Hello Ken. I checked out your web page. Saw the case makings of yours? for the Tut Hill on one of your project pages. Nice. I have two of these radios collected. One with the factory case - 80M. The other I aim to build it's case custom. Even as far as the symbols, too generic. Looking at your fabricated ubitx enclosure, could you tell me how to avoid such a gap - snag - in your upper right corner of the lid? I, myself would have trouble living with that. Case building is but one aspect of amature radio, and not always the objective, pursuant of. Neither, is it necessarily,? a "case" of agony to display. Sometime, though, all I am interested in is the enclosure, and the accommodations needed to consider, in?design,?for the circuitry inside.

?This paragraph of yours was in the page presentation.....??

"Making your projects look presentable, is not an absolute necessity. Some even prefer the rustic look of their projects and see it as a “red badge of courage”, showing the agony of their efforts. After all, scotch tape and a penciled label can? identify just about anything, or merely writing on the chassis. Having said that, there is a very small group of hams that like to see their projects look like they were done on purpose. I will try to address that group".

Thank you for the tips. I cut with a most ancient tool, but sharpest edge available. Be that obsidian. Great joy in crafting something with one's own imagination, every now and then - a must.

Ahh. New sw thats the resolution to my problem!!! Did manage te do something via cat with the original sw but got strange errors on uBitx. Cant wait

You almost certainly have your tuning pot wired up wrong.
Wires into the pot include 5v, ground, and the wiper goes into a Raduino analog input pin.
You likely have the wiper wired up to 5v.
When the pot is turned such that the wiper is close to ground, the resistance approaches 0 ohms and current approaches infinite.
(Alternately, you have the wiper wired up to ground, and it smokes when you turn the wiper close to 5v.)

Probably time to order a new pot, though it might still sort of work.
Check the pot out with your ohmmeter before soldering it up, make sure you understand how it works.

You must be shorting a power line thru your Pot?? Pot draws lots of current, smokes, and PS current limits.

Don't keep doing it.? BitX is too Young to Smoke!

Hello World!

I just wired my BitX40 and was ready to test out the receive. everything seemed right, LCD show the freq. and there was sound. when I tune the dial up, it goes up, then I tune down, seems good. Except, one the dial hit the low end, the dial started smoking and the radio power fluxed. I quickly removed power, double checked wiring, and tried it again. Same result. Once I hit the low end of dial, smoke from dial. Any ideas? I know basic electronics and nowhere near competent levels ;-) Any advice?

Thanks de K0KIK

How many times does a BitX40 that you had a Sunday nite QSO with drop in on your bench?



All of these will be on display in Morristown TN next week.

I have a suggestion when someone suggests a vendor.? The idea came to me when Vince found a 1/4" shaft audio pot (great find by the way).

Just heard back from Adafruit. This pot: for $1.50 is an audio taper and has a 6mm shaft (1/4" is 6.35mm).

I've never ordered from adafruit because for the longest time they wouldn't ship usps to me so the shipping was a killer.? I see they finally will ship usps.?? What else should I buy from them?? I'm not talking about the standards I can find anywhere but it seems like each vendor has a few things that are very difficult to source anywhere else.? An example would be the M7 nuts for the chinese encoders that Jameco seems to have the market cornered on.? Like most of us I have paid more in shipping than the part costs just to get something I need only to remember a day later I should have ordered something else or spent more time filling my cart on Tayda to hit $5 than it took to find what I was looking for in the first place.? So my suggestion is this, if you are naming a vendor try to also list a few things that are great cart fillers or hard to find anywhere else.? I realize with everyone chasing different projects this isn't always practical or useful, but it might be.

But, like any doctor who performs circumcisions will tell you, it's easier to snip the extra off than put extra on! I'd much rather start out too long than too short!

I've already got the 4:1 balun made for an OFC dipole, AKA 'Windom.'? Just need some copper wire and a bit of hardware to finish it up.

Ordered 21 December 2017.? GF gave me the money for it for Christmas.? (Gotta love a woman like that!)

Would love to know when the back orders start shipping.

Just finished building a Kits And Parts (kitsandparts.com) SWR bridge.? Says it's good for up to 100W intermittently.? Probably would accept the 10W from the uBitx w/o a problem.? Designed to output to a pair of current meters, it could be hooked up to analog inputs on the Raduino to read forward and reflected power.

I've bought most of mine at hamfests. eBay is also a good source, and McMaster Carr sells 2' x 3' sheet of double sided 1/16" for $48. That's 7x more than you need for this project, but if you continue making chassis for other projects, it may be viable.

Check out.

From the History:

I2C is a Philips patent and there was legal prroblem - so other companies started using name TWI. Generally it is identical protocol, but I've found information, that some functions (eg clock stretching) could be not supported in TWI.

But it does not matter in our case, and we cas use that names interchangebly.

Thanks again for providing the map, and thanks if you updated or put yourself on the map for the first time. I will use this map to visually show the distribution at least known thru this map of Ham Builders....practially all over the world. ?

I was going to do a new map for those entering the Hombrew Show and Tell and Contests, even and especially for those who are sending just images and the back story of their Builds. To further illustrate where this sharing was coming from. ?Well, I am not having much luck with that. ?Just not enough time for me to figure it out, I waited too late, actually didn't think of it fast enough....oh well....maybe next year....after all, what is the point of any of these efforts that are likely to grow Amateur Radio groups, especially clubs? Its to get more help? NO....but it can be a good side benefit....someone else will want to see the same thing happen....like look how many are on this site every day.....just amazing....and a lot of fun.....speaking of which....look what is on my bench



besides my BitX40 (my operating one) up on the shelf, down on the lower shelf are two locals from this talk group: W7RLF Ryan Flowers of miscdotgeek.com fame and fortune....and very recognizable is WB5YYM Randell Curtis own expandable BitX40.....I had a QSO with BitX40 months ago....how cool is that....from Arkansas to East TN....shooting off of a galvanized fence wire antenna Randell radios....because he has a whole station custom hand made by him.....a Forty 9er, an external Amp in a matching metal case also, and has been featured in a SolderSmoke blogpost......and he is a big Dr. Jack Purdum W8TEE Fan and follower of his projects. ?These radios will be at the Builders Fest, even though their owners won't....that is if they get out of my shack.....

You're completely correct and good point. Learned that the hard way a few times.
