Hi Alexander Chemeris,

 

According to rx_multi_samples , I write a program to receive samples from two channels on the same board.

The program receive samples from 2 channels and calculate the signal strength respectively. The signal is from a BTS arround.

I find the difference of signal strength is very big, about 20dB, and channel 1 is bigger than channel 0.

I  exchange the antenna and feeder of the them, but the result is same.

I think there is some problem, but I cann't find it.

Would you please give me some sugguestion?

 

Best Regards.
