Re: [Radio Officers, &c] Re: [CW] Re: SOS de MGY - Titanic - Real? or Fake?
- Hello Peter,
Thanks for your comments (see below my SIG).
I've heard people send with a straight key at this speed. And it sound
more like a straight key at that speed than it does a bug. However to
support your comments, I only found one dash that wasn't timed
correctly - it was shorter than the others. I didn't hear any
variation in the dots, but neither did I hear variation in the other
I have one of Phil Boyle's excellent and accurate reproductions of the
Marconi Lever key (Guillotine key) used on Titanic - and I can send as
fast on that as I can on a 365. The 365 is smoother than the Lever
key and both have heavy spark duty contacts.
I do not have a program with which to measure the length of the code
elements except with great difficulty. It is easy with Adobe Audion,
but I cannot find my copy of the program, so I used the free Audacity
and the only easy way to measure a dot or dash is to trim the waveform
down to the dot/dash and measure the length of the whole file. Too
time consuming for me. But I did report on the inconsistant dash that
I did measure this way.
