Good point; perhaps the real cost savings isn't the radio itself, but that its absence allows them to cut corners (and cost) elsewhere on EMI measures? That said, my conversion doesn't need shielded conductors or a shield around the controller in order for AM to be perfectly usable, so I'm not sure where they would cut costs such that they needed to eliminate AM capability to "hide" their cost saving measures? Commercial EVs pretty much always have the controller in an aluminum enclosure, so it should be largely shielded for "free"; I doubt we'll see controllers in plastic boxes very soon ;^> Cheers, Roger. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
