Dear all
i have a usrp1, RFX2400 and WBX and i have a coaxial cable from the
wifi
card to the rfx2400 TX/RX port
i want to pass the stream from the wifi card to the rfx2400 then to the
wbx
to transmit it over the UHF band
how could i do that ??
here is the connection i have created (attached)
please help me as fast as you can
thanks

The WBX and RFX TX/RX antenna port is not full-duplex. Perhaps you want
a diplexer for your wifi card.
From the docs:
The user may set the receive antenna to be TX/RX or RX2. However, when
using an WBX board in full-duplex mode, the receive antenna will always
be set to RX2, regardless of the settings.

Also, in direct-cabled applications it is good practice to include
attenuation between the transmitting device and receiving device.
Many commercial wifi cards output 100mW (20dBm) which can damage a
WBX. We recommend limiting the WBX input power to -10dBm or less.

Quite apart from the other advice you’ve been given here about safe
cabling practices and antenna selections, it looks like you’re trying
to implement what’s a called a linear transponder. You’ve got your
sample_rate set to 32Khz, which is very, very, very much
narrower than standard WiFi signals. You’ll have to experiment with
the smallest bandwidth that sucessfully carries your
WiFi signals through.
