You come across as a smart guy.

This is the best amateur radio forum on the internet, bar none. One
of the reasons it is so good is that it is apolitical. If someone
comes on the forum prattling on about how he works at a Christian
institution, and he can teach even though he is not qualified, and
how the education system in your country is paralyzed, these are
comments that have nothing to do with amateur radio. This is an
amateur radio forum. I would also add that evangelical Christianity
appears to be tearing your country apart, with its support for
pedophilia and sexual assault and racism re. Roy Moore, and I don’t
want to read about someone's support for Evangelical Christian
institutions or their Evangelical Christian beliefs on this forum.
Regardless of your country’s tolerance for unfettered free speech,
which gives you the idiocy of the Ku Klux Klan, Donald Trump, “alternative facts,”
Birtherism, and an incomprehensible belief and reliance on a Sky
Boss, or Flying Spaghetti Monster, or whatever else you want to call
it, this is an amateur radio forum, and It should be devoted to
amateur radio, and not an individual’s political or religious
beliefs,

Please keep your political/religious commentary off this forum. It
is not, as you should know, being a licensed amateur, appropriate
to discussions of amateur radio. You should know it, because it is
a condition of your license.

Thanks, Jack. I have been working at private, accredited

from colleges & industry to teach as long as they show "some
progress towards getting certified" as a high school teacher
with the ACSI. That’s quite easy, really.

I don’t have a teaching credential either, just a BSEE,
extensive MSEE course work and a MaEd.

Sadly the public school system is paralyzed with this thinking
that a teacher MUST have a teaching credential to teach. There
should be other ways to become a public school qualified teacher.

"properly qualified" to teach a HS class in IN. Maybe I
should try again, as I now live in OH.

Dennis is a wonderful person to work with. I know just enough

Jack, you are spot on. It is mission critical to get new hams
ACTIVE both on the air (including HF) and also to get them on
the road to get their hands dirty building hardware,
including antennas. The uBitx is a great way to do this that
I will use next month…see below. I ordered 8 of them and 8
plastic cases from BangGood.

I am a retired EE with over 30+ years experience in designing
hardware and radio systems from audio thru 40GHz. Teaching is
my new passion. I have been teaching ham courses (and how to
put science experiments on the ISS) at the high school level
for over seven years. My ham classes (disguised with the name
Satellite Tracking) is a high school level “science
elective” and I offer it over three semesters to allow
students to earn their Tech, General and Extra class
licenses. Doing it over a 4+ month period, for each level, I
actually get to TEACH the relevant material, have students
build stuff and get them on the air. They also learn a lot
about tracking satellites.

Every one of my new ham student “earns" an Alinco DJ-G7
triband HT and an Elk LPA Antenna to track satellites if
they pass the Tech exam. They also build an EggBeater antenna
I designed and presented at recent Pacificon events,

Next Semester they will each build one of the uBitx
transceivers and a 40M dipole and they WILL get on HF!

BTW, Jack, we have a mutually close friend, Dennis -W6DQ, I
manage the Collins Collectors Association West Coast Friday
night NET on 3895 at 7PM. He is one of my NET control
operators for that net!

Thanks for all you do for our Ham Radio hobby and, of course,
your contributions to this uBitx, etc.

I changed the topic to narrow the focus. You're right, Joe,
the social media sites have a lock on young people. My club
gives the FCC exams every month (except Dec.) for free and
we always have people show up; sometimes as many as three
dozen. Most are going for the Tech license to get their toe
wet. Then they buy a 2M HT and we never see them again. I
did run into one guy almost a year later and asked how he
was enjoying his license. He said: "I haven't done anything
for the past several months. It doesn't even let me do what
my cell phone does." We need to get Tech's more than just a
small slice of 10M in the HF spectrum. Otherwise, I think
they are missing out on 90% of what ham radio has to offer.
When I was a Novice, we had small chunks of HF (e.g., 40M)
to play with. True, you were rock-bound and limited to 75W
and CW, but I spent almost all of my time on 40M. Britain
has had more success than we have with young people, and I
think part of the reason is because they give their
Tech-equivalent hams small slices of spectrum on all bands,
including HF. They are limited to 5W, but at least they can
chase DX. Other than the rare atmospheric events, DX on 2M
is a couple of counties away with the HT that most end up
buying.

I look around at my club and I can almost hear the arteries
calcifying. I can say that 'cuz I'm two years younger than
dirt so I know the aging membership issues quite well. We
need some younger members; perhaps younger than those who
are recently married and starting their families. The real
solution: I don't know, but there are things we can do. I
have a FB account, but probably use it twice a year. I'm not
on Twitter. I need to root around there for a while and see
what I can do for the cause.

Ok... I measured voltage. From supply negative to heat sink, I have 12 volts. From supply negative to IRF510 source (rightmost leg) I don't measure anything. The heatsink is isolated from the chassis.

Yes, you are supposed to be able to adjust the idle with that RV1 I was talking about. It does nothing

The PA voltage is going through the switch as well. I measured from the DC plug to the base of the positive that feeds the PA. It does double when I click PTT, but that's it. I'm set on 200ma so I'm assuming I'm getting like 5.6 - 5.8 milliamps through it when I press PTT and 2.6-2.8 just idle

I followed the directions exactly. I know the oddity you're speaking of.
The brown wire from the raduino connects to black on the board and the
brown wire from the board connects to red. I did that correctly.



Yes. It's a Bitx40.

Also at 2 feet from the receiving rig, the dummy load is sufficient. No
need for an antenna.

With the antenna, do you receive anything on the BitX?

Vince.

No. I didn't hear anything, but the antenna was on the floor. I tuned my
HF rig to a really strong signal and tried to find it using the Bitx40
but it never picked anything up.

I'm very distressed right now. My 9 year old asked for one for Chanukah
built inside a lunchbox. She studied and got her general just so she
could have it. She's worked really hard and I've already given her an
antenna and coax. Then, today I finished the build, and tried to test
it.... and it failed.

Ok. I had built it with a buck converter (I think is what they're
called) to turn 12v into 24 volts. So, the first thing I did was to turn
RV1 all the way down. I hooked up a cable and a dummy load into the
cable. I set my meter on 200ma. I measured from the DC plug to the
on/off switch. I got 2.8 I think it was...it doubled when I clicked PTT.
I tried measuring voltage from the dummy load and got nothing. I took
the buck converter out of the circuit where it was powering the final.
With 12 volts powering the final, no change. I tried adjusting both RV1
and RV136. No change. I tried tuning it to a frequency, tuning my HF rig
to the same frequency, hooking up an actual antenna (laying on the
wooden floor though) and transmitting. Didn't hear anything in the HF
rig two feet away.

I had a computer mic hooked up as the mic. Tried saying hello in it
loudly...nothing. I wired up the electret mic that came with the kit.
Nothing in it either. When I push the PTT, I hear a click from the radio
and it does double (milli amps?), but that's it.

Works even with five. I left the usb cable connected From the pc and switched off the dc suppy. Kill me, but it continued to receive at low volume.

Have you looked at threaded inserts?? Think of a pipe nipple that is threaded internally and externally.

There are several brands.? This is the first one I found.? If you have a real hardware store with aisles full of bins and trays of weird fasteners you might find some you can actually put your hands on and find nuts and washers and bolts that work.
