Denver, CO - HD AM noise from 670 KLTT. Lost cause.
Retro/historic - In central Missouri in the 1980s, received, at various times, KNBR, KKYX San Antonio, and even KFEQ St. Joseph, MO at midnight. But let's talk about KFEQ for a moment. It's one of those longtime Midwest stations focused on farm news for a large region. For years, it was run by Gene Millard, a well-respected broadcaster in Missouri (who's still around!) with a solid commitment to news and public service. Considering circumstances these days, it's still a pretty good station. KFEQ's nighttime DA is pretty much a north-south figure-8, so when I got it in Columbia, considerably east and south of St. Joe, that midnight in 1980.
It's been about 18 or 19 months since this frequency came around on the forum; last time it did, I was visiting Santa Fe, NM on a house-hunting trip (didn't end up there) and picked up KNBR at night, a bit noisy but quite steady.
And, of course, when I lived in the Bay Area, KNBR was a constant.
