Sounds like the answer to me. Now I can just see myself trying to find those LORAN C pips amongst all the "grass" created on the APN-4 scope by the 56 spark plugs on the PBM!!

Yes. But LORAN-C can have more SLAVES per MASTER than LORAN-A. Also,
LORAN-A has several operating frequencies, LORAN-C only one.
The box is an LO and one or two BPFs. And possibly an AGC.
