r820tweak_patched installation

Post by Curt Carpenter » Mon Apr 30, 2018 4:19 pm

Hello!

I'm using Ubuntu 16.04 linux 32-bit and gqrx. I have been trying to use r820tweak_patch to access the 820T tuner registers, but get the following error messages:

/usr/local/bin/r820tweak:258: wxPyDeprecationWarning: Using deprecated class PySimpleApp.
app = wx.PySimpleApp()
Traceback (most recent call last):
File "/usr/local/bin/r820tweak", line 266, in <module>
main()
File "/usr/local/bin/r820tweak", line 260, in main
MyPanel(frame,-1)
File "/usr/local/bin/r820tweak", line 169, in __init__
value=self.device_list[0],
IndexError: list index out of range

Has anyone here successfully installed r820tweak_patch on Ubuntu?

Thanks for any info.

Hello,
for me worked:

sudo visudo
at the bottom of file you must add line
<yourusername> ALL=(ALL) NOPASSWD: ALL

now sudo no needed password

and small script for running gqrx with r820tweak driver and r820tweak gui

#!/bin/bash

sudo r820tweak /usr/local/sbin/gqrx/gqrx.AppImage &
sleep 5
sudo r820tweak &


gqrx must be run and then you can run r820tweak gui
