This is the key he used. He liberated it when the Navy discharged him in 1964.
This type of key is a “Navy Knob,” an American copy of a German Luftwaffe Key. It gets its nickname from the unique doorknob button. Several manufacturers made them for the Navy.
- CJB was J. H. Bunnell & Company
- CTE was Telephonics Corporation
- CMK was McElroy Electronics
- CMI was Moulder Insulator
Dad’s key was a Moulder, and it was one of two keys in his amateur radio station (the other was a Vibroplex Deluxe Original). I remember the melody as he sent code between 20-30 words per minute.
Dad communicated with people all over the world using these keys, either aboard NKQT or as W4WYO.
Recently, I started using the Moulder as part of my “Scout Portable” radio station.
It’s a solid key; very easy to use if you have good technique.
If not, here is a Navy Training Film on how to properly send code by hand.
