Ref. Earhart sending CW with a mike button;  When I started as a cop in
the KC area some cars still used the old Motorola 30-D "twin coffin"
radios with a dynamotor.  To get a message out you had to "press, wait,
then talk" because they simply wouldn't transmit until the dynamotor
revved-up.  The first word or two would be lost if you didn't wait.  It
was a practice to "click" or double-click the mike button as a greeting
to a buddy, or as an informal comment or acknowledgement of some air
traffic.  You simply couldn't do the "clicks" if you were stuck with a
dynamotor unit.  I don't see how one could send CW with the mike button
unless it was SUPER, SUPER slow, maybe 1 or 2 WPM?   Doug Seneker, n0wan

Hi,

The following is an e-mail I received from Alan.  I don't have an answer
for 
him, but I thought if I'd post his question here, we could get an answer
from 
one of you.  If you have this information, would you please let him (and
carbon 
me) know?

Thanks!

We are having a lively discussion about what is produced when a mile
button is 
used to send Morse Code. The radio in question was in Amelia Earhart's
Lockheed 
Electra 10E on July 2, 1937. She supposedly had left the key behind so
had to 
use the mike button. The radio is believed to be a Western Electric RA-1
HF. 
More information may be found on the TIGHAR.com web site but I think I
have it 
all correct.

The specific question is in regard to the dynamotor churning up each
time the 
mike button is depressed or if it does. The actual concern is whether
fairly 
clean dots and dashes could be sent or whether the nature of the radio
would 
have it difficult to send readable code. would some beginning characters
be 
lost? Would some dots and dashes be difficult to discern?
