Super demo of MCW...! Fans of airport non-directional beacons (NDBs) will certainly appreciate. Also Amelia Earhart's primary aircraft receiver - a Western Electric 20B with model 27A remote control "head" - didn't have a BFO but she could have listened to Navy and other MCW code signals.
I've been a ham for 30+ years, and only learned of MCW by your excellent explanation...many thanks!
