WKRC - 550-AM - Reception

[fedacct1]

One day when i have good reception here in Wyoming, i'll record a bit of 1530 Cincy and post it here

I have generally not gotten WCKY over long distances although I did receive them on vacation in the Bahamas once but could not get WLW. AM signals higher up the dial do not travel as well as at the lower end.

That's true for daytime ground wave but not for nighttime sky wave.

But do you know of any station that monetizes skywave any more?

Greetings everyone!

East of Washington DC WCKY 1530 can be heard at night. Obviously, so can WLW. Several days recently at night, I started my car to hear WLW coming in fine. I was in a parking garage in DC...

About AM night signals getting worse- considering fewer eyes on facilities, there is always the possibility stations are not operating at correct night time power. It only takes one station to mess up night time coverage of a clear channel station over a wide area. It can go on for days or weeks, until it is resolved.

It can go the other way, legally! I recall KCBS skywave routinely clobbered co-channel KBRT in the LA basin just about sundown.

Well first thought is if a tree falls in the forest, does anybody hear it? Yes KBRT is now operating at night I assume its cheaper to do that than to sign off at sunset. They used to sign off 15 minutes or so AFTER sunset. So with their 50kw signal dropping off a cliff to 190 watts at sunset, then KCBS blasts on top MOST of the time even here in Orange County, CA (where I live). I remember there USED to be an FCC rule about 50,000 watt stations could not reduce night time power so severely.

Way back in the 60's we had Robin Mathis and his 50 kw day and 250 watt night stations in Mississippi in places like Magee and Houston.

I believe KBRT's schedule when it operated daytime only was based on sunset times in San Francisco which are, indeed, on average 15 minutes later than in LA.

Interestingly, KBRT 740 is responsible for another power anomaly two channels up the dial. KFMB 760 San Diego is limited to 5,000 watts daytime but increases to 50,000 watts at night when KBRT reduces power.

Thanks, David, that makes total sense, I should have known haha

Now THAT I knew. Cool thanks

And KFMB should not even be on 760, but the FCC had to accomodate them when the revision to the NARBA treaty gave full rights to Mexico for 540 where KFMB lived at the time. In the 60's, Mexico got XEWA in San Luis Potos?* with 150 kw, and the FCC allowed KFMB to be on WJR's 1-A clear channel as it was the most viable alternative that maintained the same approximate coverage of the 540 operation, but it required bending the rules in several aspects.
