I do have some concerns that would have been addressed by Bonnie's strictures.
One, can everyone watching a waterfall display recognize a weak Federal SSB or digital signal trying to claim the frequency? Two, there are no restrictions on automatic stations. It looks to me like auto stations less than 500 Hz in width can use these frequencies also. It is unclear to me whether auto stations can meet the requirements. The classic winlink 2K scenario where a client fires up a PMBO station that inteferes with an Federal emergency conversation comes to mind as a perfect example. It would have been nice to see the ARRL address this issue directly in the regulations. The proposed rules don't address the how Federal stations will claim the frequency so that all hams know what and how to monitor when using disparate modes. If you start a pactor session, how does a Federal station break in? How does a CW qso know a Federal SSB is trying to claim the freq? You sholdn't just assume its another ham running SSB. It seems to me that it should be a requirement for amateur control operators to be able to recognize and immediately decode USB signals to insure that a SSB signal on the frequency IS NOT a Federal station before continuing. To do otherwise will ultimately result in a harmful interference or failure to relinquish claim by Federal users. Maybe not today or tommorrow but sometime in future it will happen and an emergency situation is by far the worst time to recognize that not everything was set up properly. At the same time, Federal users should know exactly what is required to claim the frequency, i.e. that a call in USB will be recognized by all hams rather than coming on frequency with a mil spec modem and making a data call. When sharing spectrum it only prudent that both sides know exactly what the "claiming" method will be so that there are no misunderstandings. Monitoring and decoding the "claiming" mode should become standard operating procedure for hams to insure it is done properly each and every time.
