Undetermined in one case due to a high ambient RFI level, in another none yet observed, and in yet others (mentioned in other threads) significant RFI. My observation was rhetorical. If the wall war

Looked at both sites (I am an aggressive Google user) and as is often the case the answer is buried out there and I may spend hours looking and still not find the technically relevant answer I seek.

I think I will go back to the original plan. Start with a pair of 12v batteries in series and drop the voltage to 19 and 16 v using a couple of zeners, some resistors, and regulators. I am guessing t

Author: kd4e <kd4e@verizon.net>

It is reasonable to presume that a 12v fan not labeled "brushless" has brushes and is thus more likely to generate RFI? http://www.buyextras.com/bev12albalbe.html -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Is is probable that the radio manufacturers used only brushless fans or have taken other means to assure that noise is not generated by the fans they selected? I'd hate to install several of these ar

buyextras looks like a good company! They just replied and actually had the answer, the fans are brushless. Gonna get five and hope they work out OK. Will advise if they get RF noisy. Tnx! doc -- ~~~

I never buy new cars but would pay at least $100. for a service that implemented a genuine RFI quieting package to a used car. If I were to buy a $10,000+ new vehicle I'd hardly blink at adding $100.
