10 kHz AM Frequency of the Week - 570 kHz

Warminster PA(Philly 'burbs):

Daytime: splatter from 560 WFIL or a very weak WMCA from NYC.
Night: WMCA, much stronger.

Just semi-OT---WMCA was the only 570 heard by me in Bermuda in the daytime, and reception wasn't bad! They once applied for 50k daytime, but I am not sure that they ever went thru with it....that sure would be a tight lobe, with 560 Philly next door.

It was six towers for 50/30 U4 (DA-2) WMCA. It was a CP. I archived the database on another computer. I'll try to find it. It was another row of towers probably on the order of 1/2 wavelength apart from the existing row. That is 863 feet. When you add 300+ foot radials on all sides, the land acquisition costs become prohibitive. The length of the land for untruncated radials plus towers with just three towers, is more than 1/4 mile, and at least 20 acres for three towers. Another row would be at least 40 acres, and possibly more. Too bad they couldn't have done that when AM was highly profitable. It would have been an awesome signal over New York.
 
I don't know if this link will work.

Looks like it is built just above the water or in a marsh.

It would've really helped them compete with WABC if they could've done that in the 60s. I'll bet that WFIL would've protested vehemently to the FCC had WMCA been able to try it.
 
Zooming in on that link, the site is clearly under water. That in and of itself is good and bad. Good because the site conductivity is probably on the order of 1000 millimhos per meter. I say that because that's what certain nearly landlocked water areas close to the ocean show on international conductivity maps. Not 5000, but very conductive. Bad because the construction costs are probably very high. And you'd have to just about get self supporters, if it fits the site at all. I believe the same man selling the Brooklyn Bridge is selling swamp land in New Jersey, but it's reasonable except for the environmental restrictions.
 
Sorry Scott, I didn't think to look at your site first for pictures.

Also, the 1000 mmhos/m would probably be in the sounds. I was thinking the site was closer to the sounds and oceans. It probably is still relatively salty though.
