Adaptive range tracking
It's been a long time but as I remember it you take the time and divide it by the speed of light at sea level. Thus range. Any doppler effects can be negated unless it is incomming.- rsbuck

Why does SR469 Show 4000% Current Unbalance
With the current imbalances you posted the motor must have melted down. We can assume that this is erroneous data. I installed a CT with 115AC exciter current one time.- rsbuck

How to Measure Phase of Signals
It sounds like a redundant exercise. With a gyroscope what you are measuring is the current induced in the opposing windings due to the precession of the gimbal. Then it is simple math.- rsbuck

How the braided copper wire is soldered into a carbon brush?
One thing I have done in the past with difficult to find brushes is to go to a motor shop which does DC motors. They have a lot of different size brushes in their stock. Find one close to yours and use fine emory paper to sand it to the size where it will fit in the brush sleeve in the motor. If...- rsbuck

Been 35+ yrs since taught and haven't used since. Outside my office is a plant loudspeaker. It has two wires powering it. The PA system was changed to where there is a very loud and annoying 1000HZ tone just before the message. I would like to filter out the 1000HZ with a choke coil and a...- rsbuck

Hey josephn16, Sorry I took so long to respond. The problem was solved (?) by moving the gas hi-limit switch down stream of the shutoff valve. I do not know it this is kosher but was following orders. The hi-limit switch has a mechanical reset by code. Problem is that with the overpressure in...- rsbuck

Tunnel oven gas pressure.
Hello all, I hope this is the right forum. I am new to this site but hope I may glean some knowledge on a natural gas regulator and outlet pressure. This is not my specialty but this problem has been thrust upon me. The 120 foot tunnel oven gas is supplied by 2" pipe through a regulator to a...- rsbuck
