[CW] McElroy Bug Serial Numbers List

[D.J.J. Ring, Jr.]

No ship master click on merchant cargo ships.  Chonometer, clock log with
daily entries of how slow or fast Chonometer was compared to radio time
ticks from WWV, WWVH, CHU. MGY, YV? In Venezuela, VPS Hong Kong (only Morse
at 1200 local sent on 500 kHz), JJY Japan, Russia, China, etc. and a
sextant taking angle of North Star at the last moments of maritime twilight
where you can see both stars and horizon gives you latitude, longitude is
given by observing noon sun, obtaining time and consulting the tables.
That was the 2nd mate's job, I got the time tick!
