Hi!
I'm modifying rtl_fm to change frequency and demod based on the date/time.
For the frequency i've no problem, but changing the modulation from wfm
to any other gives me no outout at all.
Which is the best approach to change the demod type in realtime?
(whitout shutting down rtl_fm of course!)
Many thanks!
Hi all !
Please excuse me if this is a bit off topic.
Is there any sense to tap the IQ signals from e4k or r820t to the
internal or external soundcards.
Is it possible at all (with r820t particularly) ?
(It could seem like reinventing funcube dongle, bet the
performance/price would be still right)
Best regards,
Zilvinas
I got a quite good (AM/SW)/FM/DAB/DVB-T USB dongle : Mirics FlexiTV
MSi3101.
http://www.mirics.comhttp://www.mirics.com/node/31
WFM , DAB/DAB+ DVB-T signals on air
well decoded by Mirics software ( FMDABplayer even on slow netBook,
while DVB-T needs fast PC) but Windows binary .
I noticed basic Linux software at address
http://cgit.osmocom.org/libmirisdr/
What the status of this software just now ( june 2013 )?
Thanks.

Yes! Tap. The only problem is a sound card can only accommodate 48K - 96K bandwidth, some maybe as wide as 192K. The noise at the center of tuning may wipe out much of this tuning. What is needed is a tunable "Zero IF" double-balanced converter like a SA602(612) or NC1496 on the output of the Tuner chip driven by a very clean VC oscillator, these chips have differential I/Q inputs so the tuner can be used as it was designed and not constrained by that funky 8-bit A to D chip. A 16 bit I/Q sound card conversion of the double-balanced IF tuner output would reveal much the slow 8 bit converter does not, like very good noise cancelation, ultra narrow-band RADAR signals, very high speed frequency hopping, and spread spectrum modulation.
I would create such a thing if I were not involved in more profitable ventures.

I want to use a rtl-dvb-stick connected to a fritz-box-dsl-router via tcp. Software running on
the fritzbox is freetz (www.freetz.org) and cpu-architecture is mips. So I created a makefile
and compiled the software without errors. But when I start the software (usb-dongle connected)
it throws a usb_claim_interface error -5. rtl_test recognizes the type of stick correctly but
throws identical error message. So I started rtl_test with strace - here you can find the
output:

Any tipps for solving the problem are welcome ;)

Hello,
i would like to work in ARM-Cpu environment with the
RTL2832 dongle therefor i need the Arm-WinCE .dll or Arm-Linux .o .
Where i can download the C, or C++ or Pascal source ?
Thanks for your help
Fritz
