This is pretty much my comment on RM-11305 and RM-11306. Both parties,
The ARRL and the Communications Think Tank Group are basically from
understanding, and I might be wrong, trying to change it from mode to
bandwidth so to allow new technologies on the band, or again maybe I
wrong, that was lease my understanding.
The problem I see with this is amateurs should be allowed to
experiment with new technologies regardless of how the spectrum is made
up. One of the main problems I had with experimenting hadn't been
band planning or signal size, but from amateur operators who threatened
to complain about my experimentations on the VHF/UHF bands because they
believe that it was illegal.
Back in the early to mid 90's I was very active in digital modes
including Packet, SSTV, and other digital modes, and at that time I had
began experimenting with different types of applications which were
mostly for packet radio. When I told an amateur friend that I was going
to do some experiment, an another group of amateurs "threatened" me
including complaining to the FCC to "making me have an accident".
In doing so I didn't do any experimenting. I do believe that
reinforcing the experimental parts of the VHF/UHF should be pushed and
endorsed. Even if amateurs wanted to experiment in digital modes on HF
they should be allowed as long as they don't cause malicious
interference. No changes should be made, except the attitude adjustment
of the amateur radio community towards other amateurs who wish to
experiment in new modes and applications.
