    I am reading an avionics book this period.
    My question is why the signal generators and receivers have a standard
    impedance of 50 ohm.
    Thank you

    After a short search, I found a few lines from Phil working out his anger
    issues;

    How vague is this functionally illiterate Brisbane ****,

    RF stands for Rabid Fuckwit.

    Beware Fuckwit - the cops can get your home address from you ISP in
    about ten minutes.

    See, you dumb ****%^&%#^*^

    One of us it the autistic toaster-boy from Summer Hill - so is the
    other one. So go **** yourself!!!!!!!!!??????!!!!!!!!!!

    You get my pompous, ignorant ass award

    Go eat your own droppings - Grease Monkey

    An honest debate is out of the question for those with only ape like
    IQs

    Then let the maggots eat you

    This vile HT knuckle dragger must have one arm longer than the other.
    He keeps going round in ever smaller circles.

    But all here can see it - you asinine, autistic ****.

    Now ***Piss off *** - you asinine FUCKING LIAR !!!!

    Now go eat shit - mutherfucker !!!

    Just proves you're a bigger fuckwit than we already thought.

    No fucking " idiot savant - Rain Man " here - just a deviate, fuckwit
    ****.
    Learn to read - fuckhed.

    Morgan is a pig ignorant POS .

    A typical brain dead recording engineer

    Note: this was a short, and is in no way meant to represent all of Phil's
    anger issues.
     

  6. Because 50 ohm coax has the best power transfer characteristics.

    Thanks for the summary. I've had PA in my killfile for ages and kinda
    miss reading the big lunk's opinions, in a strange, perverted way
    (much like, well, let's not go there). Actually amusing when they're
    collected together like that.

    Thinking about it, a "Best of PA" would make a dandy cookie file,
    wouldn't it? Hmmm... where'd I leave my google...

    ** How does taking lines out of NG posts with no context prove anything ??

    Of course, it doesn't.

    You a must be a congenital moron to think it does.

    An " AM band DXer " is just about right.

  10. It would be interesting to see his archive after it want through a
    filter to remove his favorite words and phrases. It might be a whole 20
    KB file.
