This seems to be the opposite behaviour of what I would expect. From the description above, I would guess that the source block has the antenna set to TX/RX. When you transmit, the receive antenna is forced to RX2. When not transmitting, the receive antenna is <user setting>. http://files.ettus.com/uhd_docs/manual/html/dboards.html#wbx-series You can confirm the behaviour with a test signal on RX2 and calling uhd_fft -A RX2. uhd_fft -A TX/RX should show only leakage -josh _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
