Hi there. I have a usrp device, namely B210 and i would like to know if it is possible to make a dual transceiver. The think is that i want to receive two different frequencies and transmit them on other two frequencies. In other words, i would like to make a repeater of two frequencies. I manage

Hi Marcus, Yes, I added a resampler to upsample by 250kHz and scaled the IQ samples by dividing it with 2**16, since each IQ is of 16bit. With this it started to work. Now, I want to keep changing the IQ file at run time. I have a lot of IQ files in current folder, which I want to use for trans
