[Discuss-gnuradio] Chunks_to_Symbols Symbol Table format?

Hi There,

I basically have two questions.
1. How do I specify the Symbol Table in the Chunks_to_Symbols block?
2.  How do I M-QAM (M = 8 / 16, etc) modulate data from the audio sink (speech)?

For the second part, I thought of the following setup:

Audio Source -> low pass filter + decimation -> float to char -> Unpacked to packed -> chunks to symbols -> root raised cosine filter -> USRP

Will this work for a very basic and simple setup?

Kind Regards,
