Hi,

I build a TDD system with X310 and ubx160 v2, which uses TX/RX for both TX and 
RX. However I found the TX output power is extremely weak. Then I tried to 
assign RX2 as receiver anteena and I get approximately 20dB stronger TX signal 
with almost same code. The main difference is: for two anteena case, in each 
subframe TX send one burst, while in one anteena case, TX just sends zeros 
instead of stoping transmission. The installed uhd version is 3.9.7.


Does anybody know what could possibly be reason for this? And how could I 
achieve full power with single anteena TDD system?


Thank you!
