      The ARRL has now opened a page to document digital modes as required
      in the U.S. by the FCC.

      http://www.arrl.org/FandES/field/regulations/techchar/

      MT63 documentation should be complete this week, with Q15X25 to
      follow. Here is the press release:


      -----------------------

      League documents digital modes (Aug 6, 2003) -- With a new Web page
      on digital mode specifications, ARRL hopes to make answering the
      question "Is that mode legal?" a lot easier. Until 1995, the only
      permissible digital modes under Part 97 rules were RTTY and modes
      that used ASCII codes. On November 1 of that year, the FCC--acting on
      an ARRL petition--agreed to allow the use of any digital mode,
      providing its technical characteristics were "publicly documented"--
      §97.309(a)(4)--and the HF digital mode explosion began in earnest. To
      make finding technical specifications for existing and emerging
      digital modes more convenient, ARRL now provides technical
      documentation for many modes now in use on its "§97.309(a)(4)
      Technical Descriptions" page. "We needed a better place to find
      whether a technique has been published," said ARRL Technical
      Relations Manager Paul Rinaldo, W4RI, in explaining the move to make
      the information more readily available. "A place on the Web seemed to
      be the best way of letting the amateur community know that a
      technique is published as well as providing an accurate technical
      description of what it is." The documentation is adequate to
      recognize the technique or protocol when observed on the air, to
      determine the call signs of stations in communication and to read the
      content of their transmissions. The page currently contains technical
      descriptions of CLOVER, CLOVER-2000, G-TOR, PACTOR, PACTOR-II and
      PSK31. Volunteers are developing documentation for MT63, PACTOR-III,
      MFSK-16 and Q15X25 for later addition. The ARRL invites help from
      designers, manufacturers, users and user groups to fill in the gaps
      for additional modes. Send information or inquiries to ARRL Technical
      Relations Manager Paul Rinaldo, W4RI.
