EVERYONE has the right to *know exactly what they are buying into* when offering any sort of help.

The world is *awash* with schemers and scammers who try to circumvent one's basic right not to be cheated.

Usenet is full of the fuckers.

Phil accuses me of being autistic. He's right.

Autism works for me.

Bill isn't autistic, he's just useless.

And he does use it so often that he clearly can't be getting it right most of the time. Just for the record I'm not remotely autistic, and I've spent a lot of time hanging around with psychologists who do know what the word means (which Phil clearly doesn't).

It's far from irrelevant, that's why it has been asked.

He seems to prefer providing negative value to discussions.

There are several ways to do what mkr wants. He doesn't have to disclose his purpose, but many aren't going to explain a pile of options most of which won't be the best for mkr's purpose. Shrug.

But Phil had snipped most of my comment - which wasn't "total crap". Phil's text chopping is a nasty habit.

It's Phil's idea of a fact, which is rather like his idea that he can make his responses look less pathetic by snipping its out of what he was responding to,

Phil seems to think that snipping chunks out of what he is responding to, and not marking the snips, is some kind of "fair comment".
It's not.

Up to a point. We typically waste a lot of time putting forward "solutions" that the OP can't use. There would less time wasted if if the OPs were more specific.

If it might tell the competition what you had in mind, your bosses aren't going to be happy.

Phil doesn't seem to have ever worked as part of a team, and he's got a blind spot here.

John might be somewhere on the autism spectrum - more Asbergers than full-blown autistic.

> Autism works for me.

It wouldn't. Managing a team of other engineers requires better social interaction than people of the autism spectrum can manage,

> Bill isn't autistic, he's just useless.

Not being useful to John Larkin means that I don't provide the flattery he craves.Since I've got a couple of patents, and have published a paper that has been cited more than twenty times I'm not entirely useless, though I don't seem to be useful in any way that John Larkin wants to exploit.

Tabby has the same kind of problem as John Larkin - he wants to be taken seriously, and he's an even poorer candidate for being taken seriously than John is.

> There are several ways to do what mkr wants. He doesn't have to disclose his purpose, but many aren't going to explain a pile of options most of which won't be the best for mkr's purpose. Shrug.

Mkr has provided more of the information we need than he did in his original post. He has also utterly failed to show any sign of thinking about the suggestions that he has got. A shrug does seem to be the appropriate response.

It isn't. Tabby is rather fond of posting nonsense, and he resents better-informed comment.

It's obviously true. There's nothing the user-group rules that spells out how much information a posted question has to contain.

It's well known that most such questions don't say enough about what the poster has in mind, but what might be "enough" isn't well-defined.

How can you be being cheated by somebody who asks for help for free? The only recompense on offer is the opportunity to be seen to perform well in a public forum.

None that Phil can understand, but Phil does seem to have quite a lot of problems understanding social transactions (as people who suffer from autism are reputed to do).

Hiding the purpose denies posters here the *right to chose* what they are happy to help with or not.
Matters a lot to serious posters using their real identity.

Ok, you talked me into it and it's real simple.

This group always has some rude motherfucker show up in the midst of someone's post and then take it to a level where they can vent and be hostile about the fact that they were the kid that was picked on in grade school.

Yes, and I was the guy who stole Phil's briefcase and threw the dodgeball at his fucking head while everybody laughed. "Phil" (man that alone sucks), is a lifelong dork who wants his revenge. If we were face to face, even at my age -- the goofy prick would run in fear because I'd kick his ass and humiliate him. Something that he knows all too well.

Kiss my ass you fucking nerd.

There's nothing rude about wanting to understand a problem better
before donating free design consulting.

What's it for?

** Long time back I was offered a contract to design a small SMPS - not my specialty.
The spec was rather vague:
240VAC input, 5VDC out at 1amp and 0-120 VDC variable at 1amp.
The 120VDC to be controlled by a variable 0-5V input.

I wanted a lot more detail OR simply be informed what the task was so I could determine the missing parameters.
Got stone walled, no more info was forth coming and payment would only be on presentation of a working, usable prototype plus full documentation. This seemed very unprofessional to me so I pulled out.

Later info from the "middle man" involved was that it was some kind of medical device.
WTF !!!

Hi Mkr
the thing that stood out to me is you want to sense
" the output of an amateur radio xmtr when it's on the air."
and that means knowing that normal RF signal output
is being fed to the antenna. Anything else, is just an
indirect indication. Say, there was a short or other problem
that mimicked the appearance of normal operation, an
indirect sensing method would be fooled.

I seem to recall many years ago, a hobbyist magazine
project about stealing a little signal that leaked out
from imperfect shield of the coax cable. The pickup
was a wire wrapped around the outside of the coax.
One end, fed into diode+sensitive transistor stage, and on
to panel meter.

Unless you're using super-high shielded coax, I think it
might work.... cheers, RS
