Thanks. Not sure I’m any the wiser. It’s not like Paul to be so obscure. So - the word “note” is embedded in “nanotechnology”...and that gives you “message received”. Hmmm.
Read the first bit "I've got your communication" as message received
now "memo" and "note" are embedded in the second bit
Memo and note = messages and are received in the wordplay
Jackdaw's answer to the parsing looks reasonable
