A local has some HID sockets in his basement workshop.  Wants to replace the CFL with some much higher lumen output units.  He bought some from ebay but the RFI is off the scale.  Massive. Any recomm

The easy alternative is just to use a dual speed pump.  The energy savings is not quite as ideal as the variable type, but being a conventional motor, they produce ZERO RFI. 73/jeff/ac0c alpha-charli

That's a very good idea. With one of the pole arc issues locally which was particularly bad, I asked the power guy what the chance of that arc starting a fire.  After all, the pole is near a farmers

We are looking at a replacement HVAC and these items are proposed for the install.  I'm paranoid about the RFI noise profile out of modern HVAC systems and would be interested in any comments. The Le

The compressor looks like a single speed, traditional unit. Definitely not variable speed. The furnace is a dual speed blower.  What I'm unclear on - is this a traditional dual-speed (no electronics

Thanks for that link Steve.  It looks like this Lennox heater uses exactly that 5-speed constant torque motor.  In looking at how those motors are constructed, and the layout of the control board, I

I looked into the similar family 2-stage compressor unit.  Seems the 2-stage is done with respect to the fluid / gas compressive loading applied to a SINGLE speed motor.  So from my review of the man

Lloyd, I have a dozen of those in my barn, and another 10 or so in my garage.  All perfectly RFI quiet.  I need to check on what the specific gadget was that my electrician put up but they have been
