Re: Voltage drop in DC Power to K3

Charlie T, K3ICH
From the wire tables, I think you'll find that doubling the number of wires
will result in an equivalent of one cable 3 wire sizes larger.

That is, two #18 wires equals one #15 ( and yes, I KNOW there isn't any #15
wire easily available).
Likewise, two #12 wires is the same as one #9.
So, from this, the hassle of using two #12 wires is only slightly better
than one #10, but not quite as good as one #8.

Obviously, every installation may be unique, so use the largest you're
comfortable with.

Yep.

And I've also used W1ZR's solution of two of the same size cables in
parallel.

Yep. It was one of several we had to learn. :)

Because most instrumentation available to hams isn't accurate enough.

OT: The Colpitts mystery

k6dgw
In reply to this post by N4ZR
What was it with the FCC and the Colpitts oscillator schematic on the
exams in the 50's/early 60's?  It was on my General ['54] and Extra
['56] exams, and practically everyone else I've asked says it was on
theirs too.  There are other oscillator circuits of the day.  Colpitts
uses capacitive feedback which is somewhat more stable than a Hartley
with its "Tickler Coil," but the FCC seemed fixated on the Colpitts for
some reason.  The schematic and operation of a dual-triode 1-shot was
also popular.

Yep. Three wire gauges is double the cross sectional area.

In reply to this post by k6dgw

The Colpitts oscillator was regarded as being the most stable
oscillator, which is why it probably was always there, and it was indeed
on my test in the mid-60's.  But the Hartley oscillator was also on my
test if I remember correctly, as was the tuned-plate tuned grid
oscillator.  If I remember correctly, I had to identify each of at least
three oscillator types.  The series tuned Colpitts (aka Clapp
oscillator) might have been there ... maybe the Pierce crystal
oscillator also.  I remember that I was required to be able to tell a
bunch of them apart.

Mine was the push-pull triode RF amplifier (not "linear"!), making sure
to show the neutralization circuit. They didn't want any high-powered
self-excited oscillators on the bands!

It was on the 2nd phone as well!
Not sure if it was one I had to draw or just identify.

My recollection is that the 2nd phone was much much harder than the present
Extra.
My commercial licenses were 1959. My Ham license is 2007.

They had to pick one of the two, and the rest was inertia.

The Second Telegraph exam that I took about 8 years ago had the same
questions as the one that you took "back when".  Who remembers
"transconductance"  :)

I would imagine that a lot of people still know what transconductance
is.  That's how FETs work ... voltage control of current.

Umm... there were three main oscillator types when I was first learning
electronics. Colpitts, Hartley, and Armstrong.

As a 17 year old, I rode the train {pulled by a coal fired locomotive}
from Fulton, KY to Memphis, TN.  I had to walk about 8 blocks to the
Post Office building where the FCC administered the tests.  I took the 4
elements and passed all 4 of them earning me a First Class Radio
Telephone license on the first try.  I recall many much older folks
seemingly to be struggling to take the tests.  Some commented "what's
this kid doing in here?"  Seems some had taken it several times without
success.     I spent the night with an old maid school teacher and
relative in Memphis.  I took my General class license test the next
morning in the same place.     The CW receiving portion, in the concrete
basement with metal desks and metal chairs, sounded like marbles being
dropped into a galvanized wash tub.   So was that a T followed by an E
or was that and H?  Passed that one too.  Then I rode the bus from
Memphis back to my home in Martin TN.  Yes there were several circuits
to identify, and some to draw, as I recall.   That was 60 years ago. 
Glad I had the experiences.

Re: OT: The Colpitts mystery

While in college, I co-oped with the FCC in Atlanta, GA. I had to take
and pass my Radiotelephone First and General class licenses before I was
allowed to administer those exams. If you did not pass a test you had to
wait 30 days before you could take it again. Some applicants tried to
game the system by memorizing as many questions as they could when they
first took the test so it would give them a leg up the next time. On the
second attempt there were usually howls of anguish when they realized
they were facing a different version of the test with different questions.

While I was taking the Advanced written test the phone in the room rang. The test administrator picked it up, listened a bit. Then a look of disgust appeared on his face. Then he lowered the phone, looked around the room and asked "HAS ANYBODY SEEN A BASH BOOK HERE?"  We all grinned back at him and shook our heads.He picked the phone back up said " no one has seen your Bash book" hung up the phone and we continued with our exams.Sent from my Verizon, Samsung Galaxy smartphone

The FCC question pool was always published by the Government Printing
Office. There were no answers though. All the study guides of the day
were based on that pool including the ARRL License Manual.

Except for the Novice exam, I took General (Boston), Advanced and Extra
(Long Beach) at FCC offices. When I took the Novice exam in 1957, my dad
was Exec Officer for the 4th Regimental Combat Team at Fort Devens, MA.
He found a PFC/ham within the ranks who administered the code exam. The
PFC was shaking more than I was. I don't think he wanted to fail me.
They were on bivouac at the time so I took it in the guy's squad tent
sitting on his locker with a J-38 strapped to my leg. FCC field offices
were nicer.

Originally question pool was not published. The people who taught quickie courses and published exam guides did not have licenses they would take exam, fail it and report new questions.

Re: OT: The Colpitts mystery

In reply to this post by John Simmons
The time of which I speak was in the mid-1950s. As I vaguely remember
there was study material that prepared you to be a knowledgeable ham.
There was also a big book that prepared you technically to be a radio
station engineer. At a later time there was a one-day cram course to
prepare you for the exam for first phone. Before my time if you had a
radiotelephone certificate you had to have a certain amount of
experience working at a commercial station in order to renew your license.

I got my Novice in 1972 in Boise Idaho. I don’t remember if there was an
FCC office there. Would they have gone to other cities to administer exams,
or did they have VE’s by then? My dad and I both tested together.
