Isn't 1360's ground system in bad shape? I doubt CC cares about it much since it isn't a money maker like WLW. Even 10 years ago it had a better signal than is has now.
The condition of a ground system has less to do with an AM signal than it gets credit for. This topic has been discussed on the Engineering boards & even in the extreme case of going from a few ground rods to a full ground system, the difference in signal was in the single digit percents IIRC. Factoring out the fact that the Cincinnati metro was less spread out 45 years ago, the AM band is a different animal today & the factors that are often ignored include directional antennas that protect WSAI possibly not being in compliance & therefore sending more interference this way and here's the biggie : All of these stations on 1360 that operate with low power at night (example, WFLW Monticello,KY--just 170 miles from WSAI) did not operate at night at the time. 20 watts isn't always easy to measure...are all of these stations actually operating at their licensed flea power? Are all of them powering down at all from their day power? Are some of them purposely staying on day power on nights they air high school sports (yes, this does happen)? The sad fact is that AM compliance was once sacred. A station couldn't meet it's night time license terms and it went off the air at sundown--no questions asked. WSAI had a fire in 1969 that didn't allow their directional antenna to work...they went off the air at sunset--even though they had huge ratings. Eventually they got special permission to operate with 250 watts at night. The fact is that AM compliance rates somewhere below stocking the restrooms with paper towels...and the result is that the AM dial has more interference--quite a bit more--than it once did. Same thing in Indiana...in 1978, the #1 station in Columbus,IN at night was WNDE 1260 from Indianapolis. WNDE has the exact same facilities now as in 1978. But I dare you to pull them from the jumble of stations on 1260 in Columbus at night.
Bob, i must respectfully disagree with you on this. We've got a bunch of real world experience with this. I have had stations with essentially no ground system. Had an awful time covering the market. Our old "600" site, built in the 40's, had a ground system that totally eroded. The signal went right down with it. We have been going through our AM's, replacing the ground systems. Holy cow, what a difference. So dramatic was this repair job on our 1390, that, as previously mentioned, we are fixing them all.
