1080 has been a mushy frequency around Columbus as long as I can remember. I remember hearing WTIC back into the 80s, and while it was never strong it's even weaker now than I thought it was then. Now, of course, I know that's because of KRLD.
I've only caught KRLD one time around here, and that was about 15 years ago on a rainy day in early January 2007. This was probably around 6 p.m. our time, so before they went to the night pattern that nulls toward WTIC, and while the signal was never loud it was pretty listenable for 15 minutes or so. Later that night when I checked, nothing. Whenever I've checked since then, nothing.
Reports I've read here say KRLD is listenable as close to me as parts of Kentucky, so a few hundred miles southwest.
