Hi All
I bought a cheap DVB-T stick that was supposed to be a RTL2832U with a
FC0012 tuner with RTL-SDR support. As might have been expected given the
price, it doesn't work. The various rtl_ tools all report "No supported
tuner found", eg rtl_eeprom gives:
> Found 1 device(s):
> 0: Generic RTL2832U OEM
>
> Using device 0: Generic RTL2832U OEM
> No supported tuner found
> Enabled direct sampling mode, input 1

The vendor did give me a full refund suspiciously quickly, so clearly the
lack of advertised RTL-SDR compatibility is well known to them!
I then took the cover off, and it does have a chip that's labelled
RTL2832U, plus another similar sized one I can't read the label of.
After a bit of searching, I found this old post with a patch to list all
the I2C devices:
https://www.mail-archive.com/osmocom-sdr@lists.osmocom.org/msg00454.html
That reports:
> I2C devices found:
> 20 a0 a2
So there is something working there, but I'm not sure if it's enough...
Is there any hope for this stick? And if so, what would my next steps be?
Thanks

Hello,
Is there any chance the following patch could be reviewed and/or merged
into upstream gr-osmosdr? It allow multiple Airspy devices to be used
(which is sadly not possible without the patch). The patch is already used
in the downstream gr-osmosdr package in Fedora for last two years and seems
to work without issues.

Thanks!

Hello,
Please, consider doing a new tag/release of rtl-sdr. The last tagged
version is from 2018 and there were many changes since then including the
recently added RTL-SDR V4 dongle support.
Thanks!

After seeing the osmo-fl2k[1] project, I've bought a USB VGA dongle,
hoping it would contain a FL2000.
The model I've bought looks identical (from the outside) to the black
one on the picture. Unfortunately it contains a different chip: a
Macrosilicon MS9120.
There is not a lot of information about this chip, the manufacturer does
not even publish a datasheet (I've sent them an email to ask for one,
but don't have high hopes).
What I've found so far is:
- someone's reverse-engineering attempt of the android driver[2]
- a bit of python code to read & write the chip's memory[3]
The second thing is for a different chip by the same manufacturer, but
it seems to work with my device as well.
So, I was wondering if anyone here has already attempted to re-purpose
this chip as a transmitter :)
cheers,
