A GOOD PRACTICE: Whenever I pick up the end of a coaxial cable, I *always *hold a finger across the end "shorting" the center conductor to the backshell before connecting it to anything. Doesn't

Some years ago I helped chase down an interferer whose signal was drifting through the input frequency ranges of a bunch of 2-meter ham repeaters in our area.? It came and went, and when present had

Add to this list people who routinely mix up "B" for bytes and "b" for bits, especially in the networking part of the computer world.

Dave, W0LEV, is correct. The metric prefixes are well-defined. See https://en.m.wikipedia.org/wiki/Metric_prefix for a list of them. One of the ones that people screw up is milli (m) vs. mega (M).

Yes, I have one generator that goes to ?Hz. But I'm not a typical ham by any means! If you build yourself a seismometer, you're in the mHz region. Dave - W?LEV [email protected]> wrote:

Hate to burst your bubble Dave, but the HP-3561A , in their documentation, refers to the low frequency coverage (micro Hz) as uHz, and how about kHz. So, yeah, mHz for "mili Hz" works for me but hey

Yea, Don, get the newbies to use proper abbreviations! I've called it out many times, but it seems to fall on deaf ears and clearly never reaches the gray matter. What really gets my goat is "mhz".

One word. MOVE. Mike C. Sand Mtn GA PS Better yet, drop a #10 gauge wire straight out your window, shove it into the ground (bare) then connect the other end, 'CAREFULLY', to your ground lug on the

I am very unfortunate in that my townhouse has both dirty electricity and dirty ground in the outlets. I had been using grounding mats/ sheets in my bed. After some testing I found out that current

I can attest to that for sure (discharging cables). As a lead tech, working for uncle sugar many years ago at NNSY (Norfolk Naval Shipyard), I was assigned to re hook-up a long wire antenna on top of

My observation is that very few people use units of dbW even when working at high power, dbm (relative to 1 milliwatt) being far more common. If a colleague started using dBW I would ask them why as I

One of the best things you can do to prevent ESD failures is to develop a habit of discharging any cable before you mate it with any kind of equipment.? Cables can acquire a many-thousand volts

Unless an input or output is marked, as happens with some very high-power attenuators, I assume they are bidirectional.? They are generally Pi or T topology and thus symmetrical. A notable exception,

Agree, but not everybody has such a sensor -- Designer of the tinySA For more info go to https://tinysa.org/wiki

M preferred method of dealing with an unknown signal is by using a wideband power sensor and slowly approaching the mating connector with the unknown signal, I can sense a whopping signal by

No special settings. Center the sweep frequency in the center of the QRM with minimum span to cover the unwanted signal. RBW should be on auto. Narrow the span tightly on one spike if the signal is

Bruce Akhusrst, Roger Hartel: Thank you. Of course they came from AliExpress. Anyway, they are working and I can use them for my humble needs. Neither the seller (except one!) nor the manufacturer's

Quite a lot of cheap (and not so cheap) low power chinese attenuators DO declare an input side in datasheets.? ?This is not done for fun.? ? ? It is almost always the male plug side that is
