For iOS users looking for a portable FT8 solution, you might want to give this a try. It can call CQ on its own and automatically run the sequence when someone replies—set it and forget it.
It adds about 3 oz to your pack(reduces $30 from your pocket) and frees up your iPhone for more important tasks. More details:

You let (your) cat out of the bag!
I’d never heard of a Cardputer before but I ordered one last week and successfully (I think) burned your firmware at the weekend. I’m yet to try an activation but the Cardputer ADV and QMX seem to be working.
Hope to give it a try soon.
Thanks, 73

I too had never heard of Cardputer before, but have just ordered one to try this out!
I thought it was a ZX Spectrum at first sight.
Hi all 
An other one without TRX
I think 0.4w or 3w out, all in one (working & logging SOTA / POTA etc.)
Enjoy your ZX81

Thanks for trying it, and thanks for your attention. I googled the ZX Spectrum and learned a bit of its glorious history — good stuff.
I’ve brought DX-FT8 on a few SOTA trips (including Mt. Whitney), and it worked well. I only ran into two issues:
It’s a little bulky (I admit I’m being picky). Not a big deal for a day trip, but on multi-day trips it makes me think twice.
It puts out about 0.5–0.7 W, which is sufficient and fun to play with — but when time is limited, 2–3 W makes it a lot easier to get the job done.
Mini-FT8 is entirely inspired by DX-FT8 (and I made a small contribution to improve its UI). I haven’t brought it to a summit yet, but in a few POTA field runs it worked seamlessly with the QMX, and I was able to log about 10 QSOs in roughly 45 minutes. Mini-FT8 is optimized specifically for QRP portable operation. Also, the device is commercially available and very affordable.
I hope it helps make FT8 more popular among SOTA activators.

Another point: since Mini-FT8 supports free text natively, it could also be used to beacon your location in a distressed situation—useful if a SOTA operator doesn’t have (or forgot) an InReach. It’s not a substitute for dedicated emergency gear, but it can add a little extra safety margin, just in case.
The light-weight benefits of the Cardputer would likely be offset by the binocular microscopic I’d need to carry to be able to use it 
There are lightweight magnifier options, too.
I’m totally aware of its limitations. If you set everything up at home first, then in the field you only need to do three things:
set the time
connect to the QMX
enable the beacon.
And you can do all of that from the keyboard without really needing to look at the screen.
Hi Wei @AG6AQ
Can you make an AZERTY keyboard, it will be interesting for some EU countries, including France 
I am currently spreading the word in my region.

Hi Éric,
The project is open source, and the UI interface was entirely generated by ChatGPT (Codex) based on my instructions, so keyboard re-mapping should be straightforward. If you can compile the code and provide the re-mapping table to ChatGPT, it can update the code for you. I probably won’t do it myself, but I’m happy to answer questions.

Merci Wei
The reason I asked the question is that I know nothing about programming. 
Please join https://groups.io/g/qrp-portable for announcements, updates and discussion if you’re interested.
I will let this thread sink.
