Nulls in signal pattern maps aren't always what they seem just by looking at them.
WWKB 1520 from Buffalo is a good example. You'd think they couldn't be heard at all in the midwest or Florida at night but I know some here have picked them up in the midwest and I've actually heard them here in Florida.
Totally agree. As WKBW, I used to hear it nightly during my college days in the late '60s under KOMA. Supposedly they have the same pattern now as then, but if you look at Radio Locator's map, they'd appear to be sending almost no juice to the west-southwest.
As for KGO... It's been 16 years, but I thought I remembered hearing it one night in Maui, although David responded to my post on another thread here with a comment about the null, so I just assumed my memory was faulty. Now, I'm thinking maybe I was remembering correctly after all.
(Sidebar comment for David.... Do you work in that Univision complex north of LAX off the 405? I drove by there Monday, as I do just about every time I'm in So Cal. I'm usually heading from LAX or Orange County up the hill for customer meetings in Encino and/or Van Nuys. I also sometimes stay at the Marriott Courtyard across the road and a half-mile or so north. I said "drove by". That was the case Monday, but usually it's "crawl by"!)
