Hello gnu-radio friends.
I would like to realize RFX2400 full duplex configuration.
I am using RFX2400 on USRP2 and tried to transmit and receive(fft.py at
But I got unstable spectrum for both TX/RX.
Here is the video
And configuration is as below.
2-+RFX2400( RX2 )±—Signal Source.
I found RFX2400 schematics from below URL
And I believe this situation is because of U202 / U209 to swith state
A->B and B->A in very often.
I would like to use both U202 / U209 to fix the swith state always to
Would you please let me know how to make U202(RFswitch) / U209(RFswitch)
to A state.
(say “full-duplex mode”)
Do I still need to hardwire fix the RF-swith to A? if there is no FPGA
/ firmware available to fix them.
Thank you very much in advance.
