Rotary Switches
Can anyone tell me how to select unmarked wafer switches for RF switching, such as e-shopping at Surplus Sales? What is the general rule regarding contact spacing vs HV? If unmarked, how do I get into

Re: 3 - phase HV supply
Denny, A rotary converter (pony motor) is the only way to do it correctly. A static converter is simply a started capacitor bank to get the motor up to speed then it drops out letting the motor run on

Re: 3 - phase HV supply
Being that my Bridgeport mill is 1.5 HP, I use a rotary convertor to change the 220X1 to 220X3... Not perfect but it works... I did consider asking Consumers Power Co. to give me a price for 3 phase

Yeah, that's what I am doing... We quickly metered the remaining four... They are good, but two had drifted out of the 5% range a small amount and two were still in range... Each one is dissipating

Re: 3 - phase HV supply
A 3 phase service is mighty fine to have if one can afford to have it put in. I've not checked on the price in a while, but back in 1985, a 200 amp 220 volt service ran around $2000 from the power

Some of those with good technical knowledge are Tom's pals. My take on Tom is that he attracts people who share a common element in their childhoods. Apparently, the attraction is so strong that a

There will be no improvement as long transmitting bandwith is limited or with poor audio response. In Germany we are limited to 2,7KHz bandwith anyway, except on 10m. 73 Peter
