If all you get is S3 with the engine running, that is 4-to-5 S-units lower than me. My truck is an EMI nightmare, the alternator diodes are 21 years old, the ignition overtakes a 50,000 watt commercial clear channel AM station and the CD player turns out not to need an FM adapter... Hams a block away hate me, but I still like my rolling tetanus, radio-black-out experiment! :-)
