You will always receive your own transmissions. You really *DO NOT* want to disable antenna switching, since this is what protects the RX chain from being connected to the same port you're transmitting from, and incurring damage.Another problem I have is that I'd like to do a mixed mode repeater (from digital to analog and viceversa). My radio (USRP B200) is full duplex so I should be able to do that. However, I can't figure out how to do that in a single flowgraph (TX and RX). If I set the source parameters to use the TX/RX antenna, any time I switch from RX to TX, the sink moves automatically to port RX2 which means I'm receiving my own transmission. I'd like to be able to disable the automatic switch of antenna without stopping the RX flowgraph. Is that possible? Appreciate any help. Adrian
The TX-to-RX isolation isn't that "deep", so you'll nearly always receive your own transmissions, and you have to structure your signal flows to deal with that.
