Sorry, I didn't mean to imply you needed the stream to tagged stream
block to make it work.
I just put in at the beginning so I could use the tag debug as a brute
force search to find out what was blocking the flow.
There are two sequential tag blocks - the correlate correlate access
code-tag from gnuradio and a block from gr-satellites - I would guess
that is all you need.
Select "pass thru" on the stream to tagged stream block - it should
still work.
