I don't see how this can be true. The licensed facilities are the same.
Maybe the replacement tower (on which KFRC is diplexed) changed the
propagation?
Experts?

KVTO, 1400khz, doesn't traverse into Sactown as well as former
predecessor &
jazz legend KRE, "creative radio", did several decades ago!
Part of the problem is that the noise level is many dB higher now than it
was several decades ago, and the receivers no where near as good. (for
AMBCB). Many people have gone to using fluorescent lighting in the name of
saving some money, and there are many more modern conveniences that generate
RF noise (these need not be in your home to affect the noise floor in your
receiver). These include, but are not limited to, computers/monitors, light
dimmers, coffee makers, digital clocks, microwave ovens, etc..
Most significant though is the receivers today are inferior to those back
then. AM is pretty much an afterthought in anything but a car radio anymore.
Home receivers' AM sections are next to worthless, unless you own something
like a Carver TX-11a or 11b. An onld AA5 table radio was ten times the radio
that the AM sections in most home receivers are. For starters, home stereos
don't even use a tuned antenna for AM anymore, just a broadband input
section with a simple bandpass filter.
