Alan,
Of course, the FCC rules on SS are outdated and ROS should be allowed
due to its narrow spreading range, but the road to success is not to
just rename a spread spectrum modem to something else and try to fool
the FCC. This is a sure way to lose the battle. The genie is already out
of
Just as an idea:
Ad a (non-random) idle to the soft ROS maybe with a bit higher audio level
selectable by the user
Can be used to resync, for afc, etc.
So decoding maybe a bit better
And you have overcome the SS problem (if it is a problem . but I do not see
any)

And, the response from the FCC doesn't provide any FCC position or
interpretation of ROS, and further says The Commission does not determine if
a particular mode truly represents spread spectrum as it is defined in the
rules.

Jose, my attempted help is to let you understand that the FCC believed
you when you said ROS is FHSS, so you will fail in any attempt to
reclassify ROS as just FKS144. The FCC will not believe you. What will
probably succeed is for you to continue to describe ROS as FHSS and let
the FCC permit

Does ROS have any flexibility like Olivia where you can change the Bandwidth? I
am thinking it must not. SS modes that we all have experience with ( Cells,

with each other (for the most part). I was wondering

I do not know of any way to change bandwidth in ROS. My observations

Could you show us a pic of Chip64 (your choice to compare it to ROS)?
Have a look at the links on my message 34845:
http://groups.yahoo.com/group/digitalradio/message/34845
The author of Chip64 uses DSSS but in a much narrow BW than ROS. How it works
is very nicely disclosed.
Warren,
Please allow me put my two cents. I would not expect so if the spreading
code is the same.
The adventage of CDMA is code orthogonality, each user has a different
chipping code that has little correlation with other user's codes., and
so, there is little mutual QRM.
As far as I
