146.52 is what on the ARRL band plan back almost 40 years ?
Now lets get the repeater groups to clean up what is already being used for
repeaters move D-star to a EXPERIMENTAL band and if Echo-like is really
repeaters make they coordinate like all other repeaters ...... there wise they
go to the experminal band too ...
What's so hard about that ?

Bruce,
What 300 khz? 145.5-145.7 Mhz., per your earlier email, is 200 khz. They are
in the simplex part of the band. If you are talking about Echolink simplex
nodes or DVAR Hot Spot or DVAP simplex operation, you can make an argument that
they can live in that spectrum. However, we are talking about duplex repeater
operation here, and that must be in the repeater portion of the band, as per
the FCC, and 146.4 - 146.6 / 147.4 - 147.6 Mhz. are in the repeater portion of
the band. Those segments were misappropriated to simplex in the days when there
were more limited repeater frequencies and many FM radios (often commercial
modified) only operated from 146-148 Mhz. and 1 Mhz. split in 146-148 would
create better RX/TX isolation for repeaters.
I totally agree that coordinators need to get their act together and cleanup
paper repeaters and even make highest and best use decisions for pairs (open
and occupied is higher use than closed and quiet - and ARES/RACES teams don't
need "drill only" repeaters, they can take full use of the repeater during a
drill or real exercise and leave it open to the ham community the rest of the
time.) -- however, since they are not moving aggressively to restructure their
own plans and to clean up allocations, it is legal to put repeaters, albeit
uncoordinated, in the repeater portion of the band.
If we would become good spectrum managers, instead of emotional and
sentimental, we would redesign our band plans and start moving existing systems
around to accommodate new modes such as digital voice (at the same time we
should narrow band FM and require CTCSS or similar frequency sharing
technologies) . It has been been done before when several states went from 30
khz. spacing to 20 khz. spacing.
Again, what is the LOGIC of using limited repeater spectrum for simplex, when
there is, as you say mostly unused, simplex spectrum that could be used by
simplex operators.

WHY DO WE NEED MORE REPEATERS ?
You have 300 khz waiting for D-Star and echo-link and not one station there ....
IF there is repeater pairs not being used or just used on paper go use them ...
Here in Tampa I'll bet 90% of the repeaters have less that 10 users a week.
D-Star is 1/10 of the 2 meter users now why not go on 300 UNUSED KHZ .... ?

What logic says that when you have limited spectrum for repeaters that you are
allocating some to simplex, when there is spectrum where repeaters are not
allowed and is being under used?

NO the problem is we don't need More repeater pairs and we don't need
D-Star/echo- link on the 146.400 -146.600 or 147.400 - 147.600 pair already
used by analog stations.
