This is exceptionally helpful Martin, so thank you! As it turns out, I have had zero time to work on the ubitx over the holidays so, I’ll be using this information for sure.
Again, many thanks!

Nice Work, Martin!

Martin, very interesting and successful concept!
Really fantastic work!
I use a similar “box” for backpacking:
Here is a better photo of the actual construction. The batteries I use are these:

Much cheaper iPhone 2G batteries like these
might also work, but I wanted to use a brand product with a complete datasheet. Also, the wires on iPhone battery replacements might be too thin for the ca. 1.5 A peak currents.

Today, the CNC-milled and color-printed front panel for the TinySOTA station arrived from Schaeffer AG. I can’t wait to put it into place

That looks terrific, you should have a big smile when it all goes in!

Nice work
Thanks for all your kind feedback!
Today, I managed to mount everything on the new front panel. The total station weight is now 329 g including the MTR-3B, TinySWR indicator, 2S 1000 mAh Lipo battery, DC-DC- boost converter for 9 and 12 V, Palm Pico Single, retractable earphones, volume control, and balanced charger that can be powered by a simple MicroUSB port; all in a watertight and extremely robust enclosure.
Attached, please find a few snapshots of the final result.

PS: The red and green LED are misplaced; will fix that asap.
Perfect hit, Martin!
That is an enviable radio!
Thanks for all of your nice feedback!
As promised, I will put instructions and files for 3D printing and front panel on a Github repository, but it will take a few weeks or so.

This is just AMAZING. I might have to do this with my MTR someday. Very nicely done!
Complimenti! Surely if you went with plastic screws you can get it down below 325g
German craftsmanship at it’s best

Hi,
the outer case are from Peli. The front panel and PCBs for the rest is designed by myself. The files are already on GitHub, see links above.

Thanks, github already in sight!!

I just saw that the link to the tiny USB charger for 2S lipos is broken, here is the new one:
