    John Larkin furthers his claim to be our most out-of-touch-with-
    reality poster.

    I've never made any claim to be particularly expert with RF parts.
    I've certainly used wide-band transistors at frequencies close to
    1GHz, but strictly as wide-band amplifiers, and I'm aware that there
    are lots of fun aspects to their narrower-band use where I know very
    little - possibly even less than John Larkin.

    Don't feel bad, the other day I discovered that we have a tube of power
    mosfets 18 amps, 500V out of a batch we order with a different date code
    on them that does not pass the 500V break down test, they're good for
    only ~250v before they start to break down. These were purchased all at
    the same time but this particular tube seems to be older stock.

    Not only that, I notice the package, although the same type, looks
    like they were made else where on the planet, they don't seem to have
    the same exact mold shape. I wonder if I got rebranded or defective parts?

    It's not a bug deal, we just put those assigned with a note on them,
    they now are test fets, but these fets are not cheap and it's a good
    thing I didn't pay for them..

    I meant the small hook at the curves upper right extremity.

    I'd be curious to know what so obvious about these...

    Maybe they were shot down by those big companies that need expertise.
    HR takes one look at them and instantly determine they are 40 or
    older and kick them out as being "overqualified".
    The companies would rather hire two greenies fresh out of college and
    $$pend even more money in training for a year or so to get them to be
    useful..

    Absurd. It's just the opposite, in fact. Recent grads are living in
    mommy's basement, playing the XBox.

    It's the contrast between ill-informed fantasies and objective
    reality. The US electorate seems to have preferred the latter.

    It doesn't pay.

    A typo in the hand is worth two proofs in the bush.

    Can't blame the spreadsheet software.....

    Actually, Excel used efficiency as the dependant coordinate for
    drawing the line connection sequence. Efficiency should drop with
    over-exitation, if input drive power is included in total power
    consumed.

    There are valid bistable graphical plots, but this isn't one.

    You'd make a perfect politician, never getting the facts right and
    always twisting the truth, if you really knew what the truth was.

    ..here come de puns..
    Well, it was obvious as to the why and what, but the giraffe had its
    neck broken by the plodding idiot by interchanging the axis.
    Just rotate the giraffe 90 degrees so it will be standing on its legs
    and thus have no broken neck..

    Yea, yea, yea. Bot the presentation is absurd; rotate the graph 90
    degrees..

    It's been true for some time. It's hard for script-kiddies to find
    jobs. Experienced design engineers aren't having a lot of trouble
    finding work. While I have experienced some age discrimination, it's
    just as often been reverse.

    You've persuaded other people that at least some of the elderly should
    be discriminated against?

    I'd prefer that you hadn't gone to the trouble, particularly in your
    posts here.

    Find the fact I've got wrong.
    I've probably got a better idea of what is true and what isn't than
    you and John Larkin put together (and that's a depressing image).

    A sane person couldn't come to that conclusion with a dart.
    Slowman, NO ONE cares what you'd prefer. Really!
