Re: [Discuss-gnuradio] Flow with multiple sources, modulators and single

[Matteo Campanella]

I finally solved the problem, which was connected to the use of the NBFM modulator. Swapping it for an integrator followed by a VCO, everything works wonders. Here's the link to the working implementation of a multimode transmitter

Thanks for the link Ron, that’s indeed an interesting solution.

I’m still trying to understand why the matrix multiplier approach blocks though, and if there is a way to make it work, as it is so easy to implement a complete solution with multiple sources and multiple modulations and a single sink that you can switch at runtime ... maybe it blocks because of the different delays introduced by the filters on the two branches I’m trying to multiply?
