KCBX says increased tropospheric ducting due to warmer water makes repeater KSBX (89.5/Santa Barbara) unlistenable in its coverage area.

When I was in Southern California a few months back, I was really surprised at how good distant signals from all over the coast came in.

This map shows, even at the winter solstice, there is some ducting going on between the Santa Barbara area and San Diego: <https://dxinfocentre.com/tropo_enp.html>
