[PATCH] lib/xtrx: honouring/using the loglevel parameter
by Gwenhael Goavec-Merou 20 Mar '24

20 Mar '24

loglevel parameter is never used and let loglevel to DEBUG, with an annoying flood of message in terminal. This patch adds a call to xtrx_log_setlevel() at xtrx constructor level.

Cheap RTL2832U / FC0012 gives "No supported tuner found", but has I2C devices
by Nick Burch 05 Dec '23

05 Dec '23

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 > > Current configuration: > __________________________________________ > Vendor ID: 0x0bda > Product ID: 0x2838 > Manufacturer: Realtek > Product: RTL2838UHIDIR > Serial number: 00000001 > Serial number enabled: yes > IR endpoint enabled: yes > Remote wakeup enabled: no > __________________________________________ 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 Nick

gr-osmosdr: Multiple Airspy devices
by AsciiWolf 03 Nov '23

03 Nov '23

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. https://osmocom.org/issues/5144#note-4 Thanks! Regards, Daniel

MS9120 USB VGA dongle
by Niklas Cathor 02 Nov '23

02 Nov '23

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, - niklas [1] https://osmocom.org/projects/osmo-fl2k/wiki [2] https://github.com/animaone/macrosilicon_reverse_engineering_journey/ [3] https://github.com/hwti/ms210x-tools
