no ETI Stream with RTL2832U/R820T
When I try to create an "dump.eti" File is this empty.
$ ./dab2eti 227360000 > dump.eti Found 1 device(s): 0: Realtek, RTL2838UHIDIR, SN: 00000001
Using device 0: Generic RTL2832U OEM Found Rafael Micro R820T tuner Supported gain values (29): 0.0 0.9 1.4 2.7 3.7 7.7 8.7 12.5 14.4 15.7 16.6 19.7 20.7 22.9 25.4 28.0 29.7 32.8 33.8 36.4 37.2 38.6 40.2 42.1 43.4 43.9 44.5 48.0 49.6 [R82XX] PLL not locked! Tuned to 227360000 Hz. Tuner gain set to automatic. Waiting for sync... startup_delay=1 ^CSignal caught, exiting!
User cancel, exiting...
But the frequency is correct and DVB-T works. DAB Index for my Region 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.
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'
ok, but the issue won't get fixed here.
