Hello everyone, I'm new to SDR and trying to implement transmission with AM Modulation using uhd library with B205mini board.
Currently I have following procedure: Set RX and TX parameters for RF frequency, channel 0 Set sampling frequency to 1M samples per second Set RX and TX gain Receiving as sc8, sc8 Transmitting as fc32, sc8 -loop: Receiving: As usual with AM demodulation and it is working Transmitting: On audio sink get next 4096 samples of 44.1KHz 16 bit PCM raw audio Convert each 16 bit sample to complex float with Q=[audio sample normalized to -1 - 1] and I = 0 Resample (simple interpolation) 44100Hz buffer to 1MHz Send buffer for transmission -end loop As RX and TX have same frequency I can see data on RF Analyzer, but it didn't demodulates to an audio signal. Am I missing something or my assumption is wrong on some steps? Regards, Ernest
