KFAN 1130 the Splash MONSTER, 90 khz wide iBOC

Well, whatever gremlin had KFUO's iBOC "sparkling" way off to the sides last year is currently afflicting KFAN 1130 in Mpls/St Paul.

I am working in St Cloud MN, and while driving out, I was checking the locals with a *NEW* radio this time, in a rental car.
The Chrysler stock radio rolls off AM about 3500 hz. The treble adjust makes a tiny difference.
The lack of a tuned RF stage on this radio is maddening! I am accustomed to hearing twice as many signals in daytime here.
At least the awful sounding Delco/Delphis had reasonable sensitivity.

I have no idea whether or not the HD was decodable. My rental car has Sirius.
The swirlies in stereo are far more nauseating than platform motion was in CQUAM.
I'm looking for an "ugh" emoticon with the toungue sticking out.

Oh, and even with the PLL detector and the high end rolled off at 3500 I still hear the hiss.
But I also notice that this radio makes all AMs sound about as bad as AMs with iBOC.
The low RF sensitivity adds a good deal of detector hiss that wouldn't be there with proper design.

I'll try to find a working HD radio in St Cloud tomorrow.
One of my co-workers, who lives up 'round here, overheard me discussing this with someone else, and asked if this
was why WCCO AM sounds awful these days. I filled him in.
 
Ugh. KFUO could get better-sounding analog AM with a Fessenden rotary spark-gap voice transmitter, and it probably wouldn't splatter off-channel any worse than the IBOC, with good filtering.
