Yes -- IF the transformer did not pick up magnetic fields from the vehicle's systems. I saw that when doing testing of some pro mics for RFI in a Volvo S80 -- the output transformer in the mic was not shielded, and picked up trash. That would be fixed with a transformer that has a mu-metal shield, but shielded transformers are expensive. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
