when i run these two grc,i got a similar value of ser

i think that in the way of gmsk&fec,i will got a error rate value  smaller than the single gmsk,but i did not got it,

so i think there is somethin wrong in my grc,hope someone who can help me to check my grc ,or give me sone instruction about the using of fec.

thank you

Ekko,

Add a Tag debug block after your packet encoder and see if there are any tags coming out of it. I think packet encoder is not passing your tag. If that is the case, move your stream to tagged stream block after the packet encoder just before the FEC extended tagged encoder. Hope it helps.
