Switch ON/OFF the DC power to the Antenna (HackRF)

[Mihai Oprea]

Hello,

I know that Hackrf has this feature implemented in hardware, to be able to supply your preamplifier over the coax. cable, so I think it would be very useful for GQRX to have something like a button for enabling that.

Thank you!

Because GQRX uses gr-osmosdr for connecting devices, you can add "bias=1" to the device string. "hackrf=0, bias=1"

Excellent!
This is very helpful. At first, it didn't worked due to the space character after the comma :)

Thanks!
Bye.
