Another item to add to the mix is image rejection on the receiver receiving the interference and the possible combinations local oscilator harmonics, interfering signal and image frequency.

Given that the Weather transmitter appears to be in an RF rich environment, it could be intermod with all the local transmitters in something like a corroded overlap on tower legs.

In our area we have lost the usability of two different repeater frequencies to intermod problems. Both transmitters were in RF rich environments. Too many transmitters, too much power and local metal buildings yeilds problems for all.

It's been a while, but unfortunately the KWO35 transmitter is still off the air. I find it very difficult to believe that given all the expertise that is available to solve this issue, that it has not been solved.
Is there another issue besides the interference that is keeping the transmitter down?

Perhaps, instead of looking for a new site in NYC, the transmitter should be moved into NJ. While that move may reduce coverage over maritime areas, it might eliminate the interference issue, and having some coverage would be better than none.

OTOH, it might be time to reevaluate the entire NOAA weather radio program. Is it still needed?
How far offshore can someone reliably connect with the Internet?
