Re: wrong antenna mode

[jmfriedt]

Salut Maxime,
a lot of arguments seem to have changed with UHD4. In the
UHD: USRP Source, go to RF Options and for each board define
Ch i: Antenna
manually, replacing the TX/RX tab entry with your own. 
I use "A" setting.

Probably your Subdev Spec that might have been defined with UHD3
is no longer valid as well: in the General menu of UHD Source I had
to set
A:0 B:0
under Mb0: Subdev Spec.
Not sure how this setting relates to
https://files.ettus.com/manual/page_dboards.html
and the description that
Antenna Mode A: real signal from antenna RXA
Antenna Mode B: real signal from antenna RXB
for the BasicRX.

Best, JM
