I just sent this off with my response.
So I'm going to still going to use Olivia MFSK until I get a letter directly from Mr. Riley Hollingsworth telling me I can't use it and why. 73 Ron KA2HZO WA5ZNU Thursday, January 06, 2005 Zulu Olivia HF MFSK Mode with Walsh FEC There is a new digital mode based on MFSK with FEC using Walsh functions, and a selectable bandwidth from 125Hz to 2KHZ. There is a mailing list, digitalradio with Yahoo Groups, for discussing it, but you need a password to read the archives. Tbe designer of the mode, Pawel Jalocha SP9VRC, has published a specification, and so US hams are now in compliance with FCC order DA 95-2106, which the ARRL says reads: "This Order amends Section 97.309(a) of the Commission's Rules...to clarify that amateur stations may use any digital code that has its technical characteristics publicly documented. This action was initiated by a letter from the American Radio Relay League, Inc. (ARRL)." Updates: See performance figures for the various configurations done by Mark N5RFX. See N1US's Olivia MFSK HowTo for Windows users. For Linux, the curses-based interface is available by contacting SP9VRC by email. Hopefully, GPL source will be available soon. - posted by Leigh @ 01:23 z ----- Original Message ----- From: Leigh L Klotz, Jr. To: digitalradio@yahoogroups.com Sent: Saturday, February 05, 2005 8:53 PM Subject: Re: [digitalradio] Olivia Ron, I have done what I can to publicise this page...do a search on 'olivia hf' and see. I provided a sound sample (generated, not off the air) to Steve Ford in response to his request. I really really wish Pawel would release the source code on his web site. The restrictions are holding back integration into existing programs, and are contributing to this FCC concern, in my opinion. 73, WA5ZNU Leigh.
