Hi all,

Can anyone confirm if the RTL dongle bias tee can be used in gqrx when streaming data via rtl_tcp? I have tried adding bias=1 to the device options but it doesn't seem to make any difference. This option does seem to work when you plug the dongle directly into the computer.

Thanks,
Randall

bias=1 in the device string is only for rtlsdr device connected
directly o the computer. If you use rtl-tcp you have to enable bias-t
when launching rtl-tcp using the -T option.
