[Lowfer] " XR " HSCW experiment tonite on 186.100 KHz

[Andy - KU4XR]

Hi Charlie:

>From my google-ing tonite; it appears that the HSCW is accomplished
thru recording your transmission at a slower speed, then using
audio editing software to " Speed it up " to the desired " lpm ",
then the receiving operator records the transmit time frame, and 
uses editing software to " slow down " the speed to a decodable rate.
As far as transmitting is concerned now; keyers such as the K-12
will do HSCW up to 6000 lpm ( 1200 wpm ) that still leaves the
not so convienient need to record a time segment on the receiving end, 
and then edit it to decode any possible signal in the audio..

Curiousity has me wondering just how much information could be 
conveyed at the rate of 1200 wpm when a lowFER signal peaks above
the noise ??
A possibly interesting experiment ( to me anyway ) would be to 
transmit at 200 wpm ( 1000 lpm ) in a continuous stream, and receivers
monitor the frequency with ARGO, or Spec. Lab. and as soon as they
" SEE " a carrier trace; start the programs .wav recording. This
could be done each time a carrier trace appears. Then the audio files
could be opened, and slowed down by a factor of 4 to get to 50 wpm.
This could be decoded by MultiPSK as a .wav file...

Just something occupying my thoughts tonite... I'm always thinking
of something different to try.

Good to hear from you, 73 for now:
