I am trying to replace the QAM mod/demod blocks with constellation
mod/recvr blocks in my flowgraph.
With QAM mod/demod, the first few and last few bytes of the output file are
junk.
With const. mod/recvr, 100% of the output file is junk. What could I be
doing wrong??

The "selector" module in GRC is listed as "deprecated". Is there a
replacement for it?
I am trying to just get a way for the GUI dropdown box to allow me to
select different constellation objects (BPSK, QPSK, QAM16) for the input to
my graph. The selector works fine for this, but I'm assuming it

Hello, I recently tried running volk_profile because I was getting signal
discontinuities when using the gmsk mod block with a samples per symbol
value greater than 8.
I ran volk_profile and it generated a volk_config in my home directory. Now
when I run my flowgraph (file source to gmsk mod to

We couldn't capture anything when we put wireshark connector after 'decode

Hey Kacie,
I don't have time to try you example right now but one thing to watch
out for is unpacked to packed conversion.
I think the Constellation Modulator expects packed bytes at the input.
However, you are sending unpacked bytes from you vector source.
Look at [1] for a block that can help
