As of sometime yesterday, 02/08/2016, I was granted my Amateur Radio
License with General privileges.
Thank you to everyone who had a hand in making this possible. I am
quite happy and yes, a little proud, too.
In just a few hours, I will take possession of my Elecraft K3s and P3
components.
I have two super selfless, super-experienced, super-patient operators
who've taken an interest in me.
And I have TWO local clubs available to me from whose members I can
learn and through which I can contribute to the hobby and my community.
My cup truly runneth over... Thank you, Lord!

Hi Bob McGraw,
I agree, except on one point: I’s say 90%, rather than 75%, of the stuff we use
and methods employed would put most of the station stuff in the trash.

Since the assembly of coax wound around a toroid doughnut style bobbin is
typically not exposed to vibration, such as might exist in an airplane, boat or
space vehicle, the use of a solid conductor coax such as RG-303 would not seem
to be of concern. The more important point and my experience and as related by
others, the use of coax which has foam dielectric in a tight radius bend has
been proven or shown to be problematic. As to if the manufactures bending
radius dimension is being violated, I find to be of little concern.
After all, as a rule, hams are noted for pushing things to the limit and then some and
getting buy with it. If hams choose to "stick to the rules 100% in all aspects of
their stations"............I'd say 75% of the stuff we use and methods employed
would put most of the station stuff in the trash.

Hi Bob, et al,
Thank you all for your careful attention.
I read it wrong, as several have pointed out overnight. I transposed that
to a percentage in my memory after reading it. One of the reasons for
referring people to the original material in these cases. Someone will get
it right.
That makes it two and a half hairs :>) Doesn't appear to change the
argument. To me anyway the method is still a crude measurement instead of
watching a wide frequency scan while bending the cable along with other
performance specific measurements.
I still would not use the solid center conductor versions (RG142/303) on a
winding.

Hi Guy,
I am not sure how you arrived at the “2/1000 of an inch” figure from the
ANSI spec? The spec actually says “A change in ovality from a given
sample’s initial measured value of 0.010 inches or more (> 0.010)
represents the point of non-acceptable bending performance.”

I also suggest that everyone carefully study the ANSI standard until it is
clear what they are doing mechanically and see what they are actually
measuring:
http://www.scte.org/documents/pdf/standards/ANSI_SCTE%2039%202007.pdf
The method of measuring is in section 4. They are looking for a limit of
1% surface deformity when bending.
In the case of RG400 with .195 inch OD, that would be 2/1000 of an inch
(yes, that's three zeros, two one thousandths of an inch) bending deformity
at the surface of the teflon jacket, or half the thickness of an average
human hair.
