Whenever my radio is tuned to a marginal AM signal, I hear a burst of static
as I shift from 3rd to 4th.  It is the same sound I expect to hear when I
rachet the headlight relay.  In my moments of idleness, I have pondered the
reason that this charge in transition presents itself, but I find no real
satisfaction in my speculation.  For no other reason than curiosity, does
anyone have an explanation of what might be causing this bump in the ether?
