It is. It's funny though. that if you look at the patterns side by side, in the absolute nulls, KGO's signal might theoretically be weaker that KSFO on night pattern. After the big earthquake which I think was in 1989, I read in one of the engineering publications that since at least one of the KGO towers was destroyed or damaged, KGO's engineers contacted the FCC to ask how much power that they could run in just one tower to get back on the air with a temporary non-directional signal and apparently they were told 20 kW!Right. But it’s different from KSFO’s nighttime pattern.
