Anyway... I am really out of time and I got upset with this loop. Here is my plan and I want your advice... eventually I am not gonna use the NCO... because my RF Front-End is RTL-SDR Dongle which has its own tuner (VCO). Eventually I am going to calculate error in FPGA then convert it to something that RTL-SDR understands and feed it to shift the phase according to error... I think it has some register to control phase. As my main problem is controlling the NCO because it doesn't have a separate phase input, this is going to make my life much much easier. So, how about stop working on that and begin implementing using the RTL Dongle?
