"Is 760 KFMB San Diego, CA, USA possible there? It's 50kW directional with a lotta power aimed out that way. Their transmitter site is about 7.3 miles from me at a heading of 320°, and they are the strongest nighttime station here.
Also what about 640 KFI Los Angeles? It's not exactly a local for me, but does come in fairly well throughout the day. I'm basically right at the zone of their groundwave coverage where it equals their skywave signal, or at least is within a few dB or so. And is 580 KMJ Fresno possible there as well? It's 50kW, directional with a lot of power aimed due west".
I have heard 760 KFMB & 640 KFI but they are rare. Splash from nearby aussies makes life tough. I've heard bits of KMJ but never an ID. Its hard gettig IDs now, since many may only ID once an hour (usually TOH).
Most US stations are heard between 0700 ~ 1000 UTC. The W calls are very rare catches & I normally hear them around Oct/Nov, west coast is best around march & Latin America usually best in April/May.
That's incredible that you heard WFAN. I'm truly amazed!
