i want to ask if there is a convolutionnel encoder in GRC wich can
achieve a coding rate = 2/3 or  3/4

No, there is nothing pre-built. Encoders are fairly easy to write as
a custom C++ block, however, so you have that option.

gr-trellis contains a trellis encoder which I’m pretty sure can do
what you want. See the docs in gr-trellis/doc
