I'm in the "don't think it really matters in this day and age" group. I mean, upping the bandwidth limit may encourage more use of the spectrum since even most SCADA protocols operate at 9600 bps these days as a bare minimum.

I agree with no proprietary stuff, but think the artificial limits on symbol rate are ridiculous.

Here is another article about it from last week.

And on the other side, some amateurs were specifically asking for encryption:

It's very archaic; they probably date back to the early days when 1200 baud was as fast as you could go (and by the Rules, that's only available on 10 meters and up). Now we have modes that aren't ham related, but go a lot faster, like PACTOR IV, and many others. It's high time we were allowed to use them, as long as encryption isn't involved, of course

I would hope that ham radio is used for emergency/coordination only, once the emergency victims are in a secure location then use a secure medium for HIPPA compliance? I'm not sure what others feel about sending HIPPA protected data through amateur radio?

I do not want to see encryption on ham radio purely to prevent business use and hobbyist freedom from patent/copyright infringement (which is once again related to business). Baud rate should not, however, be limited by an artificial number, as long as it fits within the channel without leakage. What bothers me is that a lot of high bit rate codecs that could fit within the channels are proprietary (remember back in modem days over plain old telephone service, 56Kbps possible over unshielded wire? Those were all proprietary and no one have been able to legally encode/decode these signals other than with the proprietary chips or software - the Linux crowd was the most hurt from this).

HIPAA does not require secure/encrypted radio communications for emergencies. Ambulances can talk with the hospital on clear channels.
Amateur radio operators don't need to send personal identifying information over the radio.

Just another fallacy to stroke a minority of amateur radio operators egos. There is no reason that amateur radio needs to be encrypted, with the exception of the rules specific to controlling amateur satellites.

There are a number of "open" digital data modes that can be used on VHF/UHF. I don't have experience with amateur HF data, so no comments on that.

And I agree, the baud rate limit puts unnecessary restrictions on what is supposed to be a hobby service.

The issue, as I see it, is occupied bandwidth and compatibility with other modes. An Olivia 16-1000 transmission takes up a heck of a lot more bandwidth than CW or even PSK31. I don't know how many times I've been in the middle of a RTTY contact only to get clobbered by an unattended automatic Pactor or Winmor signal. Several years ago, there was a proposal to allow different bandwidths in different parts of the band, but the proposal met with much resistance, probably because of the way it was worded.

As for Pactor 4, the proprietary nature of that mode would seem to exclude it from amateur radio. And, then there's the cost. Approximately $1500 for a proprietary, single-source modem? I don't think so.

The way these modes are used is a valid concern, too. I always thought that amateur radio was a communications medium for radio hobbyists and was specifically not a replacement for other radio services. In my opinion, if the captain of an ocean-going vessel wants to exchange email with folks on the Internet, a satellite-based service would be more appropriate than amateur radio.
