D-STAR is FM isn't it. So "FM digital" simply means d-star.
No, it's GMSK.
Start speaking in the much more detailed emission types, that the FCC
uses, and all of this "confusion" about marketing jargon goes away...
"8K0F1D" gets the point across better, when planning spectrum utilization.
(If you're trying to COPY the signal, that's a completely different
specification than how much spectrum it requires and where it belongs in
a bandplan... although there are still issues like not putting
square-wave modulation types up against analog... Nextel vs. Public
Safety, anyone?)
Our local frequency coordinators are VERY clear, and use the emission
mask/type designators on our local bandplans. One can pull up the PDF's
and see exactly where 8K0F1D belongs in our spectrum here locally.
And, for all the frequency coordination group "bashing" that goes on,
most coordinators welcome input and volunteers to do the real, and
sometimes difficult work, of coming up with reasonable plans. Treading
the minefield of how to properly de-coordinate paper repeaters when past
GENERATIONS of coordinators didn't put the rules into the local by-laws,
means YEARS of changes, votes, and cooperation between spectrum users.
Unless someone has shown up at every meeting for years, volunteered for
the job, and done it... their opinions can be heard, but hold far less
weight than those actively working on the problems, in my not-so-humble
opinion.
With some (retards) being willing to file lawsuits at the drop of a hat,
and putting your PERSONAL assets at risk when you're volunteering in
leadership organizations these days, (thus the expense of carrying your
own umbrella liability policy besides the group having such, and they'd
BETTER have it... lawsuits and lawyers are expensive), and the
possibility always there of a major disruption to your life by a
(dumb-ass's) lawsuit... finding qualified people who'll work the HARD
and/or controversial issues is a difficult sell, at best.
There's also virtually zero guidance from any national organization
(Thanks for nothing ARRL -- ever think about updating your bandplans and
backing the recommendations with reasonable arguments that would help
sway the mess of different bandplans at VHF and above back to a national
STANDARD?!).
Only the brightest and most stubborn need apply. And there's plenty of
stubborn folks out there who refuse to help, too... and make all SORTS
of excuses about it.
In other words, anyone can be a "whiner in their recliner" or they can
get involved. This stuff doesn't work on, or fix, itself. Generally
coordination body complaints can be filed directly in File 13 unless
you're willing to help out. My opinion, anyway...
