[USRP-users] No signal on TX/RX port

Hello,

I have 2 USRP1 each equiped with a RFX900 daughter board.
I have put antennas on each port of those cards (both RX2 and TX/RX).

When I transmit from one USRP using the TX/RX port, I can only receive on
the other USRP using the RX2 port, I don't see any signal on the TX/RX port.

Simply put, here what happens :
USRP #1 TX/RX -> USRP #2 RX2 == OK

USRP #1 TX/RX -> USRP #2 TX/RX == Not OK

The same happens the other way around (from USRP #2 to USRP #1)

I have attached the simple flow graphs I used for testing purposes as well
as the results I obtained.

Is this a normal behaviour or am I doing something wrong?

Thanks for the help,
Seddar Jawad
