jiangwy wyjiang at ljshuoda.comHi 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. Jiang Wenyi -------------- next part -------------- An HTML attachment was scrubbed...
