I'm curious about the high incidence of the number "3" in Betty's report - in order, the "3-phrases" are:
58 338
South 391065 Z or E
fig 8 - 3. 30 500 Z
3E MJ3B
Z 38 Z 13 8983638
S309 165E {in brackets}
3.15
3Q rd 36
J 3
3630
38-3
3
30
Amelia's transmit frequency of 3105 of course comes to mind. In addition to the 22 instances of "3" itself, there are 8 instances of "8," and 4 instances of "38." I realize that the "S309 165E" has been proposed as a position; perhaps the other "3" instances are fragments of this position, repeated (and transcribed only partially)?
