Hello,

First thank you for this FL2000 hack, it's very nice!

I tried to make an FM & AM transmitter with it and GNU Radio. It's working fine if I save to a file and then use fl2k_file to transmit the data but with the tcp server and fl2k_tcp, my computer is not fast enough to sample in real time at 100 MHz. I also tried with a 35 Mhz sampling rate but it's not real time. Here is the diagram I used.

Is there a possibility to avoid sampling at a very fast rate if the data bandwidth is small to do the baseband to carrier shift?

Thank you,
Best regards,
Jean-Paul
