Some unid likely outband stations were speaking Spanish, way up in 10 (29446.5) where they're not usually heard. They were in LSB, while amateur transceivers typically use USB on this band.
Also a brief voice opening to Europe. This path is still going on a weak-signal mode called JT65, though the band appears to be doing its daily shift to South America and later most likely to the Pacific.
Here are some JT65 hits in Southern California. The columns are UTC time, sync quality, strength in dB (I forgot the zero reference), offset in start time from 00 seconds (on your local clock), offset in Hz from 28076.000 kHz, and message exchanged. The countries in () were added by myself for identification.
