I have been monitoring the WRAL business frequencies for several decades. I have noticed something like “intermod” around 7pm. Basically the frequency will play on air audio. Now, WRAL hasn’t been analog for decades (nor a reliable news source, either). I have noticed a significant amount of traffic on WRAL and WTVD, which is good. Just wondering if I am crazy.

That's difficult to respond to since you don't mention frequencies you are hearing it on or the type of intermod you are hearing.
To add to the above, time expired for editing, I have also heard TV activity on the following frequencies, usually remote audio to reporters on the scene doing lives.
TV 5 WRAL
450.4125 Sky 5
450.3875
450.5125
TV 11 WTVD
450.1125
450.2125 Helo "47"
450.8375
450.8625
These are unknown what station
450.375
451.6125
455.775

I don't know the exact frequency since I have gotten spoiled with alphanumeric scanners. I just started noticing it in the past week or two. At first I thought it was someone accidentally keying their mic.

if you hearing over the air audio it could be the ifb ear pieces . is it a constant stream . does it happen during the newscast time blocks . most stations use a cell phone to dial into the control room to feed the audio to them . but some do use the uhf 450 mhz rp freqs .
Very good observation. I think we have a winner!!!!
I'm fairly confident what you're hearing is a remote broadcast via equipment such as "Marti". Radio/TV Stations use these system for remote broadcast at various sites. These types of systems have been in place since the 70s, possibly earlier. here's a photo of a Marti transmitter that broadcasts on 450.3875mhz.
