?I meant the rounded part to face in and the flat back to contact the leg angle stop. Thanks for the catch. I'll improve the directions.

Attached is a drawing of hole locations. I know what you mean about iterative measurement. I made a quick, 1 mm thick plate with holes to check these.

I have been looking at the schematics of the ubitx and sbitx units.
Both appear to use the IRF510, at least in the diagrams that I found. The sbitx is advertised as 20 watts and the ubitx is advertised as 10 watts. Are they using different versions of the same unit, or just a better design and heat sink?

What am I missing??

I definitely love Jeff's work and watch every video as they come out.? The only caution I would raise is that he tends to be working on the bleeding edge with Pi, so some of his older articles don't age too well, because once the stuff he is working with becomes mainstreamed usually easier ways to do things have been invented or discovered.? This is not the case for PCIe right now, it is still "bleeding edge" and his stuff is still the best reference IMO.? For USB I posted the Tom's Hardware link because I think it's easier for most people to follow.? In particular Imager can be used to do some things Jeff did manually.

I agree with Dave - should have noted that Jeff Geerling is an early adopter and he typically does not update his posts with information as features go mainstream. For example, I was following his guidance on setting up an NVMe drive using one of the PCIe adapters for the Raspberry Pi 5. Turns out it was missing one config change necessary to make it work with the production version of the board (but worked with the proto board he reviewed). That said, don't be afraid to use the Google or DuckDuckGo for any of the Pi-related questions posed in this forum. Get a consensus of advice and go with information that appears consistently across a number of YouTube videos and/or blog posts.

Bob,

That would be good if you have a chance.? Trying to place the holes once. I never seem to measure them exactly and find myself always printing, move a mm, print again, move a mm, repeat...

Just printed it, nice design!? I assume the rounded part of the legs face outside (away from the sBitx) ?

Sorry, I should have added the stock screen is the "official" Pi screen:

I would love to have a better display for the V2/V3, without so much wasted space around the edges.

LCD is for the sbitx v3.

That's all excellent news!? Sounds like you are having fun, and that many others are benefiting from your work.

One thing: is the standalone Telnet app now super-ceded?

I ask because I've updated our?sBITX HowTo's?page to point to this thread and list the programs:

• Telnet Companion App:?link
• sBITX Companion Apps:?link
  • sBITX Manager: An application that can be used to store frequencies and provide auxiliary control of the transceiver.
  • sBITX Scanner: An application that scans frequencies aiding in finding activity.
  • sBITX ScreenControl ~ An application to change the default window size for better scrolling such as using WSJT-X and fldigi natively on the the transceiver.
  • sBITX Backlight ~ An application to control the screen brightness for power conservation and eye comfort.

... and I don't know if the first line should be retained.

Hi Dave,

I will update the wiki since the applications have evolved. The AIO installer for "sBITX Companion Apps" will be the source for all future updates and additions. Links to the standalone apps will be posted there on the GH page to make it easier to find and learn about the apps.?

I have an original, LCD display available for a uBitx V6 if it needed.

Bob,

Perfect!? Do you have the dimensions on the location (x,y) of those screw holes? I will just make them an option on my 3d printed case and reference your work.

Hi Jeff,

Which radio needs the part?? A site, V6 uBiTx, or a V5 or earlier uBiTx?? There are three different screens, one for each plus the Nextion screen for the uBiTx mods.

Anyone know the model/part number for the LCD screen and driver board? Or where I can pick up another?

TY!

?? My case came with threaded inserts for M4 screws. Details like that are in the? printables link.

Nice job, Bob. What size were your screw holes on the case back? I checked mine some time ago, and I think they were M3. One didn't thread easily, though, and I didn't want to take the chance of stripping it out at the time. If they're all the same (which I assume they are), I'll open the case up, remove the board & re-tap it.

Thanks,
Mike

Today when I started sbitx I opened the LOG file and then closed it.
For the first QSO, it was written on the display only once and then it saved the QSO.
Maybe this is the solution?

Very neat Bob!

Here is a design for a folding tilt stand for portable operations. Tilts back 30 degrees, like my clip on design. When not in use the legs fold flat to the back of the sBITX case and the assembly does not extend beyond the heat sink, so size is not increased.
