Re: 3D printed folding sBITX tilt legs

It would be best to have an adjustable tilt. I use the on-screen keyboard
all the time and it is very kludgy to type on it unless the incline is more
than 45 degrees.

Watch out for the length, you dont want to damage the internals or short the works with
a long screw. use the smallest length to do the job!

I can print one for you if you would like. The biggest expense might be shipping. I'm in NE Ohio.
BTW - big box hardware stores like Lowe's and Menards carry the screws. The 12mm M4 screws are

Re: ubitx audio amp problem discovered
Doc, in the linked vid at 11:10, it makes sense that the output impedance is about 5 Ohms. Then, after a jump edit, he multiplies it by 10 and uses 50 Ohms to solve for the output cap. Where did the

I don't have access to a 3d printer.? I would be willing to reimburse somebody to make me one of these folding supports.? I would like the person to include the screws - a local hardware supplier

Re: Sbitx vs ubitx power levels
Hi Roy,
Do you have a link that I can look at that you recommend for making one of those? What bands are you able to use it on without a tuner?

Thanks Bob!? I have been using any number of things to tilt my sBitx and should have thought of this.? I fired up a 3D printer after lunch and voila!? Fits like a glove and just what I needed.

I¡¯ve had good luck with a 40m EFHW and 49:1 transformer. It is about 26-ish feet long, don¡¯t revenge actual trimmed/tuned length.

Re: Sbitx vs ubitx power levels
Hi Evan,
I really do appreciate the advice and reasons that you have stated. Since I really like rtty/bpsk style modes as well as cw, I will most likely go for the sbitx model. Also, if modification

Re: Sbitx vs ubitx power levels
Hi Scotty,
I own six uBitx and two sbitx.? The uBitx, as delivered, can do SSB, and with a PC and sound card, it can do digital modes.? It is marginal for CW as it does not have a narrow audio

Yes, those are the dimensions I used for the back of the tilt mount. They are explicitly declared in the OpenSCAD source file.
As mentioned, I also checked the others in the drawing by printing a

Can you be a bit more specific? There is no i2s-nmap, but i2s-mmap.
