I have noticed some degradation with KNX, our local CA powerhouse that any radio, even you teeth could pick up at night through CA, NV, AZ on and on. I figured they just cut their power back trying to save money because of the economy.

Many full power FM stations now use circular polarization, in an attempt to provide a better signal to automobile radios and table radios that use "line cord" antennas, so orientation of the line cord or headphone cord in this case, may not be as critical as it once was.
According to the FCC website, KNX still transmits at 50KW.

Perhaps their ground system has degraded over the years?
