Delighted I am to find the 1998 version of 47CFR97.311 on the GPO website, attached. We are both maybe correct.
The FCC prescribed the method, the operator filled in the variables, which he kept in a log and logged it every time s/he changed a variable. ----- Original Message ----- From: "Alan Barrow" <ml9...@pinztrek.com> To: digitalradio@yahoogroups.com Sent: Tuesday, July 13, 2010 3:03:01 PM GMT -06:00 US/Canada Central Subject: Re: [digitalradio] SS and the FCC definitions bg...@comcast.net wrote: > I'm thinking another reason for the restrictions - SS is also a very > good means of encryption. > The previous rules on SS required use of a particular type of SS and > the key number was specified in the rule.. > Probably in a pre 1999 ARRL rule book , if anyone really needed to > look.

I know from first hand experience that all you have to do is be prepared to present any coding sequence upon demand. And that coding (viterbi, pseudo-random, whatever) does not constitute encryption to the FCC's. This was resolved back in the early packet days and the WA4DSY 56k modems. This is true of many of the other modes/modems. And was also ruled upon by the FCC due to challenges by the anti-Pactor crowd.
