Using MTP to the SD Card I get under 0.8 M Bytes per second.

Using an €8 SD card USB reader I get 12 MB/sec or more copying from an HDD.

Turn off the tablet before removing or inserting a card, not just sleep.

Also for any device with an SD card don't copy content before using with calibre or it will take a long time. Create the folders (directories) you need and then connect to Calibre. Untick everywhere except folders that Calibre will use. Add rules for azw3, kfx, pdf, epub etc to appropriate directories and make sure default is memory card (will need changed back for devices not using a card),

Oh, rats! Copying 80,000 small files the transfer rate is only about 0.27 MB/s via MTP!. Now at 0.45 GByte of 26 GByte. Or estimation of 28 hours.

Should quit and dismount.

Edit
Now getting 30 MB/s via card removed and in cheap SD-USB adaptor. Now 4G done and 11 minutes left.,

That is always to be preferred. Better safe then sorry.

Now have MyWrite Nebo on it. Maybe 3rd in Productivity and €9.95, not a subscription

Far better than MS One Note, which is very clunky on Android though free, and has no offline handwriting conversion other than Gboard input to a text box.
Major differences from Nebo on Kobo (Advanced Notebooks on Sage or Elipsa)
  • Preview of handwriting as computer text as you write.
  • No temporary drop outs
  • Copy and paste works properly
  • Drag and resize is instant and easy
  • Conversion to text is much faster with double tap.
  • Conversion of sketched boxes & lines to chart works better and faster
  • Export and save as docx dramatically faster
  • Share export to other apps
  • Import PDF for markup/annotation (not tried it yet)
  • Add and change language without changing system language (on Kobo it follows main system choice)
  • Any colour. More flexible sketch insertions

There may be other better enhancements. There are Mac & Windows viewers and an iOS app. I know you can't import iPad Nebo file on Kobo. I will see can Android app use Kobo Nebo file later.

The advantage of Nebo on Kobo Elipsa and Sage is that it's free. It's hampered by eink and CPU performance. It's certainly better on Kobo than reMarkable's Notepad application.

No WiFi or server or cloud service needed (See Kindle Scribe).

I tried a wired headset on the tablet via a generic USB-A adaptor in a USB-C OTG adaptor. It works, but volume too low. So I bought €17 Primark / Pennys "surrounding" the ear earphone headset as I don't like the BT buds and not loud enough. Plenty of volume at 20% on tablet media volume via BT. The headset also has 3.5mm jack and USB-C charging (will charge from tablet). The + & - buttons work on Musicolet App, which works for mp3 audio books as you can set it to remember position on all files, or just files more than x.xx duration. It can play folders or playlists or you can make playlists on it. I have now entire CD library dating back to 1992 and some LPs, 78s, singles and cassettes on the micro-SD card. Keep meaning to digitise the rest of my 1960s 45s, 1970s to 1980s LPs and the 78s, some of which my parents had before marriage. Some 78s & LPs picked up S/H.
I have a customised player for 78s, Dual 505-2 for LPs & 45s and Sony TC 186SD for cassettes. Choice of Zoom handyrecorder or Creative external HiFi USB box for capture. Audacity on Linux to cleanup.

With some fiddling, a otg adapter,a hub and a USB stick I managed to get the NxtPaper 11 to recognise the Elipsa. Select use as portable storage. The file manager showed the two devices files in one window, but I was able to copy files. Eject only via Settinge -> storage.

TV and Radio

After a two week on/off search I found my old RTL USB-DVB-T TV stick.
I added the USB-C to USB-A OTG adaptor and a short USB-A extension cable.
The demo versions Android SDR Touch and Aerial TV worked, so I bought the €4.19 (inc 78c VAT) licence in App for the TV. The full version is an upgrade by clicking the lock icon on the running demo app, no doubt to ensure you have the required USB stick as otherwise the app won't load.

Ireland uses DVB-T for HD, so the old USB stick works also for HD and SD H.264. UK would need a newer one for DVB-T2. A DVB-T2 USB stick will work on DVB-T.
Some (nearly all old ones from UK) DVB-T setboxes and TVs will not do H.264 decoding (UK HD only, which was only ever on DVB-T2). Ireland has always used only H.264 for DVB-T, even for SD as well, so many TVs, before DVB-T2 was standard, sold as Digital TVs in Ireland only worked on analogue (till 2012 switch off), or as monitors with DVD, Consoles or set-boxes. We did a survey in 2012 and every UK owned retailer locally and most of the Irish ones (due to UK domination on wholesale back then before Brexit) had no Digital TVs that actually worked as such in Ireland, yet the €8 DVB-T USB sticks worked on a laptop to PC because the H.264 decoding was done on Windows/Linux/Mac.


The USA uses a totally incompatible system for off Air (ATSC), see map https://en.wikipedia.org/wiki/Digital_television so the common RTL USB sticks won't work. See map for your region Digital TV.
Regions where a DVB-T or DVB-T stick won't work
North America uses ATSC
South America and one part of Africa uses ISDB-T
Japan uses ISDB-T
China uses DTMB (Hong Kong may still use DVB-T)

Most do about 42MHz to 1.2GHz for SDR, but it's only 8 bit by bypassing the MPEG-2 TS decoder. So SDR and DTV use different Android drivers (free download).

Later when I get more Playstore credit I'll get full version of the SDR Touch app, which is about €8.99. It does various radio modes and needs an external upconverter for 50KHz to 50MHz (LW, MW/Broadcast and SW) which are available on Amazon, Ebay etc. It will do FM, AM, SSB etc on bandII, Air Band, 2m, 70cm, Marine etc. I've used it with free SW on Windows and Linux, including DAB and SSTV. DAB is now turned off here since the start of May 2021. Only RTE was prepared to use it and it had less than 50% coverage.

Better SDR based tuners are available. The dynamic range of 8 bits is terrible and really 12 bits is a minimum, but the SDR Touch app is worth while with a cheap DVB-T stick for casual FM-Radio, Marine (we have local coastguard weather), Airport (we are near Shannon) and Shanwick Air control as well as listening to Amateur radion on 2m and 70cm.

Some Android tablets and phones do not have the CPU and graphics performance needed. The Irish HDTV with optional subtitles was perfect on the TCL NxtPaper11.

Edit

According to reviews the SDR Touch key (€8.99 on Playstore inc Irish VAT) on Amazon can only be used on an Amazon Fire, not a regular Android device.

So far as I can tell, with macro adaptor and without tripod (lazy!), the TCL NxtPaper 11 uses a 3600 x 2000 mono panel with R G B stripes to 1200 x 2000, rather than a 2 x 2 cell on 2400 x 4000. It also seems to use sub-pixel addressing. However I'd need better photos to be sure. Despite having a similar overall resolution in dpi to the Kobo Elipsa, it looks a lot sharper; probably this is due to better grey scale (254 vs 14) and sub-pixel addressing. The eink panel cells also seem noisy, presumably because each cell is multiple black and white balls.

PDF page turns of a scanned magazine (UK format) are instant on the TCL and slow with a flash on the Kobo
