[ARC5] AM on 40m?

I hear a large amount of AM on 75 here in the East.  The 40 meter window is a bit narrower than the 75 meter window, and I haven't heard a lot there.  One reason may be, it'd be difficult to get some of the x-BC transmitters to function on 40.  The RF circuit leads are too long.
I think most of the AM within the Vast Wasteland of 10 meters is between 29.0 and 29.3.  (I do enjoy 10 meters and work mobile SSB there sometimes.)

Speaking of BC transmitters (and here, again, I risk annihilation)... what is the rationale behind "Hy-Fye" audio on the ham bands?  When the QRM/QRN picks up, most of what the receiving op actually hears sounds a bit like Charlie Brown's teacher in "Peanuts" -- "whp-WAMP-wump-wup-Wank-WHOP-whup..." etc etc.  The BAAAAAAASS washes everything else out.
Some of these guys won't even talk with you if they find out you're running a lowly Command Set.
Broadcast transmitters are definitely good for one thing.  They make Reddy Kilowatt's glow bright red and stretch his eee-ville grin from ear to ear.... No, I'm not one bit envious.
Hmm, getting a BC transmitter, however, might be a good incentive for getting a new house.  I'd have to knock down an exterior wall, where I live now, to get one indoors.  Or maybe I could design a house around it.  (That's what was done, in many an AM BC station....)

    FWIW, I hear a fair amount of AM activity on both 75 and 
40 meters and some on 10 meters near the top of the band. 
Most stations are in the West but on 10 I have also heard 
some Eastern stations. AM is fun to play with but any 
listening will demonstrate quickly why SSB supplanted it. I 
am also a league member.
