AM Frequency of the Week - 750 kHz

Houston daytime - blank. I am far enough from KTRH 740 to clear the interference. I have tried many times for WSB daytime but have not logged it. NIght is all WBS, of course.

About 8 or 9 years ago, I did extensive testing of 4 and 5 foot loops in Lubbock, TX, and was able to easily log WSB. Ground conductivity there is high, but 1000 mile daytime AM reception is characterized by deep fades lasting from several minutes to a couple of hours.

Man could you imagine if their calls WERE WBS?

that would have made for some GREAT promotions.

If they were a '60s top 40 station, instead of the "good guys", they could call themselves the "BS-ers"!
 
I could totally see that call being applied to just about any political talker!

WSB's daytime signal is only good for about 200-220 miles.

I had a weak, but dependable daytime signal from WBB when I lived in Daytona Beach, FL. On trips to Jacksonville they were very strong and listenable. Nothing when I moved to Melbourne, FL.

WSB - dang sticky keyboard. And I've cleaned the darn thing!
 
30 Miles south of Indy...

Day :

WNDZ at 170 miles...I'm in the depth of their null. Something is beating against them but considering that it's weaker than WNDZ's very weak signal, I'll never figure it out. They used to come in here much better years ago than now.

Night : the almighty WSB
 
Dallas was interesting. KSEO Durant OK - it used to be a legacy oldies station. Quite listenable until KAAM started fooling with the stupid HD radio. Now KSEO is sports format.

WNDZ does have a lobe going ESE. Maybe you're getting a little bit off that.

Does good ground conductivity actually help a skywave signal? I was always under the impression it helped only groundwave.

WSB is a good test case for this, inasmuch as the conductivity of the earth near the WSB radiator is rather poor according to the FCC M-3 map, and the fact that WSB uses a lengthy and dense, elevated network of wires over a shopping center as most of their r-f ground return (a counterpoise, really).

But nighttime, skywave MW fields are not very dependent upon ground plane conductivity beyond 1/2 wavelength from the transmit antenna (details on request).

This is shown by the fact that the nighttime skywave field of WSB often is on a par with WJR Detroit (50 kW 24/7 omni on 760 kHz) at my receiving location, for about the same path distance and ionospheric conditions for both stations -- even though earth conductivity near the WJR antenna is quite a bit better than that around the WSB antenna.

That's what I thought. Thank you for confirming this.

I think it is all ground conductivity at the receiving - not transmitting site that is WSB's problem. My daytime reception in Florida and even Lubbock, TX proves that beyond any doubt - there is nothing wrong with WSB's transmitter array, they just have the bad luck of their listeners in the immediate area over bad conductivity.
