no ETI Stream with RTL2832U/R820T

[schmidicom]

When I try to create an "dump.eti" File is this empty.

$ ./dab2eti 227360000 > dump.eti

But the frequency is correct and DVB-T works.

I have tested it with and without the driver "dvb_usb_rtl28xxu", but the result is the same.

The file is empty, because the stick did not yet finish to tune to the desired frequency - otherwise you would get a list of the broadcasted programmes.
As your stick does NOT have an E4000 tuner, the autogain feature does not work and you have to specify a gain value by hand (via try and error).

I have tried all 29 Gain-Settings and now the DVB-T does not work anymore. Probably the device is defective.
The following device takes the the auto gain feature work, right?
NooElec NESDR XTR+ Tiny Extended-Range TCXO-Based SDR & DVB-T USB Stick (RTL2832U + E4000) w/ Antenna and Remote Control

IIRC libsdr and the DVB-T kernel module can't be active at the same time, so you have to disable libsdr. I don't think the hardware is broken; hardware never breaks :-)
$50 is way too much for such a stick...on eBay there are some sticks which (claim to) have an E4000 tuner...this should be much cheaper.

Hi,

same problem here in Madrid on FU-E (channel 11B) muxer.

Stick is the Noxon DAB stick, works with latest sdr-j-dab (i have installed a .rules file to disable the Linux kernel module from loading on this stick)

Viterbi, etc. enabled.

Problem was solved with a patch that has been integrated. My location is somehow challenging and I needed to control the gain.

I have the same issue. RTL2832U/R820T.
Original driver blacklisted, tried all gain settings , device works fine(tested with gqrx on another system) Is it possible to get this dongle to work, as you claim to support this RTL chip???

@steeley Please try the code at https://github.com/Opendigitalradio/dabtools and resubmit the issue if it's still a problem.

[steeley]

Gave it a try but still no good...
This time at gain 28.0 it did say locked and printed 13 sub child lines, then went ' lock lost, resetting ring buffer'
Tried playing one of the sub streams and it did nothing and then went 'signal caught, exiting'

[kylegordon]

ok, but the issue won't get fixed here.
