Currently trying to transmit a BPSK and a 4-FSK(MFSK) signal via GRC using USRP, I have two attempts at it but don't seem to be going anywhere. Still fairly new to GRC. For the BPSK, how will this signal appear on the spectrum analyzer? I have seen general images of the signal shape online but pretty sure what I see is not it. Will I be able to hear the BPSK signal, if so what will it sound like?BPSK Flowgraph
As for the 4-FSK, I seem to have something but the spikes I generate are at different amplitudes in comparison with a FSK signal I had generated a while ago that had the spikes at the same/similar amplitudes.
I can share my flowgraphs if it helps. Also it would be great if anyone had known working flowgraphs for these concepts to share for comparison or even be able to edit some features of mine. As for the details I care about, I really need to be able to specify the excursion/deviation between the spikes.
