Re: [Discuss-gnuradio] Dx Patrol Setup

Some applications (e.g. DVB) automatically acquire the RTL at

boot, preventing Gnuradio from opening it.

sudo rmmod dvb_usb_rtl28xxu rtl2832

at the command line, each each boot, or

blacklist the device by creating a somefilename.conf file in /etc/modprobe.d

(may depend on Linux distribution) containing:

  blacklist dvb_usb_rtl28xxu
  blacklist rtl2832
  blacklist rtl2830

I have been buying today a DX Patrol SDR board. Works on Android,
however I'm getting some troubles with GRC.

A Terratec board with an Elonic s E400 tuner is working without any
major problem at the test frequency (98.6 M).

May I ask for help?

Tnx
