Saw this on.... 'amps'...posted by Rob, K5UJ. "Saddened to see Bill Turner, W6WRT listed in July QST Silent Keys." ## Bill was a nice fellow, and provided some good insight + ideas / fixes on a lot of

Trus rms voltmeters work really good with ratty waveforms. They will handle anything you throw at em...including sawtooth, square waves, and loads of harmonics. True rms ac ammeters, good ones, have

What precision do you want? For what you probably want, I would think a true RMS volt meter of a known accuracy within a couple % and a known resistance should suffice as measuring the calibration,

A thermocouple meter will measure true RMS regardless of the waveform. Old school stuff.

A few years back, on some FB group I belonged to at the time, I forget which, somebody posted a picture of a large industrial transformer, I'll guess it was maybe 10' square and 8' tall, I really

If you look at the distorted waveform coming out of the FWB, FWCT, FWD, it typ consists of high, peak pulsed currents.... when a C filter is used. Like 15-24A on peaks....and only 1.5 to 1.7 msecs in

The recent glitch affected several on line plus classic email forums. Quit blaming Yahoo, etc when anything disturbs your lives Shit happens and the reason is often covered up. .

Please explain which groups that moved caused the traffic to drop to zero. I can give many groups that this did not happen. So which groups are you referring to? Doug "The difference between stupidity

I belong to a number of groups that moved and the traffic has dropped to nearly zero.

Please explain why "moving is not an answer"? ALL of other groups I belong to have moved with ZERO ISSUES on to groups.io After all groups.io is developed by former Yahoo people to be what Yahoo might
