Need info on an AM antenna array

Did you try this site?

https://www.fcc.gov/media/radio/am-query

It appears from radio-locator.com

http://radio-locator.com/info/WDMV-AM

the station you are looking for is WDMV-AM

Info is available at the above link

Having a problem or otherwise being impacted by that facility/station?

Have you approached them to discuss your problem (presuming you have one)

Several years ago I updated the antenna POI using data pulled from the FCC database. It is a convoluted process as the AM, FM and TV station databases are different and building a workable POI is a mess. I should really go the process again and generate a new POI for this site. Will probably take me a few hours to review what I did to create the current ones in the first place.

However, other than callsigns, it is very rare for a transmitter to actually move. AM sites, often taking up a lot of real estate with their arrays, tend to stay in the same place for decades. FM stations move a bit easier.

It’s hard to tell what the OP’s problem is with the AM transmitter. I’m guessing its RF interference of some sort. I know from experience that living in close proximity to an AM radio station can cause many issues, most of which are not the fault of the broadcaster.

Although a bit technical, this site helped a great deal with my problems:

I tend to agree with your assessment the problem, should there be one isn't likely the stations fault.

Most station operators, commercial or amateur are usually very willing to help, recommend and in some cases diag a problem for / with someone being impacted.

Usually cheaper than having to respond to the FCC because of s formal interference complaint.

Back in the 1970's, my grandparents lived in Ridgewood, Queens, NYC, not far from what was then WQXR on 1560kHz running 50,000 watts. For the longest time, their telephone received the station. They did not mind too much because it was classical music. Eventually the phone company fixed it and that lasted for several years. Then the phone company did some line work on the building and the station was back on her phone. They never bothered to have it fixed after that.

Generally, correcting interference from a radio station is the responsibility of the device's owner UNLESS the station is not operating legally (transmitter out of spec for example). Many stations will give you advice and point you to service people who can help but none, unless they are legally stupid, will attempt the fix themselves. I am an amateur radio operator and we are reminded not to attempt to fix a neighbors problematic device as we could be held legally responsible if we damage it (such as putting filter capacitors on the speaker outputs of a modern amplifier - NOT GOOD!). If we are operating legally and a technically compliant station, then the onus is on the owner of the equipment.
