IIRC = "if I remember correctly". The documentation issue stemmed from someone who complained that PACTOR, and maybe other digital modes, could be considered "codes or cyphers", and the FCC ruled that they weren't because they were publicly documented. The source code has not been released by SCS, however. A public spec would resolve the issue of whether ROS is SS or not.
I can't locate a reference to this issue, but if no one else remembers it, I will do a more intensive search on the subject I'm still wondering how CHIP-64 seems to be allowed on HF by the FCC. It is admittedly Spread Spectrum. -- Dave - AF6AS -------------------------------------------------- From: <[email protected]> Sent: Wednesday, June 02, 2010 1:01 PM To: <[email protected]> Subject: Re: [digitalradio] ROS MODEM OFFICIAL GROUP > Hello Dave, AF6AS, > > "IIRC" what does it stand for? > > There has to be enough information to at least reverse-engineer a mode by > the FCC (and the NSA). > > Is that documented somewhere, not that I want to question the statement or > you..... > > What about something like: "Those need to be able to read/decode it under > all circumstances " > > 73 Rein W6SZ > > > -----Original Message----- >>From: Dave Sparks <[email protected]> >>Sent: Jun 2, 2010 2:14 PM >>To: [email protected] >>Subject: Re: [digitalradio] ROS MODEM OFFICIAL GROUP >> >>Oops, I missed that. >> >>What I *THOUGHT* you were saying is that you tried making a call (to a >>station with the current release) and succeeded.
