Re: Disk Brakes and AM Radio Reception

[Hal Taylor <taylor@domain.elided>]

On second thought, maybe we should strike that.  I must be tired.  Reconsidering
this guess, it would seem that the modulation from ABS should only come at the
point of lock, which is not what you describe.  Guess #2 is that you've got
semi-metallic brake paids, and the friction on the rotors is generating static.
What about trying a different type of pad (still guessing, of course).

Or what about just finding some FM stations so that I can go to bed now and stop
hypothosizing about things I know nothing about...?

:^)

Good luck, in any event.
