Hi,
I have a micro 2 ax5 and I need to enable the bias tee voltage on channel 2. I'm using GRC with the soapy custom sink. Any advice on what string and where to put the string?

Thanks in advance!

Hi Wayne,

Please try adding bladerf=0,biastee=1 in the GRC gr-osmosdr block. Alternatively, please take a look at gr-bladeRF, which has an option directly for enabling the bias tee.

Regards,
Rob

How to add "'biastee=rx” to gr-osmosdr source blocks if I install gr-osmodr with this way:

pybombs -p bladeRF install bladeRF gr-iqbal gr-osmosdr gqrx

?

"biastee=rx" can be added to the "device string" when double clicking the gr-osmosdr blocks.
