WOR off the air for the 4th

I wish I knew about the WOR outage last night. When WOR was temporarily off the air 5 years ago, I got Radio Rebelde from Cuba and WKOO Rose Hill, NC. The latter should've sign off at sunset.

Here's Radio Rebelde and Classic Country music mixing on 710 from 5/13/2021.
Here's Radio Rebelde by itself on the same day.

Why would they be effected by heat?
All electronics are sensitive to temperature. If you took your phone or tablet and set it on the sidewalk in the sun for 10-20 minutes, it would probably refuse to operate "until it cools down."

Transmitters are the same way, just bigger. They are big enough that they generate meaningful heat on their own. You could probably heat a small apartment building (4-6 units) with the waste heat from the WOR transmitter. That's a problem, on a hot summer's day, when everything is already hot enough.

I get heat is bad, but why don’t more stations go down. They all had the same conditions.

I've seen posts on the various boards here about several stations, including a station in Vineland NJ being off yesterday.


It mainly affected AM stations. Most of NYC's FM stations are in the ESB. They pay a lot for being there, and some of it is for AC.

It wasn't that hot in New York over the weekend, relative to what you might get in Dallas, Tuscon or Rio de Janiero, so clearly we know how to design transmitters to endure heat for days on end.

Obviously WOR had some kind of equipment failure. We don't have any way to know what kind, and we will probably never find out. Being a major AM station in market #1, they have lots of redundant systems, including a generator and a backup transmitter.
