Re: [Discuss-gnuradio] turn off DC offset

[Julian Arnold]

Hey,

I've had a similar issue with a 3.7 version so maybe this helps.

For me, no other value than "True" (without "") would generate a call to 
"set_auto_dc_offset()" in the GRC generated python script ("top_block.py").

So, in order to disable DC offset tracking, a quick workaround would be 
to set "Enable DC Offset Corrections" to "True". This adds the desired 
call to "set_auto_dc_offset()" to your "top_block.py". Now you only need 
to manually change "True" to "False" in "top_block.py" and DC offset 
tracking should be disabled. Remember to not regenerate the flow-graph 
after making those changes as otherwise GRC will override your changes.

Alternatively, you can of course always simply add the line 
self.uhd_usrp_source_0.set_auto_dc_offset(False, 0)
to your script without using GRC.

Hope this helps.
Cheers,
Julian
