Ooops. One typo, one clarification. [FH:] As of the end of the Thursday night meeting, I favor: . Drop the 300 baud limit, . Adopt 500 Hz for digital as the max bandwidth outside of the ACDS band, . Adopt 2.4 KHz within the ACDS band, . Limit ACDS stations to the ACDS band, . Require Listen Before Transmit, . Retain the Rolf, AB1PH, rule: By its language in the Rolph Order, RM-11699[1], the FCC concluded that Rolph provided no demonstration that either existing Amateur Radio or available dedicated public safety communications channels were incapable of dealing with emergency communications requirements. But then the Commission stated that "amateur stations must be capable of understanding the communications of other amateur stations." Rolph Order at para. 6. It concluded that "allow[ing] encryption to obscure the meaning of messages transmitted during emergency services operations and related training exercise would not improve or enhance the operation of amateur service station or otherwise be in the public interest."
