[Spooks] IF Jamming SSW of NOLA?

[Utility World (Hugh Stegman)]

>Have there been reports of IF (intermediate frequency)
jamming south-southwest of New Orleans?

Someone involved with the HF ham radio relief effort reported a strong
transmitter on 455 kHz blocking their receiver. I can't get any further
information, despite asking around.  I certainly cannot determine whether or
not there is any factual basis to any of this.

Most FM radios with 10.7 IFs are dual conversion with a second IF at 455.
