<br>
I recently purchased a couple of DVB-sticks on Amazon, titled:<br>
<br>
"RTL-SDR, FM+DAB, DVB-T USB Stick Set with RTL2832U & R820T.
Great SDR for SDR#, HDSD"<br>
<br>
I got "No supported tuner found" when running the rtl_test
command. I see others have had the same issue, so when I finally
figured it out, I thought some of you might be interested. <br>
<br>
First of all, this stick has a FC0012 tuner despite the title.
Secondly this stick is obliviously wired differently than other
sticks with FC0012 because it needs different gpio settings. I
added a few lines to the rtlsdr_open() function in librtlsdr.c,
just before probing for FCxxx:<br>
<br>
/* initialise GPIOs */<br>
rtlsdr_set_gpio_output(dev, 0); <br>
rtlsdr_set_gpio_output(dev, 3);<br>
rtlsdr_set_gpio_output(dev, 4);<br>
rtlsdr_set_gpio_output(dev, 5);<br>
rtlsdr_set_gpio_output(dev, 6);<br>
<br>
rtlsdr_set_gpio_bit(dev, 3, 1);<br>
rtlsdr_set_gpio_bit(dev, 4, 0);<br>
rtlsdr_set_gpio_bit(dev, 6, 0);<br>
<br>
/* reset tuner before probing */<br>
rtlsdr_set_gpio_bit(dev, 5, 1);<br>
rtlsdr_set_gpio_bit(dev, 5, 0);<br>
<br>
With this modification the tuner comes a live and everything
works.<br>
<br>
Kindest regards,<br>
