Hello, Martin 1. Would you please tell me where the "manual page" is? Because I cannot understand *How the Vector source works* (tagged_streams.make_lengthtags((packet_len,),(0,).length_tag_name)? and *where the "Import"block grab the value from* (from gnuradio.digital.utils import tagged_streams), (import numpy), and (import random)? I just need to know how *vector source *related to those *import *block
2. And you are saying keep "*vector source*" block not replace with "*file source*" block. How can *vector source* import and read my *.dat? Thanks again.
