The sad part about all of this is it wouldn't cost any manufacturer 
anything to correct 99% problems. It is a simple case of the 
designers either not understanding how to select component values or 
how to switch things, or the service and sales people not telling 
them they have a problem.

Think of this. All the radios being sold with bandwidth problems will 
be on the air until most of us are dead and buried. Unless people 
start fixing the radios, or the manufacturers do, the problem can 
only get worse and worse.

FCC regs clearly say we are NOT allowed to cause harmful interference 
outside the "good engineering practice" BW for the mode we are on.  
That also includes spurious emissions, so despite ICOM's claims they 
were "within spec" spurious emissions that cause harmful interference 
are illegal....and that includes the keyclicks many radios have.73,
