Re: ?BITX as a Tool for Recruiting New Hams
If you want to attract a crowd (including the police!) go to a park, put up a portable antenna (mag loop, Buddipole, even a Hamstick), set up your radio with a battery or small (10W) solar panel, and start calling CQ. People are naturally curious when they see this. If you want a larger crowd, tell them you work for the gov't but can't tell them any more than that or you'd have to kill them.

Re: ?BITX as a Tool for Recruiting New Hams
I thought I should have a radio in case of emergencies.? Then I thought about scale of emergencies, so I thought of SW.? But hams are working some emergencies so being able to listen to HF SSB would be good.? And if I'm in that big of an emergency then being able to talk would be better.
Back in the early 70s I'd run into a Heathkit catalog and saw the ham rigs.? I built their code oscillator to learn code, but never followed through.? A friend of my dad gave me an ARRL handbook.? That was always in the back of my mind.
Fast forward the emergency radio thoughts, and how big of an emergency.? I looked into getting my ticket, and after some online study passed my general about a year ago.? Got a cheapo HT and figured out how to use the local 2M repeater and did some rag chewing with locals.
I kept poking around the internet looking for ways to get on HF without spending a lot of money.? (Our first grandchildren have also arrived in the last couple of years, and they are another expensive hobby.)? CW can be done on the cheap, but I still haven't (I know!) learned code.? The BItX40 fit the bill very nicely; I didn't want to spend a lot of time building something.? I also found SDR, which feels like having one of those vans with five guys in the back looking for Jason Bourne.? So when the ?BitX came available, much to my surprise as I was thinking it would be another six to twelve months out, it pretty much filled out my basic wants.? Of course I still need to learn code, figure out the digital modes, build antennas, hack at hardware, learn Arduino/Raspberry code, and so on.? It'll keep my curiosity engaged for a long time.
Plus I get to interact with a new bunch of very interesting people.
PS? Don't get me started on the sorry state of mathematics education.

Re: ?BITX as a Tool for Recruiting New Hams
All good points. When Sandy hit the East coast, ham radio was the only thing working for hundreds of miles. The cell towers were either down or non-functioning. A ?BITX, my 20000mAhr Li-ion battery pack, and a hunk of wire and I'm more valuable than AT&T.

Greetings!
Would the 100pF cap added to the LPF work on the BITX40 model.
I just wired up the BITX40 kit I received two weeks ago and there was an extra smt cap in the bag of parts.?
It was not listed in the assembly pages on-line.? I have not yet found how that was to be used or if it was needed for
some other mod or update.

Re: ?BITX as a Tool for Recruiting New Hams
Stephen
Thanks for sharing your insights.?
My 2 cents worth. I'm in my 50s, with young kids at home. Just passed my license exam thanks to some encouragement from W8TEE.?
Foremost, younger folks don't use voice much at all. Text, Facebook, email or video chat. Since that's what people like, that's the direction ham radio has to go if it is to grow.?
Honestly I'm little interested in voice myself. Digital modes are ok, but not too exciting because they are so limited. I keep learning and trying new stuff.?
What really interests me and my kids is telecommand and telemetry. They are useful tool. Scant little is available to novices like me. So my few past projects are more failure than success. ?I have a pile of microcontrollers that lost their magic smoke.?
On Google. You get the results because of search engine optimization. ARRL and others pay to rank high in the results. A private user has to get a lot of traffic to overcome it.?
Outreach has to center on topics of interest. Like email without internet, etc. Video tutorials are popular with lots of people (tho I prefer written instructions with photo illustrations).?
I like the hobby a lot. My boys like to "help" make things like antenna and little circuits from Jacks book. I hope it encourages them to learn and explore.?
Lists like this are useful for novice learners. Thanks to all who contribute.?
I would like to know what books are best for telecommand and telemetry experiments.?
In closing up a random post I'll just summarize that I tell my boys and friends that radio is what makes most of our modern conveniences work, so it's fun to learn and build stuff. Parts aren't terribly expensive so it's good entertainment.?

Re: ?BITX as a Tool for Recruiting New Hams
That's how I got started...a cub scout visit to a local ham, Chuck Zeigler, W8FTQ (I think?). He became my Elmer and I became his pest, hanging out at his home anytime I could. He gave me my Novice test in 1954 and I've been licensed ever since. He also helped me build my first transmitter; a 2-tube affair with 15W. Without his efforts, I don't know if I'd be a ham today.
I just wish I new a sure-fire way to capture those people like your friends who never get pushed over the edge.

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.

The dummy load my group (Greater Cincinnati Builders Group) built used mineral oil, which is non-toxic. We tested the DL with a 200W signal for 5 minutes without failure of any components, although the mineral oil could probably do French fries. A construction article on the DL has been accepted by QST, but no projection on the date of publication yet. This shows the top of the DL. The cost is under $20.

Mine was shipped on the 12th and arrived on the 14th. Paid for DHL with tracking but never got to check tracking. As a kid every thing I ever ordered came parcel post and took 3 to 4 weeks to arrive. BTW I can't wait to get it in the air. Many thanks to the HFSignals staff.? ?Steve kb1chu?
Sent from my Smart Phone I said I'd never get.

Re: ?BITX as a Tool for Recruiting New Hams
Werner:
That is so cool! I checked with a local high school when I was in Indiana about teaching a ham radio class as part of the STEM system. Even though I have a Ph.D. and 40 years of university teaching, I was told by the Principal I was not "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 EE stuff to make him tear his hair out when I ask a question. Still, he has the patience of Job and can always frame an answer I can understand...and that's a real talent!
Thanks for this email...maybe I can fool some OH administrators into letting me in the classroom.

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.

Re: BITX40 - frequency spectrum - Raduino irradiation - intermodulation products -
#bitx40help
@N8DAH: partial success: the harmonics are now < 55dBm - unfortunately the IRFs are still there.
When i reduce VFO-Driver current with a resistor (2,5k) the IRFs will disappear - but also the receivers sensitivity and the max. power lost 3dBm.
