+This block is a basic message source for testing purposes.
+
+It takes a list of strings as input, where each string
+is a whitespace-separated list of hexadecimal values representing the data bytes of a message including the gsmtap header.
+
+Such strings can be obtained using the message printer with option "Print GSMTap header"
