Hi Marcus,

I'm not following this thread closely, so maybe I missed something that
has already been said.

In gr-satellites I'm using the "Correlate access code - Tag"
extensively, so if this has been deprecated I would like to replace it
by something suitable.

I'm currently using GNU Radio 3.7.13.4 and the block "Correlate access
code" appears as deprecated, but "Correlated access code - Tag" doesn't
appear as deprecated.

If "Correlate access code - Tag" is deprecated or is going to be
deprecated in GNU Radio 3.8 (which I haven't tested yet), what could be
suitable replacements for this block?

Maybe it could be good to make the effort to use the "Header/Payload
Demux" block, which at first glance seems too complicated for the use
I'm doing? In gr-satellites my main use for "Correlate access code -
Tag" is to detect a syncword and add a tag, so then I can use one of my
custom blocks to create a PDU of a fixed size where the tag starts.

Best regards,

Dani.
