E4000 from Outernet and bias-tee


I would like know if your E4000 rtl sdr can be switch bias-tee off by software ?
What is the command line on linux and from windows ?

Thanks in advance.

Any idea ?

My wildest guess is no, the bias T cannot be switched in software.

Open it up and have a look. Possibly there are already some images out on the internet of the e4000.

Go to the Noo-elec site and see what they say about there E4000 RTL dongle.

The outernet E4000 has hardwired bias-t that can’t be switched, you will need to use a DC block inline or modify the dongle if you do not want the bias voltage.

Correct–the bias tee is hardwired.
