Re: OT: The Colpitts mystery

I took my Tech and Advanced tests in Portland. I think I took the 13WPM
twice before I passed. I also failed my 2nd Class Radiotelephone license
(it was free and I didn't study enough and I failed by two questions). I
remember the main guy was George Wager, and there was a woman named
Sheryl who worked there who was exceptionally attractive. They were all
scary, but they were also all very nice.

Re: OT: The Colpitts mystery

Edward R Cole
In reply to this post by k6dgw
I guess a lot of us took the Commercial Radiotelephone License.

I got my Novice and Technician License by my mentor.  That was the
General Class written exam back then.  Tried several times to pass my
General CW test at the Detroit FCC office (we lived 70-miles away so
not qualified for a Conditional).  By 1962 I was an EE student in
college with no time for upgrading (or any ham radio).

In 1971 I was laid off from Hughes Aircraft along with thousands of
other engineers so my job prospects were bleak.  I decided to take my
2nd Class license to qualify for work for radio or TV broadcast.  The
theory exam was twice as tough as the Extra in my opinion.

In 1982, I found a job working in marine electronics so pricked up
the Radar Endorsement.  I also passed my Advanced in 1982 at the
Anchorage FCC.  CW test had been downgraded to a multiple question
exam about plain language text message vs the five mixed character
groups back in Detroit.  Yeah those Detroit FCC guys could have
passed as FBI guys.

In 1983 my 2nd class finally netted me a job as engineer for KYUK-TV
in Bethel, AK (I flew out to into the bush to repair the TV
translator network).

Wasn't until 2000 did I pass the Extra (downgraded to 13wpm).  Missed
two questions on the written exam (because I knew more than the test
designers and many of the answers were incorrect).

The ham CW test was always plain language text.  5-character groups were
only for the Radiotelegraph CW exams.

Re: OT: The Colpitts mystery

In reply to this post by Nr4c
Probably not Bill since it has drifted way off original topic and
continues to do so.  I posed the original question.  My guess is that
the Colpitts oscillator was probably the easiest to get stable [or
nearly so] of the extant designs then because it uses capacitive
feedback.  It would be the most familiar to examinees and the FCC just
settled on it.  I remember that some only had to draw the schematic,
others [including me] had to complete a partial schematic and answer
questions.

Incidentally, Colpitts was also on my 1P and 2T exams.  Since the only
copier then was Thermofax, once they had a question set about it, they
probably just stuck to it.

New Mystery: Copying groups vs plain language text

k6dgw
In reply to this post by Phil Kane-2
Why were code tests with groups almost always at a slower speed than
plain text?

I had to copy 5-character groups at 16 [I think], and plain text at 20
[I also think ... might have been 25, it was a very long time ago] for
the 2nd Telegraph.  I've never sat a military circuit to copy groups,
all my experience with groups was practice, the test, and WX reports
which sort of approximate groups.  However, I find groups to be easier
copy than plain text, especially on a mill of teletype tape perforator
keyboard.  The transition to "Ear-to-Fingers" mode with nothing passing
through brain is almost instantaneous and permanent for the duration.
With plain language text, I'll sometimes rouse from that state, try to
make sense of what I'm copying and have to catch up.

Just curious, lots of folks here here have copied groups for a living
and might know the answer.  Incidentally, Jettie Hill, W6RFF [SK], once
told me that in WW2, he had to learn to sight-read inked tape at 45 or
50 WPM.  I think that would have caged my eyeballs. [:=)

I did all the FCC required licenses at Portland FCC.  General class while in High School, all commercial licenses including 3rd class radiotelegraph and Amateur Extra around early 1960s.  And with a 10 year broadcasting career usually yearly visits from McCann or another FCC engineer Burson at the broadcast station inspections.

Frank McCann was one of the old timers when I joined the agency in 1967.
 By that time he was the Engineer in Charge of the Portland Office but
the EIC did a lot of the journeyman jobs in those smaller offices.  When
he retired in the late 1970s (or was it the early 1980s) I applied for
his job but they had to give it to someone else whose office was being
closed and I continued at the San Francisco Office until I retired in
1995.  I have no idea what happened to him after that.

I took my novice test when I was 11 years old from W1ZWG at his home.
This was the summer of 1958 and I believe that any General class or
above could give a test for Novice and Technician class licenses.

Re: OT: The Colpitts mystery

Bill Steffey NY9H
why have an engineer on staff ???    just shop a few services out for
the best price.

When I got my First Phone I thought I could find great job security ....
but I twisted from broadcasting to sales....on the way home from my
first interview with WAAF/WGRT I took a job in the audio industry...a
career that lasted 40+ years.

and when they wanted my P1 ticket to give me GROL I took a pass, as I
was NOT going to give that up.

I took my Novice exam from another ham in 1972, but my general and advanced
at the FCC in 1977 or 1978.

Not exactly.  The FCC started the  Alternate Broadcast Inspection
Program (ABIT)  about the time that I retired from the FCC. in the mid
1990s when there was a push to privatize Federal agency obligations  to
some extent.  The FCC did it for broadcast station inspections, ship
station safety inspections, and resolution of harmful interference.

ABIT is a voluntary program under the management of the various state
broadcasters' associations that contract with individuals to make
compliance inspections of broadcast stations.  The station pays the
association a fixed fee, and the association pays the inspector.  I
contracted with the California association from 1996 until 1999 and
traveled all over the state.

Notification of passing an ABIT inspection was sent to the FCC but
failures were not so reported.  I don't know if that is still done.
Such passing was regarded as "insulation" from FCC inspection for three
years but the FCC still has the obligation to inspect broadcast stations
both on a random basis for compliance with specific programs such as
tower lighting and EAS compliance or if a complaint has been filed that
bears on rule compliance, technical and otherwise.  --

So you wound up with nothing when your P1 expired versus keeping the
same privileges with a GROL which soon became a lifetime license.  PS -
you would have been able to keep the P1 certificate as a "souvenir".

We all have similar stories, sad part is, there are extra class licensees
that dont know any more  about oscillators than ohms law or caculating the
length of a half wave dipole.

The ones to "tell the tell" ain't gonna be around forever, few of us left,
ain't no more coming over.

The barrier to entry certainly isn’t what it used to be, but that’s probably a good thing. If someone gets on the air and has fun (even FT8 hihi), I really don’t care if they can recite Ohm’s law or not. When they are interested, it’s as easy as picking up a copy of the ARRL Handbook. Doesn’t have to be an oral tradition. As long as I can call CQ and get an answer, things aren’t too bad!

Re: OT: The Colpitts mystery

Elecraft mailing list
I once spent 15+ years racing bicycles, officiating and promoting races.
During the same period lots of bikers tried their hand at building bike
frames. This required design, fabricating brazing jigs, and the actual
torch work. A few became known builders while most just gave it up as
too complex and demanding. All, I assume, continued to ride and race.
Moral of this story is that one doesn't need to know how to build a bike
frame from scratch in order to enjoy biking. Most racers [the 40+ wpm
contest folks...?] then and now couldn't tell you very much about bike
frames other than "fit, doesn't fit." Same with cars. My father used to
say that "back in the old days" you worked on your car all day Saturday
in order to take the family on a Sunday ride. Try that with today's
cars. So, perhaps the same goes with radio electronics and ham radio
builders and circuit designers. Once, you had to build your own to get
on the air. However, other than fun, does anyone here want to do a
contest on a crystal set? Probably not. The trade off seems to be
between simple and limited versus complex and limitless. The info is
there for those who have and/or develop a keen interest in electronics.
The rest can appreciate the wonder of it all while enjoying the "front
panel" of their radios in their daily QSO's. ...IMHO
