Hi Jack, As you may know I have ordered 8 of the new UBITX transceivers and I’m excited they will arrive tomorrow. These will be used in my high school ham class as a project for each student in

From the wire-up instructions: ????????If you are using a non-metallic box, solder wires between the ground lug of each of the sockets and connect it to the DC ground. Not sure if this

I am reading this thread with great interest as I get my mind around diving into my bitx40 to try and get it working again. It worked when I last used it (at least I think it was working) one never

Grounding! Dummy 1 was not grounded. Dummy 2 is part of the antenna switch system that is well grounded. When I attached the uBitx to a battery dummy 2 read the same as dummy 1. Now - next mystery -

This process is also wonderful for those of us without a lot of troubleshooting knowledge. ?I've very much enjoyed following this thread and have been taking notes.? My bitx40 is in the box waiting

Dr. Jack, I have a blog post to help procrastinators, it the purpose behind this little plexiglass platform, I call a workstation. Just Build it….then twiddle it, then tear it apart, then put it

While I applaud the Arduino IDE and run-time library for 1. largely insulating the user from the microprocessor architecture (what reg bits go to what pin, how to run timers, etc), and 2. ease of

Arvo, I really haven’t explained it, but since I have been right here a few days and likely will be another few….so be it…we are where we are…that is what I was doing… have to run and

Sadly during the long night and early morning 2 Mega Pros and 1 I2C 4x20 LCDs gave their Lives until I figured out a wiring error on the Raduino header on uBit Main Radio PCB. Rip $$$ I 3D printed

Hi Craig: I have been messing around with where I want to place the controls for over a week! Come on, Jack, just git-er done! I'm going to start drilling/cutting today! I'm going to make a capacitive

I'm by no means a professional programmer just a retired old business analyst who had to do some programming along the way.?? I started playing with Arduinos when I saw the article for Jack's

Is it just me, Craig, or are you in the hospital? Apologies if you've already explained this.

Thank Dr. Jack, I had four Antenna Analyzer boards, we built two, so some kind of way two are available, and we have two built two different ways to show. I have a forty niner kit in a bag that I

Thanks for the reply. My concerns/puzzles/WTF: My trusty old MFJ 259B antenna meter at 7.1 MHz says ???????????????? real? imaginary? SWR dummy 1?? ? 50?????

Do you bring all three clocks to the connectors? Vince.

Jack, that might already be possible, but requires some new hardware and some hardware hacking: The problem is that you are running the code not on your host computer, but on?the Arduino, so you need

Mike, do you have a web page that lists what you are selling?? -- Karl Heinz - K5KHK

I don't have any of the AA boards (Nov., QST) as they all went to QRPGuys. Given what I sold before the article and what's been sold since, it's closing in on a thousand boards. I will bring the B40

?Remember to keep it simple for us dumb bunnies who are NOT professional programmers and last did any REAL c programmming 2 decades ago. I was delighted that the system made it easy for me to see
