I had seen that advice somewhere --- maybe in this NG a while back --- and
I've tried it. No luck.
Sometimes external inputs DO make a difference. Sometimes it seems like the
smoothness or roughness of the pavement can influence it, and although I
would not characterize the interference as "ignition sourced" I've been
curious about IMPROVEMENTS in reception (temporary of course) when I pull
the shifter down to 2nd and accelerate. It's probably just a coincidence.
