AM IBOC interference example

[Tom Wells]

Clear Channel's AM-1390 WGRB on the south side of Chicago has had IBOC on for quite a while now.
They are injecting significant noise into the protected contour area of WRMN AM 1410 in Elgin Illinois.
I am unable to demodulate 1410 without having the IBOC hiss intermodulate.
And this is with a continuous-tuning receiver, so yes, I did try tuning to the upper sideband of WRMN.
Where do I send the Notice of apparent Liability, the FCC, Clear Channel or Ibiquity?
What is the recourse for the station owner? Can HE Sue to have WGRB install a directional array?

I won't put in a link to Radio Locator, but at your convenience.......

Please examine the coverage areas of these two stations and if anyone can, please explain why it is
permissable for one of these to interfere with the other, when geographic and frequency allocations
made it possible for these to coexist peacefully for so many years?

There are LOTS of small station owners who are very upset at big gun stations that reside within 30 KHz. of their allocations which have turned on AM IBOC. More of these problems will be surfacing in the large markets.

Trouble is a-brewing, and the readers of this topic on the Radio-Info message board heard it here first.

It is brewing, that's all I will say...
