<div>Hi Marcus,</div>
<div> </div>
<div>librtlsdr is OK, because rtl_tcp works fine, which transfers full I/Q spectrum of ~ 1.4 MHz to SDR# on Windows/PC.</div>
<div>The problem must lie in rtl_fm. By the way, the I/Q demodulation "raw" mode is erroneous, too, when having compiled on Raspberry Pi 2.</div>
<div>Something else i could try: use the binary compiled on Raspi 1 B+ on the Raspi 2. I'll check this, this evening.</div>
<div> </div>
<div>Before going for painful debugging, it would be fine if someone else could reproduce the problem .. or say that it works fine.</div>
<div> </div>
<div>kind regards,</div>
<div>Hayati</div>

<div name="quoted-content">Hi Hayati,<br/>
<br/>
I'm totally not used to development on Raspbian, but:<br/>
It's really strange that running the same software on the same distro<br/>
with the same RF device would give different results.<br/>
<br/>
So, debugging is on :/ I'd say you should use rtl_sdr to get raw IQ<br/>
samples, and then have a look at them on your PC. If they are ok, one<br/>
would have to look a bit deeper into rtl_fm, if not, something goes<br/>
wrong on the librtlsdr side of things.<br/>
<br/>
Best regards,<br/>
