ARRL “Symbol Rate” Mediation Efforts Fail

The ARRL reports it was not successful in its attempt to find common ground between proponents of Automatically Controlled Digital Stations (ACDS) on HF – primarily users of the Winlink radio e-mail protocol – and amateurs who want the frequencies available to those stations limited to prevent possible interference. The FCC is currently considering a Notice of Proposed Rule Making on the matter and the ARRL had asked for a 2-month delay in the proceeding so it could try to find consensus between the opposing viewpoints. A series of in-person meetings and teleconferences followed, but despite reaching agreement on some of the issues, neither group was willing to make a submission to the FCC based on their areas of consensus.

According to the ARRL Letter, League Washington Counsel David Siddall, K3ZJ, both groups had an “all-or-nothing approach” that precluded them from moving forward, even on areas in which they found common ground. It will now be up to the FCC to sort it all out and make a decision.
