Could having dropped a spark-plug (REM38E in a Lyc O-360-A2D) cause
static in the radio when on one mag with none on the other mag? What
other consequences might there be from a dropped plug? I've been
wrestling with a static problem on one mag in the radio. I got some
good advice here previously, but just remembered that I did drop a plug
on the floor and put it back. Don't know if this is when the problem
started or not. Can't remember. Thanks.

Yes, a hairline crack in the ceramic can cause the static problem you
are experiencing. It can also impact performance or cause the plug to
fail prematurely.

Static on the radio can be caused by failing insulation in the plug
wires
too.
