[QUOTE="Robert Lofgren, post: 90368, member: 2447"] Re: Monitor out whine Reminds me of some old honda car I once had... I installed an alarm in my car and when done I noticed that the piezo siren was sounding but at some lower level than usual. I thouht that I'd pulled some of the cable insulation when routing the cable to the siren so I decided to cut the + wire and fix the problem the next day. The siren was still sounding! I cursed and cut the other wire as well and the siren WAS STILL SOUNDING!!! I showed this to my friends on site and they thought I was just trying to joke with them. I wasn't easy to just remove the siren as I'd mounted it in a very 'secure position'. After a long and troublesome investigation I found the origin of my problems - It was the pwm for the dashboard dimmer! For some reason it caused so much rfi that it made the piezo oscillate... Just my luck :-( [/QUOTE]
