And the mis-information continues: I did not state that Spread Spectrum
does comprise a means of encrypting.

Alan,
Thanks for taking the time for a comprehensive reply! Remembering what
happens during a contest with overcrowding made me wonder. The problem
is that, with stations operating all independently, it is difficult to
determine when throughput drops to the point it is not worth the effort.
Now lets cut to the chase:
THE USE OF SPREADSPECTRUM, THAT IS, THE USE OF BANDWIDTH EXPANSION
TECHNIQUES BY ADDING PSEUDORANDOM DATA, NOT CREATED FROM THE USER INPUT
INFORMATION DATA, IS OF NO ADVANTAGE IN IMPROVING THE END TO END PERFORMANCE
OF A LINK, WHEN COMPARED WITH PROPERLY SELECTED
Lester,
Months of testing of all available modes on a 200 mile, weak signal,
path on 432 MHz support what you say. Contestia (or Olivia, but slower)
has surfaced as the most reliable mode we have found in the difficult
environment of signals marginally above the noise, fading (QSB) as deep

I think if 3 kHz SSB is ok, that 2.25 kHz modes (ROS as an example) should be

I agree, if people had more flexibility as to where to operate it

Here we disagree somewhat. I would mostly agree for areas like 40m,

Hi.
Listening on 30 meter tonight, I noticed signals as in here:

see at 10.120 KHz and between 10.110 and 10.114 KHz
These type of signals are also often
Wasn't that part of the infamous fake FCC response that Jose posted on his

ROS is not Spread Spectrum because the 3khz HF standard channel is

For what reason (technical advantage) would you advocate the use of SS at
HF. (My apologies, if I am off base, for assuming that you would advocate the
use of SS, by the “lost cause” descriptor) .

Hello friends,
I don't know about you , but I feel it is time to leave Jose and his ROS
mode now.
He doesn't deserve that much attention.

Julian,
The other side of the coin is that we must share frequencies (because
there is limited space), so in order to do that, it is necessary to be
able to understand a request to QSY or a QRL. When there was only CW and
phone, this was always possible, but with digital modes, if you do not

Tnx Sigi,
Are those amateur transmissions?
Look to me as occupying quite a few channels and that is
done on 30m ?

I agree. Which is why people using ROS with a program that supported no other
mode (nor RSID) caused such a conflict with people running other software that
supported anything but ROS.

What are you basing that statement on??The Hamspots page? You need to take
a look at the left column - see the red squares? That indicates that the spot
was auto-generated by the ROS software -- BOGUS spots! The real spots are
the ones w/o the red square - I didn't see more than a

Jeff, I am monitoring it Few amateurs are, I believe.
Few amateurs ever tried it. I used it before the illegal

( My opinion )
You have to listen abroad to hear/see the activity.
I would say in spite of the actions by rhe author.
Users seem to like it.
I like it.

Your Subject says ROS is better. Where can I read about the changes and
improvements? Can users control whether ROS should generate the artificial
spots?
