Hi all,
I have a RFX2400 daughter board, which is full duplex.
When testing tunnel.py, I found backoff happened when TX/RX was tramitting
because RX2 is sensing.
I am wondering is there any way to disable RX2 to make RX2400 work in
half-duplex mode?
Thanks
Li

RFX (also SBX and WBX) can be used in a half duplex configuration by
setting the receive antenna to be the TX/RX antenna port.
For example:
usrp->set_rx_antenna("TX/RX");

Hi Ethem.
thank you very much. The AGC system object and its documentation were
extremely helpful. thanks!

Hi,
I'm looking for used USRP2, N200, N210 and daughter cards for my project. I
need more than one, but multiple systems. Please email me at
[email protected].?
Thanks for looking !!
