip has happened (6/26/2009 was an example - Northern Ireland's Paul Logan received 94.1 WYSP Philadelphia, 97.3 WENJ in New Jersey, and 90.7 WVAS Montgomery, AL, the farthest distance at over 4,000 miles. That's triple-hop skip and has only happened once other than that.)
You are most likely listening at the wrong time. California was actually quite dry last year (2015) for e-skip, however, I did receive a nice opening early on June 21st into Los Angeles, and then San Diego up to 100.7 KFMB. KIFM, KSON, KMYI and KSSX were all in. Also XHHIT 95.3 (La Caliente). Use the TVFM Skip Log (DXworld.com/tvfmlog.html) to check for skip...there is usually a few people in the Southwest who log on there once in a while.
