of course. i prefer the nice safe plain text, but i guess not everyone sees
it that way.

Hi All,

Not everyone sees in HTML either, and getting drenched by all of those
superfluous mark up script tags doesn't add to the conversation.

Outlook has a horrible reputation for launching insecure processes and
for spreading virus through marked up pages - no one knows the risk
offered by the content of any post until they open it. I use Agent
which has a safe HTML renderer, but I still don't need someone's
infected posting sitting in the thread.

The addition of charts, graphs and pictures could be put to good use
here. It "might" even bring sense to contrary current flow of
gaussian vector particels. In that sense, HTML would be a virtue;
however that isn't the convention of an already established text-based
group. (And the counter graphics of contrary current flow "might"
bring a blush to the easily offended.)

But if we went fully marked-up - what new vistas for rhetorical
exploration would be found there! ....and it still wouldn't solve
anything.

You might be surprised just how much level you can
get from a tuned small loop on the low bands.
As an example, that 16 inch loop provides more
signal than the whip on a car. I once tried it with a
delco radio in my truck. I hooked the loop up to it,
and it was as hot as a firecracker vs the standard
whip.
The catch is the system is very high Q, and requires
constant tuning of the cap as you change frequency.

That bites you when you use resonant loops. Of course non-resonant
loops don't have nearly the effective performance. Initial
selectivity to reduce the noise bandwidth before amplification or
mixing is why it is so common.


I recall medium-size table radios having a loop antenna in/on the back
cover. I don't know whether there was also a ferrite rod inside.

We'd have smiley-faces and frowney faces. That would be good ... wouldn't
it? (Just kidding. No brickbats, please.)

There was not one in the clock radio that i grew up with. I know, i
had it apart by the time i was ten.

Say Chris, how about you set your Outhouse Express news/mail client to
use a quote character. It is good manners in news groups.


Joseph, please explain (and excuse my bad manners!) - use a quote
character
for what?

Are you referring to my use of the pairs of single quotation marks 'xxx'
in
what I'd written? I usually reserve double quotation marks "qqq" for
actual
quotations; things that people have said ... but I suspect you're
referring
to something else.

Hi Chris,
I need a bit more with respect to your response in more layman terms

When a multi turn helix is generated it can be used for both
transmitting and receiving.
When generating two helix antennas where one is contra wound and both
are connected at the top
you are saying that it will NOT be suitable for receiving !
We know by common use that the single helix is good for transmitt and
receive . So what exactly
does the addition of the contra winding do to prevent the combination
from receiving?
Looking forward to your take on the question.
Best regards
Art


OK. The term 'helix' is most often applied to the travelling-wave
antenna
invented by John Kraus, often used at VHF and above, which generates or
receives a circularly-polarised wave predominantly in the direction of
its
axis. It is also used in 'normal-mode helix' for the type of monopole
element often found on walkie talkies, that generates and receives a
linearly-polarised wave. Both of these are connected to electronics at
one
end only.


This sample, directly above, shows no distinction between your writing
and the post you responded to. I pointed this out last week in
another thread. However, at the top of this post above the starred
line, you clearly follow quoting conventions.

I have the 'Plain Text Settings' option 'Indent the original text with
when replying or forwarding' ticked in OE and I can't account for why it
isn't working. I guess an incomplete sequence of cascaded s could
make the historical record difficult to follow. I wonder if this has
happened when I have snipped the accumulated message trail.

Chris


its not your fault. some news senders, like art, send in a format that oe
can't figure out how to indent and . i have tried lots of combinations
and the only one that works is to send in html format with the vertical
bar quoting.

Thank you for that ... and I gather some get equally irritated about people
sending HTML.

Chris

I am not so sure that is only OE having a bad reaction to some other
non-conforming news reader. Just the same i can easily see OE getting
confused by a non-conforming news post more easily than any other news
client.

Most 5 tube All-Americans had a loop glued inside the Masonite back
cover. Fewer had a loopstick.
