I think they've been around a long time, but I'm not sure when they started showing up. In general, its better to stop the noise at its source. These boxes only stop noise that is carried on the 12V line, but they're very effective at that. They can't do anything for noise that comes in the antenna (radiated noise such as ignition noise.) - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- Unsubscribe? mailto:type3-request@vwtype3.org, Subject: unsubscribe
