Hello, I am trying to find the best way to implement a bell 202 modem in gnuradio. The problem I am facing is that I need to produce two tones, one for mark and one for space, and I have to switch from one to other depending on which symbol I am sending. The duration of the tone (or tone switch) must be set exactly according to the baud rate of 1200 I have to produce.
I was thinking to use the nco class to generate the tones, and to output n samples per symbol at a certain fixed sample rate that would be enough for the 1200 baud, let´s say the standard audio 48000. Has anyone better suggestions to work this out?
