Ideally, I would like to see the entire packet (including the preamble
and sync word) to start to work my way to the format of the packets from
there. I am using the power squelch with the gate to limit the captures
to just when a signal is over a certain strength. In a perfect world, I
would like to have "Binary Slicer" -> "File Sink" where the file
contents are the binary stream (10101010101010 not to be confused for a
binary file) or hex output (0xAA 0xAA). I could probably tag the
preamble in with the Correlate Access Code?

Jay,
Thanks for the inquiry. Is there a specific protocol or format you
are trying to work with? Are the frame size fixed in length or
variable? The answers to these questions will dictate whether you
can use an existing block or if you will need to write your own.
Writing a block to parse things after the correlate access code
block is relatively straight-forward. If you are using the (tag)
version of that block, you simply need to look for the presence of
that tag to delineate the start of a frame.

I have a question about handling data after binary slicing in
the demodulation portion of handling a signal. Currently I am
taking that data and pushing it through the Correlate Access
Code block then into a file sink. This produces a data file. I
didn't know if someone could tell me a block or method that will
output the binary stream (or hex stream) to a file or stdout for
real-time view of the pack contents. Currently I have some
python code that converts that data file into binary/hex which
is not idea.
Thanks,
Jay
